Installing the Addon

These instructions will detail how to install the Blender Market version of the OpenFLIP addon. The latest version of the OpenFLIP installation file can be found in the Orders section of your Blender Market account.

Troubleshooting

When I start a simulation, I get an "Unable to load library: pyfluid" or "blender.exe - Bad Image" error. What do I do?

Some users have reported encountering these errors after clicking the Bake button. This error means that the addon was not able to load the fluid engine library. So far, 100% of these cases have been solved by reinstalling/updating graphics drivers (see issue #6). Please let us know if this fix does not work for you.

When uninstalling the addon, I get a "[WinError 5] Access is Denied" error. What do I do?

This error means that the fluid engine is in use and Blender is unable to remove it. Simply restart Blender and try again.
