Jak170 Posted October 20, 2008 Share Posted October 20, 2008 I've browsed around and have heard someone doing this or that to the alpha channel to change the way a texture looks. What exactly is an alpha channel and how does it work? 0 Quote Link to comment Share on other sites More sharing options...
Scipio Posted October 20, 2008 Share Posted October 20, 2008 CMSF textures are bitmaps, or to be exact 32bit RGBA bitmaps in BMP file format. Each pixel uses 8 bit to define the red, green and blue value + 8 bit for the magic alpha channel, wish defines the level of transparency. Sounds very simple, but working with BMP-alpha channel is a nightmare. I've started a thread about it just today! 0 Quote Link to comment Share on other sites More sharing options...

Hi Scipio, over at the other thread and in response to NormalDude's raising of the point about some alpha's not working; I think some of the materials on the models themselves only use 16 or 24 bit bmp files and thus are intrinsically at the model level not able to handle the extra channel with alpha info. 0 Quote Link to comment Share on other sites More sharing options...
