[Max] General Discussion / Re: Path Tracing always as Secondary GI Solver
« on: 2025-07-09, 08:24:12 »Speaking about bias, how about MSI? I was quite shocked another day to find how much light it could prevent to reach the areas that doesn't even seem that much occluded. Attached are comparison of default MSI 20 vs MSI 0 (off). Of course i would not recommend to turn MSI off in your scenes, because you'll surely get a ton of fireflies and much longer render times, but it might be useful to try adjust it in some darker interiors and see if you like what you see. Does anyone remember the old MSI 200 rule? :]
By the way, new firefly filter does pretty amazing job at removing excessive fireflies caused by turned off MSI (see the last attached example).
Really interesting test, MSI - 0 really brings out the translucency of the leaves, yet it seems the firefly filter knocks that back again despite there not really being many fireflies on the leaves
