Hey Mike
Maybe you could try to explicitly set the image type (texture/imageFile) to
image file?
pm.setAttr(ibl+'.type', 1) # to use an image file
pm.setAttr(ibl+'.type', 0) # to use a texture
Maybe you could try and set it to use a texture for now and see if that works.
If that actually works, you could point it to a texture file node and load an
image file from there?
Not the most elegant solution, but I believe that'll work.
Let me know if any of it helps :)
Best Regards,
Patrick
