Its not because of the alpha channel of course!! im not stupid, its because of the glow effects, bevel effects and everything that gives the layers effects to read them... same for shadow effect,it would simplify alot some effects, and im saying this because im working and i know what work you have to wast just to use glow effects with alpha channel.
Perhaps are you using effects that blend, mix with or use the background image beneath?
That won't work exactly the same within 3DGS as the effects won't work there. Setting a layer to 'multiply' for example, won't have the Photoshop multiply effect within 3DGS.
A small hint though; make a screenshot of your project and do all your effect testing there. Make sure none of the lower layers do any kind of multiplying or other effects using the layer beneath it (your screenshot). Then you should have no problems. Also, yes.. transparent can turn into white,
Cheers
