Going nuts with this and searched the forum or web. Either I am not typing in the right search string or something else. How do you use a tree texture image that has a premultiplied alpha map integral to the texture image? ImageCels all do this using a pre-multiplied tif file. They do not supply a separate opacity mask. I have tried several things and nothing is working. I sure hope I do not need to create a opacity image for each of these objects. Thanks!!
