Hi everybody, thought I'd throw up a simple file to demo the problem,
In the context of rendering a flip sim mesh in mantra, with the env geometry as both holdout 'forced matte' and 'forced phantom' to have it still show up in reflections and refractions,
I have a situation where by adding the object as forced phantom, it cancels out force matte.
But as a work-around - it seems if I duplicate that same env geometry, by copy&pasting the sop, and setting that new sop to be the phantom and not the original, mantra renders as expected.
Go figure...
Cheers,
Matt
