3 years ago The latest experimental version of the FLIP Fluids addon (v9.0.9.23) no longer functions in the latest Blender 3.0 Alpha build (July 22, 2021, 64bb49fa4e3c) or in the latest Cycles-X build.
These issues will need to be fixed before the Blender 3.0 release in August 2021 (exact date TBA). Update: the Blender 3.0 release has been delayed until late October.

KeyError: 'advanced'Immediate render crash
If attempting to render an already baked cache (animation or frame), Blender will immediately crash with an EXCEPTION ACCESS VIOLATION error. This crash seems to occur during frame load before rendering begins.

Blender 3.0 is in early development and is set to release on August 25, 2021. At the time of this writing, we have not extensively tested Blender 3.0 and would consider this version not yet officially supported with the FLIP Fluids addon.
Official support will be added at a later date. Typically, the compatibility changes between Blender versions after Blender 2.80 are very small - if there even are any changes needed.
At the moment, there are no known issues when using Blender 3.0 with the FLIP Fluids addon version 1.0.9b or the latest experimental version. The Blender 3.0 Cycles-X branch also seems to work after some brief testing.
This issue thread will be used to track issues related to the FLIP Fluids addon and Blender Version 3.0.
