Thanks, that works! How would I modify that to use a texture plugged into basecolor instead of using the texture parameter on the principled shader itself? I've tried promoting the map parameter from the texture node and then adding that to the edit properties lop, but that doesn't change the texture path in the shader.

How can I use an animated texture sequence in Solaris/Karma? i.e. /path/to/mytexture.$F.exr

Neither the principled shader nor the texture node will read the texture at all with $F in the path (I've tried adding the path to the rendering parameters on the containing material library as well to see if that would work but no). The OSL texture will read the texture but the expansion of $F seems to get baked in to the shader compile as it doesn't change when the frame changes.

Ahhh good to know, thanks. On a similar note I can't seem to get Karma to output an albedo/color pass. Is there a special variable name (using the principled shader) for that or is it not supported?
