Render Mask - Refraction

[wolfgang_himmelfarb]

So I am aware that render mask doesn't work through materials with refraction which is not ideal because architecture typically involves glass. I am wondering if we are stuck with this technical limitation or whether it can be solved? If the latter, I'd be happy to add it to the requests portal.

I don't know if this is helpful for you. Enabling this option will allow the mask to penetrate the glass

I have that set for both reflection and refraction. If you've ever done animation and need to render out just a single object the "render mask mode" is very useful but it doesn't work for object behind refractive objects like glass.

Sorry there's another one - there is also an issue with objects that have opacity maps or really any opacity value showing up in the render mast without it being specified as object, active selection, object id, etc.

I was just looking to see if anyone had mentioned this bug. Thanks for posting about it, I am running into this issue now and wish my materials did not have opacity maps. Unfortunately, because they do, I cannot render out clean render masks. I assume this is not the intended behavior, and I hope it can be fixed, too.

I believe Max doesn't have either issue - when I used it last, for an animated shot I had zero issues. I remember thinking how amazing and useful it was however since moving to Cinema I don't even think to use it bc it's basically broken - you can't have objects behind refraction or opacity in your scene(!?!).

tbh, it makes paying $80per month kinda hurt if you don't use Max.

wolfgang_himmelfarb Maybe this will work for you too.

I found that if I switch the texture sampling in the bitmap shader to "None" instead of the default "MIP", I am able to get a clean render mask. Hopefully this helps.
