I want to ask about Point Interpolation Feature in PBR.
What i mean:
Yes. This look unclean. But in many cases, with photon hit-point interpolation we can get very fast smooth GI result instead of using huge amount of sharp PBR photon points.
Please advice me: this is possible with PBR ?
i mean smooth interpolated Photon Mapping ? (when photon hits look like light areas with smooth edges, instead of small sharp points)
by default using the photon maps (via the indirect light) does a raytraced final gather step against the photon map. this means you don't get that soft ‘interpolated’ look by default.
if you want to get that soft look, you can set your indirect light to ‘direct global photon map’ and disable ‘photon map stores direct lighting’
