ShaderFx in Max

stav2se

Hi guys,
As I am quite new with 3D modelling I would like some guidance if possible.
I am currently creating a generic race track and I am stuck when trying to apply multiple maps and uvs on the outside terrain of the track. When I change the UV index number in shaderfx to match the unwrap modifier UV channel the whole area I have applied this texture goes crazy and looks broken. 
I would really appreciate if anyone has any ideas. Thanks a lot in advance

It's been a while, but the UV index in Shader FX might be zero-based, while 3ds Max is one-based.

It's a bit erratic in maya and I wouldn't be surprised if its the same in max. 

Eric is thinking along the right lines although it may be the other way around.

Hi guys, thank you so much for coming back to me. @Eric Chadwick does that mean that I have to modify the actual shader? or is there another way around it?

Eric Chadwick

I don't think you have to change the shader. Just use UV channel 1 in the modifier if the shader is using 0, or 2 if 1. It's that simple.

Thank you so much Eric, I cant believe it was that simple . Really appreciate your help
