EdgeUp 1.1- FREE plugin for 3D Studio MAX -
The EdgeUp plugin is a FREE filter plugin for 3D Studio MAX R2.0. Render your animation against a black background (RGB 0,0,0). This filter will reverse the blend process towards the background made by MAX on the edges of objects and on transparent materials. If you use the alpha compositor in the video post or composite in another 3D package or video editing system. It will use the alpha channel to blend the edges correctly against the current background.
NOTE! The RGB values in the image can look really strange, especially if you have highly transparent objects. This will look OK when you have made the composite.
