Which shader for Bogie

[aksingha]

Hi,
Which shader should i use for bogies. The Bogie has some words on it and i want the words to get a bump look. I have made the normal map using nvidia filter, but don't know which shader to use.

TrainBumpSpecEnvMask.fx should work fine.

Ok, so i guess i will have to remove alpha from the texture, since the bogie don't need any specular shine.

Hi, in that case, you would need a very dark alpha, removing it would make it all white and have the opposite effect and make the parts very glossy.

However, you could also try TrainBumpSpec.fx, works great for both dull and 'greasy' metal parts in my opinion.

Michael, for the TrainBumpSpec.fx shader what types of images are you using? I'm assuming that the first is the diffuse color but I get confused about the alpha and is there a second image involved? The Art of Railworks blog says use a normal map for the second image but the Blender exporter doesn't like a second image file. Trying to make shiny wheels and failing.

You have to assign the image to a second channel of the main image. Doesn't blender allow for a separate channel?
