[C4D] General Discussion / about alpha masks for compositing
« on: 2017-03-27, 12:56:57 »
Hi everyone,
first of all I'd like to say that I love Corona and thanks to it I've totally let AR down in C4D (until then I didn't really try another render engine).
It's just madness with new Ryzen 1800X+ GTX1070 config !
That said, I'm facing a problem : I can't get an alpha mask on specific item whatever the tag I assign or not to it.
I always get a mask on all the items of my scene (wich is quite a problem with full frame L-shape background > the mask is fully white).
I assume that I'm probably missing something.
Please see the attached picture.
Could you please give a link that explain how it works or tell me here where is the trick?
Thank you so much in advance.
