3ds Max

In Particle Materials take the empty slot and use these settings:

• Diffuse: RGB: 150, 150, 150
• Specular Level: 53
• Glossiness: 55

In Maps use these settings:

• Reflection: Reflect/Refract
• Refraction: Raytract
• Text Material Diffuse: RGB: 242, 247, 252
• Specular Levels: 95
• Glossiness: 16

Now do a test render. You can see the image is not good at all because there is an anti-aliasing problem (Fig.10).

As you look closely at the final video, you can only see the text in the reflections on the bars; you can't see it directly. Right-click on the text, then go to Object Properties and uncheck Visible to the Camera. After doing this you will only see the text in the reflections (Fig.11).

Here's a quick test result (Fig.12).

To get a good result in the final render we should tweak some settings. I'm using Scanline Renderer for this effect. Go to the Renderer tab, and in the Antialiasing section set Filter to Mitchell-Netravali, and Blur to 1.0. In the Global Super Sampling section, tick Enable Global Supersampler, select Hammersley and set Quality to 1.0 (Fig.13).

Render the scene and here's the final result (Video.01).

That's it - I hope it's been informative.

Cool looking tutorial but it seems like you left out a few things. Initially the objects that were instanced are all bunched up in the center of the screen and only by moving the slider a few frame will the objects be what your first frame looked like. Also the fact that you failed to show how you played with the curve editor to slow down the movement of the objects and/or camera, or if you even did that in Max. This tutorial is good but could have been better with more information.

I am using 3ds Max 9 sp-2 and i used the settings for particle view. But the result of it is different from the picture. Any changes?
