    Alpha Channel in AE renders Wrong




      I am importing a 3D Render from Lightwave with a Premultiplied Alpha in AE as a Targe Sequence.

      If I compare the render when I comp it on top a AE Solid with the Output of Fusion for example I get a very different/wrong comp if there a transparent/Motionblurred parts in the 3D Render.


      Here is a Comparison with a render of 8 Cubes and comped in Fusion and AE (once interpreted as Straight and once as Premultiplied) over White, Black and a Color.

      Here is the 3D Render and the Alpha Channel:


      As you can see the rendering of Fusion is What I would call Right. What is AE doing and why?

      How can I get the same output in AE?
