Blender 5.0: Physics¶

Point Caches¶

Support for LZO (lite) and LZMA (heavy) compressed disk caches has been dropped in favor of ZSTD compression. (#141461, #144356)

New caches tend to be smaller than either of previous options, and are faster to write/read. UI option for compression mode was removed; caches are always compressed now.

Blender will warn users when loading older .blend files using these removed compression methods. End users will need to delete these old caches and rebake them. Loading unsupported point caches and trying to play them back will simply do nothing or produce glitched playback.

Smoke & Fire¶

The amount of vorticity no longer varies with the time scale and time step. This bug fix changes the simulation results when the time scale or step have been changed from the default, and vorticity then needs to be manually changed to match results from older Blender versions. (PR#141053)
