I have a .dds texture which has R, G, B, and Alpha channels. The Alpha channel stores the transparency info. I have this file open in Photoshop.
I want to convert this to a .png file.
What's the best way to go about doing this?
Doubleclick on background layer to make it floating. Load the alpha channel as a selection (select menu or from channels palette). Invert selection hit delete.
If your image was premultiplied by color then defringe or remove black white matte but if it was not you dont need to do thism
