Hi guys,
First post, respect and love for Creative Cow.
Following up on this, I have the same problem and didn’t find any other source on the web.

Last version of AE, on mac. When I import a PNG or an AI with transparency and turn it into a 3D layer in AE the transparency in that layer turns to black.
Following this tread, I fiddled with RGB/CMYK, turning layers to 2D/3D, changing camera view.

I maybe missed something, but I’m still stuck and while I usually find my answers here, I had to register and show up for this one. Could anyone help further? Thank you
