If I use an op reference in a texture field of a mantra surface shader, such as:
opobj/geo1/cop2net1/texture
it will render correctly within Houdini using the render view, but show up as pink (missing) when rendered using hbatch. Hbatch has no complaints about not finding it (as when the path is incorrect).
This smells like a bug. This worked fine in H8, so I'm suspecting it's broken in H10. I'm using H 10.0.295 on Windows XP.
Any ideas?
