when i press the render button, and i got a warning signal.

S01001 {WARNING} Cannot load shader “first”. (System Error: No such file or directory)

why? :cry:

Well obvious prman can't find the shader. So you could check if you do have a shader called first in your houdini scene and if so, you could check the rib file to see if it references the right path. You can create a rib by using a RIB archive rendernode iirc.

Here is a link for all the renderman error messages

Hope this helps

Have you set the shader path for the renderman rop?

Thank you, guys~
