path.photongi.indirect.haltthreshold = 1.0
Code: Select all
path.photongi.photon.maxcount
It is a number between 0.0 and 1.0 where:Fox wrote: ↑Wed Mar 13, 2019 8:33 pm How do i use this:Code: Select all

Okay, maybe together with very high value of that path.photongi.indirect.usagethresholdscale
Code: Select all

Can such kind of things be automated ?Dade wrote: ↑Wed Mar 13, 2019 4:24 pmThe look up radius must be smaller of half of the door depth. So specify the radius by hand to a value like 1cm. To balance the very small radius you have also to scale back the brute force parameter (so from 6 to something like 6 * 15 = 90). And you get the correct result:epilectrolytics wrote: ↑Wed Mar 13, 2019 2:25 pm Did I do something wrong modeling the door or is it a PGI issue?

You can not use 2^32 as input otherwise 32bit integers will overflow at first computation, use 2^31 if you really need to use an absurdly high value.Fox wrote: ↑Wed Mar 13, 2019 11:40 pm EDIT
Seems like when using maximum value, it continues shooting photons.Code: Select all

Looks like it must have gone 3'rd or 4'th time back to 0 with 2^32 photons. 1'st time map size was 0.1%, now it's 0.8% and memory use is 123GB
