sanostol Posted July 8, 2010 Share Posted July 8, 2010 I want to have do shader that adds in transparent parts, for example if many grids with this shader are on top of each other their color gets added together. right now the color is mixed, but never gets brighter than the original surface color. what I want to achive if i look through 10 grids with this shader, that has a color of {1,0,0} and a opacity of 0.2 their color is added and the color should be something like {2,0,0} Martin Quote Link to comment Share on other sites More sharing options...
stu Posted July 8, 2010 Share Posted July 8, 2010 If you don't reflect the object's opacity in it's alpha and leave the alpha at 0, the resulting combination is additive. ie. the object's transparency is something less than 1 but greater than 0, and the alpha is 0.
