xtimmyx Posted September 29, 2009 Share Posted September 29, 2009 I'm trying to export some extra image planes/shader buffers for my render. But I can't seem to get them to take the alpha of my textures into account and cut it away, like it does in the composited image. (In my case there is a bunch of feathers over a bird body, but in my image planes they are rendered as solid planes with no alpha). I've tried exporting the image planes as a Vector4 supplying the alpha as the fourth channel, but that doesn't seem to make any difference. Is this at all possible? I'd like to export some occlusion and stuff without re-rendering the frame. Quote Link to comment Share on other sites More sharing options...
sam.h Posted September 30, 2009 Share Posted September 30, 2009 In your shader, multiply by the alpha before exporting. Quote Link to comment Share on other sites More sharing options...
xtimmyx Posted September 30, 2009 Author Share Posted September 30, 2009 In your shader, multiply by the alpha before exporting. That did it! I find it quite strange however, since I'm multiplying with black I thought it would just output black in that area, and not transparency.
