So it will not be totally off but also not so accurate in this case.
It is this stuff https://graphics.stanford.edu/papers/trd/
Code: Select all
intern/cycles/kernel/svm/svm_displace.h
ccl_device void svm_node_set_bump(KernelGlobals *kg, ShaderData *sd, float *stack, uint4 node)

Re: PhotonGI cache
I suspect the large span between light intensities (precision issue? ie. Sun&Sky VS Candle light) combined with "Automatic Lookup Radius" (too small or not enough photons?), since after values get balanced & Radius is set manually, debug result looks like:
Re: PhotonGI cache
could you post the final image with that kind of lighting setup?

Can you get your scene to crash with manual too small radius?kintuX wrote: ↑Mon Mar 11, 2019 1:01 pm I suspect the large span between light intensities (precision issue? ie.

I was able to use 0.001, but not well below this, and 0.01 radius is way better covered. In my case the auto radius is most likely tuning in too small radius when rendering high res like 6000 x 4500 pix, auto is crashing every time like manual radius 0.0001. Radius 0.01 already gives me map size of 8% with maximum number of photons.
Re: PhotonGI cache
It looks like instead of addition, new cache entries from different lightsources are replacing old ones.
Re: PhotonGI cache
I'm trying the scene but I get the right output out of the box:
Should I change something ?
