Notes
For 4.2
- Crashes when using Metal was fixed by Michael Jones
- No updates on HIP-RT memory leak and OptiX OSL
- The previous idea of accepting known issues for the original 4.2 with a bug fix via driver or corrective release is open.
For 4.3
- Wehzhen and Alaska are looking into expanding test coverage
- Light linking and volume fix was re-iterated
- Fixes immediate studio requirements.
- Does not work correctly for nested volumes (which is similar in 4.1).
- More complete fix is in discussion.
- There is a report about self-intersecting volume objects
- Cycles does early exit from the volume
- Should be possible to consider such configuration as a “union” operation over the mesh parts
- Weizhen is looking into implementing stochastic noise paper
- CPU might not benefit from it that much, as the code is vectorized, so current focus is GPU
- There is measurable speedup, but the image looks more noisy
- Possibly required a better RNG state. The team will check on how to implement it offline.
- Bump mapping is wrong with stochastic noise
Various
- Intel is looking into implementing kernel compression as a DPC++ feature.
- The meeting went into a quick summary of papers from EGSR. There are some interesting ones, but maybe ot the highest priority.
