Can I clarify, that when I use a ColorOp of BLENDTEXTUREALPHA, that this affects only the RGB values of the output color, and that if I use SELECTARG1 as the AlphaOp and TEXTURE as the AlphaArg1 this should still output the final alpha value as the same as the texture pixel? Also, when it says it uses the alpha value from the texture to do the blend, does it really mean the texture, or does it mean the result of the alpha operation from that stage? So, is the final RGBA pixel value the RGB from the Color stages and the A value from the alpha stages? Thanks [Edited by - Raeldor on November 26, 2005 1:37:09 AM]

No, (maybe I'm not right,if so please correct me :) ). As far as I know, the TEXTURE alphaarg is the alpha value of the texture pixel(texel). If you want the resulting value from the stages(color or alpha) you should use CURRENT.
