Hi Team,
I'm using a Vray MetaImageFile to drive the opacity of our material. Sometimes we don't have an opacity texture so I've set the default colour of this node to 1,1,1,1 for when the bitmap path is empty (see pic)
With CPU rendering this works okay and the default colour is respected. However, when using RTX or CUDA rendering this Image Node seems to always pass 0 to the opacity input regardless of what I set as default colour. I've added a hard coded float node that forces the opacity to 1 and this works with RTX/CUDA.
Please could you take a look at the attached hip (in the zip) and let me know if this is a bug or whether there's something I need to toggle on to get this working for RTX/CUDA.
Thanks a lot,
Chris
