If understood correctly the documentation shows no Blendmode SUBTRACT.
There’s also no way to disable RGB or ALPHA for drawingoperations? You are always forced to do everything you do to affect both RGB and ALPHA as a pair.
Sometimes it makes sense to differentiate between the two. For example now we’re trying to acomplish shadows (you can do that in many ways of course but they way we have implemented it needs to be able to affect only alpha. Is there a chance for these two add-ons?
with monkey and 2d thank of any graphics (images) as having an added color and alpha.
so (lets say) a white star, can be draw in any color and any alpha. So if you want four stars, one red, one blue, one green and one white.
You just need to have one white star and draw it using different color commands
