Problem with After Effects Masks and DXV rendering

Hello all,

I'm having some trouble to prepare my material for resolume. In adobe After effects I have two different layers and both have differents masks. If I render out the video in something different than DXV I have the expected output (As seen in picture MasksOk.png). But when I render the animation in DXV I have problems with the transparency of the masks, as you can see some of the content from the layer that is beneath it (As seen in picture masksNotOk.png).

Im rendering the animation with DXV 3, normal quality, no alpha, 32 bits. Has someone experienced something similar?

Any help is appreciated.

Looks like you're rendering with a straight alpha channel from AE, and telling Resolume to interpret it as premultiplied.

Either switch the alpha channel to straight in Resolume, or render premult out of AE.

One of my favorite topics! Here is thread that might help you understand how alpha mattes work.
