FLIP Fluids 1.6.5 is a small update that adds a hotfix to a bug related to compatibility between the sheeting effects feature and surface attributes.
Compatibility Notes:
FLIP Fluids 1.6.5 is officially supported in Blender 2.80 to Blender 3.5.
Blender 3.6: At this moment there are no known compatibility issues between this version of the FLIP Fluids addon and Blender 3.6, but this may change as Blender 3.6 develops.
Blender 4.0: At this moment there are no known compatibility issues between this version of the FLIP Fluids addon and Blender 4.0, but this may change as Blender 4.0 develops.
Bug Fix: Fixed issue where surface color, age, and viscosity attributes could be generated and displayed incorrectly if the sheeting effects feature was enabled.
This issue could cause fluid surface attributes to be generated as all black or partially black on random frames.
This issue was caused by a threading conflict within the simulator and can randomly affect users depending on system hardware and simulation set up.
If you were affected by this issue, re-baking the simulation will be required after updating to this version.
