even though the shader has set blend blend, the alpha is completely ignored.
does anyone know how to fix this ?
parsonsbear@Posted: Mon Nov 12, 2007 12:39 pm : maybe your image's alpha channel isn't correct- can you use makealpha with the shader just to check that it's possible?
TTK-Bandit@Posted: Mon Nov 12, 2007 12:50 pm : the alpha channel is correct, the image works if I use it normally, the problem only exist when I use uploadimage.

zl1corvette@Posted: Wed Dec 26, 2007 4:50 am : Try a listImages in the console and see what format the image is loaded as. If it's rgb or dxt1 I believe there needs to be an 'A' at the end of the format to indicate an alpha channel. Dxt3&5 always have the alpha channel IIRC.
