Hi, I have nebulas made from particle clouds and 3D paint brushes. When I render, the image looks fine in Maya. However I want to include the alpha channel so I can composite in the background starfield. When I export the image from the render view window as an .iff file and import it into photoshop, the brush tool effects are really faint. Is there any way to fix this?I tried lowering the transparency on the tube shading and shading channels but the stars are still faint. I noticed that when I render out the stars with rgb and alpha, I'm just getting the alpha channel for the stars.
