I have a scene with 2 layers, the rough raster layer, and the clean vector layer.
Onionskin works fine on the raster layer, but on the vector level, I get no paper thickness/opacity change. All before and after frames are full black lines.
Vector onion skin will work it I turn on transparency check, but that makes a black mess of my rough raster layer, which I also need. Is it possible to have them both with paper thickness working?
