I assume you know what is UVW modifier. Some folks may ask how to apply to different polys. It can be done by several simple steps.

Convert object to editable poly first. Go to poly level. Choose the polys that you want to apply. After that, choose UVW Map from the modifier list. If you need to apply to other polys with unique UVW Map modifier, apply Poly Select modifier to the object. Go to the Poly Select modifier. Then, highlight the polys that you want to apply. Apply UVW Map modifier. Repeat the above steps if you need.

What's Ambient Occlusion?

Ambient Occlusion is an important element of CG as it can noticably raise reality of pieces. It is used for soften the shadows that fall on corners of objects.

How to create Ambient Occlusion?

Create a mental ray material. Put Ambient/Reflective Occlusion into the surface slot. Then, edit the parameters of AO. Adjust the number of samples. The higher the value, the better the quality. It's important for you to adjust the max distance. It determines how deep will the AO pass be rendered. Put a suitable value into it. The material is done. Open the Render Setup window. Enable Material Override which is below the Processing tab. Drag the mental ray material into the Material Override slot. Choose Instance. Make sure that you have turned off GI, FG and exposure before rendering the pass. Click Render.

After the AO pass is rendered, you need to composite the pass with the original render manually. This can be done with Photoshop. Add two layers and put the AO pass onto the top layer. Adjust the opacity of the AO pass. If the opacity is too high or too low, opposite effect will be resulted.

10-minute email is not newly invented actually, it's worth introducing though. At first, what is 10-minute email? The meaning is more or less the same as its name - the email accounts that are only valid within 10 minutes. It is easy to register and convenient to use. With one unbelievably simple step, clicking the register link, your account is then created. You do not need to input your personal data. The email address will be given randomly.

The vast majority of people use it for registering accounts online. They are not tend to receive newsletters from the websites that you registered as members. 10-minute e-mail account suits their need. You can register accounts with the temporary e-mail accounts. Then you will be no longer troubled by the newsletters.

After creating a ragdoll, the Simulation Geometry of the legs, arms are set as Bounding Box by default. You cannot perform realistic simulations with legs and arms set as Bounding Box. In order to optimize simulations, you may change the Simulation Geometry from Bounding Box to Mesh Convex Hull.

Why do I need to change the Simulation Geometry into Mesh Convex Hull?

When you perform a ragdoll simulation with Bounding Box, the legs and arms of the ragdoll will bounce weirdly after they fell of ground. This can be solved by using Mesh Convex Hull instead of Bounding Box.

As I think it is a precious exprience, it's worth to share it, although this is a CG blog. Anyway, there are several knacks to boost your traffic.

-Adding your blog to search index
It's really simple. You may add your blog to the search index of Google. Frankly, the main source of my traffic is also coming from Google. To submit your blog to Google, you may click the hyperlink About Google at the bottom part of the Google page. Then you will see a link called Submit your content to Google. After that, you may follow the instruction to submit your blog.

-Submitting the feed of your blog
You can easily create your own feed with FeedBurner or other software and submit them to RSS feeds collecting websites.

-Be active on forums
Being active in forums is important in boosting traffic. It does help increasing the number of vistors noticebly. You add the link of your blog in the signature. When people read your threads, they will click your link curiously. It really boosts your traffic but most of the visitors might leave immediately because they are not patient to read your content. You may make a big flash banner so as to seek their attention (include brief description about your blog). Then, they might intend to read your content.

These are my tips. They helps a lot. Hope you would like them.

This is my first attempt of creating better-quality animation. Any comments are appreciated.

This is done for fun.

This is done for fun. You may download it if you like it.

After the post of AREA, I want to provide more information about useful resources especailly for CG artists. You can't live without this website - The-Blueprints.com. It is a extremely useful website. It collects abundant blueprints for CG artists. It is almost impossible for you to model a complicated object without the help of blueprints. However, most of them are mechanical blueprints and some of their resolutions are very low. It can't be used in modeling. Anyway, you may try your best to find out what you want. The-Blueprints.com


AREA a part of autodesk official website. The users interchange their knowledge and opinions on the site. The site has abundant resources such as tutorials and textures library. You can find the things you want their. What's more, you may obtain help and support by posting your questions on the forum.

If you are looking for some CG works to inspire your next project, you may check the CG works out in the Image Gallery. It has wide variety of works such as architecture or even Sci-fi works. Just check it out! http://area.autodesk.com/

Army Men: Toys in Space an amusing and exciting game, it is shown in 2D way though. The game is quite unique because I have never played any video games which is about war between plastic soldiers.

This game has serval pros:

-No hardware requirement
The only requirement of this game is a computer! No special powerful hardware is needed. (because it is an old game :) )

-Experience breathtaking wars
Grenades and rifles makes wars become breathtaking.

-Highly customizable
The game is crammed with different kinds of soidiers such as grenadier and firethrower. You may also form the squads you like.

For further information, you may go to download.com (download link).

I guess you know what is Google Earth. The new features enables users to travel around the world more in a more enjoyable way.

There a few new features in Google Earth 4.3:

-Photo-realistic Buildings
Many famous buildings and landmarks are shown in a 3D way. They are created with a software called SketchUp. This feature enables you to view buildings more clearly.

-Light and Shadow
With this feature, you can view stunning sunrise and sunset anywhere you like. The shadow cast by mountains enhances the reality.

-Street View
You can view the streets in a 360 way. It's interesting to experience.

This is my latest work. Any comments are much appreciated! :)


ObjectDock is designed by a company called Stardock. It's a highly customizable bar that enable users to put the shortcuts they like into the dock. This helps cleaning up your desktop efficiently. The dock can be well-organised also. You may add seperators at the positions you want. There are some built-in shortcuts such as web search and weather forecast. I experienced the clean and I get only three shortcuts on the desktop! This is the download link (download.com).

This is the interface of ObjectDock. You may change the theme you like.

This is my first attempt of creating video tutorial. Apologize for any shortcomings.

Madagascar 2 is scheduled to be released on November 7, 2008. I had seen the first episode and it's really great. The ending is interesting. That's my favourite part. It's one of my favourite DreamWorks animation. Give it a big hand. :) Looking forward to seeing the second episode. Here is the trailer. Enjoy!

This is the animation I've done recently. It's just for fun. Enjoy!

This is the latest coca cola advertisment. It integrated with CG. I think the best part is the "bird nest" built. Enjoy!

In this tutorial, I would like to talk about how to create a realistic table cloth by using cloth modifier. Cloth modifier is really useful while simulating the motion of cloth. We will make use of cloth modifier to create a table cloth.
Download the PDF version: table_cloth.zip
1. Create a plane, a chamfer box and four boxs as the legs of the table. The plane is the table cloth.
2. Apply Cloth modifier to the plane.

3. Click on Object Properties. Click Add Object in the Object Properties window. Then, choose "ChamferBox01" and click OK.

4. Choose "ChamferBox01" in Object Properties window and choose Collision Object. This set the ChamferBox01 be the collision object (that mean where the table cloth will be held).
5. Choose "Plane01" and choose Cloth to set the plane be a cloth.
6. Set the amount of Self Collision as 1.
7. Click Simulate Local. Then, the simulation will be started.
Note: if the simulation is not proceeded normally, you may delete the Cloth modifier of both plane and chamfer box and thicken the chamfer box.
8. After you think the shape of the table cloth is acceptable, you may click Simulate Local once again in order to stop the simulation.
9. Apply Shell and TurboSmooth modifier to the plane to make it looks more smooth and realistic.
I apologize for any shortcomings and mistakes.

AfterBurn is the certificated animation plug-in of 3ds max. Many top-rated games and films use it to produce CG effects. It allows users to create ultrarealistic clouds, dust, explosions, liquid metals, water. For more details, you may visit the official website of AfterBurn.
Dreamscape is also one of the certificated plug-ins of 3ds max. It is used for creating and rendering realistic natural environment. It allows users to create sea, terrain, clouds etc. Many of films use it to create CG effects also such as The Day After Tomorrow, Spider-Man 2.
For more detail, you may visit the official website of Dreamscape and Afterburn.

Nowadays, very few people using PrintScreen function that built-in in Windows to write tutorials. Because it is so terrible that you need to copy and paste frequently and manually. It is a waste of time. This time, I would introduce other tools that are useful for writing tutorials.
If you prefer video tutorials, you may try CamStudio. CamStudio is use for capturing motion on screen. You may adjust the quality as you like. It provides some useful functions such as highlighting cursor. Many video tutorials are made by CamStudio so I think it is worth trying.
If you prefer capturing static images on screen, you may try ScreenshotCaptor. It provides image edting functions. After captuing images, it will appear a window for you to edit the image. It is great for writing tutorials because it provides the functions of creating arrows, texts and brackets in an easy way. It also can create blur effects. There are some shortcuts for you to capture the screen. The shortcut of caturing the selected region is Shift+PrintScreen and the shortcut of capturing the active window is Alt+PrintScreen.

I'm working on apache at the moment. I am still modeling it. This is the latest progress. If you want to see the whole procedures, you may go to this website. click on the link

I will talk about how to model a LCD monitor by 3ds max in this tutorial.
Download the PDF version here: LCD_monitor.zip

1. Create a plane with length and width set to 500 in front viewport. Apply the reference image to the plane. Click F4 after applying. Remember to enable viewing the texture in viewport by clicking the button Show Map in Viewport.

2. Create a box with height set to 14. The box should be covering the area of the monitor. After that, right-click on the box and choose Properties. Tick the box see-through in order to see the blueprint clearly.

3. Inset the selected poly shown in the image a bit.

4. After that, extrude the poly inwards.

5. Select the corners edges by selecting one of them and click Ring. Then, click Chamfer and chamfer the selected edges a bit.

6. Create a line as the image shown. Then, switch to segment mode. Choose the segment and click mirror. Remember to enable Copy before mirror the segment.

7. Click Extrude. Set the extrude amount as 4.

8. Apply a Edit Poly modifier. Then, Choose edge mode and click chamfer, chamfer all the edges except the middle two.

9. Rotate the base along X axis a bit.

10. Create a line like this. Maybe a little bit thicker.

11. Apply Extrude modifier to the spline.

12. Apply Edit Poly modifier to the extruded spline. Move the edge that pointed by the red arrow a bit backwards. Then, chamfer edge that pointed by the second arrow (in the perspective viewport.

13. Chamfer all the edges except the four that have been chamfered in the previous step.

14. Apply Symmetry modifier to the extruded spline. Tick the checkbox Flip.

15. Click on the Symmetry modifier and move the mirror to the position shown in the image.

What Lens Effects Glow does?

Lens effects glow is commonly used in interior scenes. It makes the scenes look brighter and give warm feel.

How can I get it done?

To create Lens Effects Glow, you must have a camera in the scene. Click "Rendering> Video Post...". After that, click Add Scene Event. Choose the camera that you want to have Lens Effects Glow. If you are only rendering a static image, you may set the VP Start and End Time to 0. Then, click Add Image Filter Event. Choose Lens Effects Glow. Set the VP Start and End Time to 0 also. Then, click Setup. After that, choose Whole if you want the whole scene has the effect. Then, click VP Queue and Preview. This enable you to preview the effect and make adjustment. You may adjust the size and the intensity in the Preference tag. After finishing all adjustment, you may click OK and click Execute Sequence.

This time, I would talk about how to get a better result while using Mental Ray. In the tag Renderer, there are many options that we should pay attention while doing rendering. Sometimes, you will get a bad result. This might be due to the low samples per pixel. The larger the amount, the better the result. It is set as 1/4 and 4 for minimum and maximum in default respectively. Generally, I will set them as 4 and 16 for minimum and maximum respectively. This is enough for rendering a good quality image.
Then, I would like to talk about the filter. There are 5 types of filter. They are Box, Gauss, Triangle, Mitchell and Lanczos. It is set Box in default. Each of them has different calculating method. Box gives the worst quality while Lanczos gives the best quality. Generally, rendering with Mitchell can get great results already.

As said in the title, this book talks about how to render with mental ray in 3ds max. It brings you into mental ray. The author helps you to learn mental ray inside and out. It start by explaining the essential concepts. It helps beginners to build a firm foundation. This book explained mental ray detailedly-from lighting to shaders. It shows you the procedures. Rendering with Mental Ray & 3ds Max will help you cope with the difficulties on mental ray.

Vue 6 Xstream is used for creating natural environment. It is easy to learn and use. For me, I have just spent one day and I can create a simple but great scene. As said in the title, Vue 6 Xstream is used for creating and integrating. It can export as various format such as .3ds, .obj etc. It is highly compatible. It can import various formats. There is a free PLE version. For more detail information, you may go to this website.

While creating a large-scale scene, you will use a lot of materials. The slots might not be enough. You can solve this problem by deleting materials in the editor. First, choose the materials that you want to delete in the editor. Then, click the cross that just under the sample windows. After that, there would be a dialog appear. Choose "affect only mtl/map in the editor slot". You can edit the materials again by using the dropper. After clicking the dropper, click on the object that you want to edit. Then its material would be shown in the slot.

Really cool! Very realistic simulation.

While modeling with blueprints, many people will apply a translucent material to the object. But it is a bit trouble if you need to apply the material to the object every time. There is another better method. Right click the object and click Properties. Then, tick the box "See Through". This enables you to see through the object so that you can see the blueprint.

Sometimes, you may suffer from lagging when 3ds max is handling huge amount of polys. In order to solve the problem, you may right click on the object and click Properties. Then, tick the box "display as box". You will see the object change to a bounding box. This can increase the efficiency of 3ds max. But the best way is using polys efficiently.


I know the rendering is a mess in this rendering. I have spent a month on this project, since I am lazy.


I have spent 3 weeks on this project. Used Daylight ( IES Sun and Sky) as the light source. The background is a photo.

USB Flash Drive

This is my USB flash drive. Rendered with MR with FG and GI enabled. Used Daylight as the light source. Basically, only the USB flash drive is newly created in this project. The rest are come from one of my old project.

F-22 raptor

This is my first work done by box modeling. The real texture is not like this, of course. I want to make it looks more sci-fi so I created a shiny texture for it.

DVD player

This is done in earlier time. Just a DVD player with a DVD and a remote. Rendered with Mental Ray. Actually, I am not quite satisfied with it because it is not detail enough especially the buttons.
