Hi there,

I'm new to this forum and could need some help with Renderman Shaders.

I have a Problem with compiling .sl files.

In a tutorial I wrote a very simple shader, but when I try to compile with shader.exe I get this message:

ERROR: Cannot find preprocessor for shader file "basic.sl"

What is the prepocessor?
Is there maybe some environment variable set wrong?

I'm using RMan Studio 1.0.1

Thanks a lot in advance
Markus

Sounds like you haven't set the RMANTREE environment variable. Set that and you should be able to compile the shader.
