It seems that the renderman surface shader is not sent to the engine. the displacement shader yes but not the surface one.
Let's put a cube in the scene.
Add a renderman surface shader like bluemarble.
Add a renderman displacement shader like dented.
render with the bundled aqsis
Result: one purely white cube.
If I lower Ka in the surface shader, k3d renders a gray cube WITH the displacement shader.
I'm on Vi$ta32. I have no errors in the log window.
Can you help me. Thanks in advance.
