TextureTransfer doesn't transfer alpha channel

Hello,

I am running into an issue where the textureTransfer bake doesn't preserve the alpha of the texture.  I am fairly certain this used to work.  Is that a bug, does the new baker not support alpha transfer, or am I just overlooking something somewhere?  I was running throught the SAT, but it also just results in a white alpha channel when baking manually in designer.

Thanks,

Chris
