**mixing holdout with transparent in an eevee shader nodes behaves unexpected.**
holdout and transparent in a mix node.
- it looks like the transparent bsdf is blending into black while bekoming alpha-ed out.
- the material blendmode is "alpha blend". but other material blendmodes dont work aswell.
on 0.5 mixed, the holdout is half there, as expected, but transparent looks like color(0.5,0.5,0.5,0.5)
i assume, its internally blending to color(0,0,0,0) but the transparent needs (1,1,1,n) to stay invisible, and in this case should be at color(1,1,1,0.5) when 0.5 mixed.
(since is seems to not use the alpha information internaly and, if my assumption is correct, holdout just is alpha and doesnt need its own color data)
- so for the transition it might work correct if holdout takes rgb from the material to be mixed with.
i hope that helps somehow :)
