I need to export frames with transparency. When I use Export - > OpenGL Frames and choose PNG4 I get my artwork with transparency, but the alpha is all random blocks of noise (as a programmer it looks like dirty memory) - please see attachment (it should only be red lips on transparent background)
If I choose PSD4, the same thing happens to the Alpha channel - its full of noise.
If I choose Export → Layout Image, choose PNG4 it works as expected - no problems with the transparency. But I need all the frames exported, and as far as I can tell that only exports a single image.
If I choose Export → Render Write Nodes, it exports TGA without an alpha channel, and I don’t see any way to choose a file format with alpha.
I hope there is a way to make this work, otherwise my evaluation ends here.
