Hi,
Any idea why an avi file set as environment map in max (screen) will not render animated? It always renders frame 1 in the background. I even can't get it to animate in the viewport background (I ticked 'animated background' in the viewport background properties).
Also, if you have an object on top of a matte plane, how can you render the shadows, caustics and GI shadows with correct alpha channel so that it can be composited over the background later? When I tick the affect alpha option in the matte properties, it only takes into account the raytraced shadows and part of the shadow pixels contain the background image. So if you for example choose another background in the video editor you will still see the old background partially in the shadows.
Or is the only way to do this to render every single element seperately (so no alpha channel on the shadow) and then blend them together with the correct blending modes?
