Takua Render (CPU + GPU VCM renderer)

[Ondra]

But may i ask again, why doesn't it supports all available features if it "contain" progressive pathtracing by default? :))

because the other light transport parts make it incompatible with a lot of features. It is not just matter of adding the 2 results from two methods in photoshop, that would produce very bad results. the algorithms are interconnected on a very deep level, you cannot separate them and make one of them compute all fakes/extensions and the other just caustics

VCM is better that Pathtracer ... faster , no light leaks , no fireflies , no needs to gi caching , better performance ...

because VCM and develop panel are gone from 1.6 ... corona is only pathtracer, not vcm ...

VCM is still there - System tab in Render setup, System Settings button, enable devel / debug mode, then the Performance tab shows the same settings as previous versions, including the Bidir/VCM Render engine.

Hahaa sorry, i thought the blending method is just as simple as lightmix method :D
Thanx for the explanations

[Ondra]

blending just framebuffers would be horribly inefficient because 50% of a firefly is still a firefly. You need to blend sampling probabilities as well. The math gets much hairier there

whoaa it sounds so painful and creepy, I just can advise you to not forgetting the bugsprays when start to rework VCM in the future :D
