I added the support for volumes to PhotonGI. Now cache entries can be created and used on volumes too:
Very nice :)

Emission importance

The filesaver engine does not export importance in to scene file:

Code: Select all

scene.materials.<material name>.emission.importance
Is this bug or it's not supported any more?

Re: adventure golf hall

It's beautiful, but the grass will be soon gone under the roof and the wood on ground will rotten, there will be loads of dead birds around glass walls.

Re: PhotonGI cache

95% sure the hetero volume covers slow because the dense mesh has normals pointing in different directions and the triangles are very small. Upped the visibility.maxsamplecount so high it took 1 hour, no help there. Then i thought maybe photon path depth has to be higher than hetero volume max steps...

Re: PhotonGI cache

I probably need to go below 0.0001 radius and indirect.usagethresholdscale = 12000
Or maybe it's about the sampling efficiency, the small area takes about 90% render time, when i use linear random sampler with path-cpu, i see it's stuck there.

Re: PhotonGI cache

Does PhotonGi support only clear volume type, no hetero?

Re: PhotonGI cache

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. 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 :lol: ...

Re: PhotonGI cache

Just use a very high max. photon count :?: Okay, maybe together with very high value of that path.photongi.indirect.usagethresholdscale it will be fine. --------- EDIT Seems like when using maximum value, it continues shooting photons.

Re: PhotonGI cache

Can it be done so it will go over the bucket :D until the % is reached?

Re: PhotonGI cache

How do i use this:

Code: Select all

path.photongi.indirect.haltthreshold = 1.0
Every time it stops at:

Code: Select all

path.photongi.photon.maxcount
