I'm having problems using video rotoscoped with the PAR (thanks Greg, is working wonderful) as a decal. I wish to use all the frame as opaque using an all white alpha channel, but I have no success with this. The Material Editor does not recognize an all white alpha channel. I tried this as a check: 1.- I rendered an object that does not fill the viewport with alpha on and alpha split set to no. I can view in the material editor the alpha channel. 2.- I scaled the same object to fill all the viewport, rendered again, and now the material editor says the image does not have alpha channel, but the file sizes and Photoshop confirmed that the extra channel is present. 3.- As a test, with Photoshop I blackened a single pixel in the alpha channel of test 2, and now the Material Editor shows it and admits its existence. Any help is very appreciated, Vanny
