Blurred shadow reflection[solved]

Post by Noah_ »

I don't know if it is an error or if the caches are incorrectly configured

Full Hybrid Back/Forward path tracing - I don't like clamping - Bidir it's great but very slow - I have 4096 MiB de Vram and I want to cry.

I just tried with the three settings increased as shown attached. Not sure if all of them are needed, or to be increased that much...
Didn't take noticably longer to pre-compute the cache, but the probelm's gone and the rendering also clears with MUCH fewer samples.

Shadow does OK. It's caustic in reflection that's spilling over, so Caustic Light Cache / Lookup Radius of 1cm is your solution ;)
Also, use thickness/solidify your geo in future to prevent other issues - while modeling have physical correctness in mind 8-)
