Hello ! was playing with engine today (3.00.05) to find a good way for BF/LC or BF/BF renderings. btw i figured a huge difference when using LC retrace with BF/LC method. Impressive. here’s the question : if i leave the BF subdivs to default 8 and raise the global multiplier to, let’s say, 8, i …

8 BF subdivs = 64 rays times 8 = 512 rays max 64 BF subdivs = 4096 rays times 1 = 4096 rays max. Best regards, Vlado

doh ! got it ! :wink: multiplication opposed to square… sounds very logical. Huge thanks, Vlado !

Sounds like it’s same behavior for irrmap subdivs. if you want 100 Hsph subdivs then you need to put 71 with globl mult = 2. (71² * 2 = 10000 approx). And not 50, wich is bad value is a bad value. Right ? was same in older Vray versions (hsph) ?

thanks for fast answer. I have some things to rewrite now :wink:

[image] Material Override Exclude Is that also for material and light subdivisions? ie: 8 reflect subdivs = 64 rays times 8 = 512 rays max 64 reflect subdivs = 4096 rays times 1 = 4096 rays max. ? Yes - it’s the same for Light, GI, Material, Fog subdivisions throughout your scene. Subdivs…

Don’t forget its also divided by your maximum AA samples and controlled by adaptive amount in dmc settings…

stupid bruteforce question... global mult very different then increasing BF subdivs..
