TrailRenderer colors in code

Unity Engine
1

Sorry for all the questions, but I’m stumped on this one. The TrailRenderer component has an array of colors that you can customize in the Unity GUI. I would like to customize them in script, but I can’t figure out how to do it (as the colors array is apparently not a modifiable field of the class??). For now, I’m only worried about alpha, though having access to the other properties would be nice. I tried to alter the alpha through the material, but when I try to set the material color, I get an error which essentially tells me that the shader doesn’t have a “_Color” property. I tried the other common properties (SpecColor, EmissiveColor, etc.) but didn’t find anything. I’m using the provided “Particles/Additive” shader.

Any thoughts on how to access the colors array?
Alternatively: Any way to view the properties of the shader? (I don’t know where to find the shader code source)

Thanks as always! I really appreciate it!

Try making another material in the color that you need to change to and then material.Lerp to it.

You can download the built in shaders here:

I think you can’t access the trail renderer’s colors through code. You can however roll your own (I did right here: http://forum.unity3d.com/viewtopic.php?t=5246)
