I have a shader works with maya but not houdini, it seems the uv coordinate problem.

I can see the uv from the file sop, and I can see the uv is correct from the uv viewport, but when I render, the uv coordinate works bad. It seems that the UV didn't pass to the shader.

here is my file.

maybe add and attribute SOP and in the renderman tab map uv to st

I had tried that, used attribute sop to map uv->st, but still not work… I need help….
