I have a scenario,which involves smoke and fire.
I code them respectively with shaders and points.
Smoke use alpha blending and fire use additive blending.
So alpha blending equation is
SRC*alphaFactor + DST*(1-alphaFactor)
additive blending is
It may happens to one pixel that needs to render both of them.
in this case , are they shares the same input frag color or one of them s out frag color is the other ones input frag color?
I don’t know if there’s any problem with that but the thing is that the fire is too bright.It covers the smoke instead of blocked by the smoke in front of it.
