Blocky artifacts in various render passes when rendering overlapping VDB volumes in Cycles

@mod_moder I'd like to test with more VDBs first before I make one

Blocky artifacts in various render passes when rendering overlapping VDB volumes in Cycles

Hello just an update here, I've looked into some production scenes where this is a problem with VDB overlaps once they get to a certain complexity eg. the main wdas cloud but not wdas_sixteeth if…

Cycles: volume sampling improvements

I went on a refactor spree, and got things to compile at least (untested!): https://projects.blender.org/boberfly/cycles/src/branch/feature/ratio-tracking

I'll be force-pushing to this here…

Cycles: volume sampling improvements

Hi all,

Just wanted to chime in that I am attempting to graft this patch that @kevindietrich adapted from Tangent/Sergen as there is a situation where some production scenes that I'm working on…

Materials linked to 'Object' cause increased memory usage in Cycles

Adding this here as it might be related: https://archive.blender.org/developer/differential/0017/0017158/index.html TLDR; Cycles assigns shaders to geometry not object so if a unique shader is…

Cycles : Massive OSL performance deficit compared to SVM using AcesCG studio profile

Hi @lichtwerk

Simpler than that, I was just outlining that I am using GafferCycles with very similar versions and that I was able to demonstrate the issue in Blender as well (it's much worse…

Improve Cycles OSL nodes interface

Something I noticed is that I ran into an assert, there's a bitmask on the amount of input plugs to a max of uint64_t (64 plugs) in Cycles.

Yes I have made an OSL node that uses just under 100…

Cycles : Massive OSL performance deficit compared to SVM using AcesCG studio profile

Ok I am getting to the bottom of this, Gaffer recently has got a studio-config for AcesCG set, eg. OCIO="ocio://studio-config-v1.0.0_aces-v1.3_ocio-v2.1"

So I am testing Blender with this…
