LaglessHair | automatic hair hiding during posing | Blender 2.8

Automatically detect and hide particle systems on objects while in pose mode in order to remove lag and boost performance. 

This script works with linked files!

Change the extension to .py if it got converted to .txt during download. Open preferences in Blender 2.8, under addons, click Install and locate the file. Check the checkbox and save preferences so the tool is always there for you :)

Under the Active Tool panel you will find the controls for Lagless Hair (3rd graphic). Everything is enabled by default. Entering pose mode or playing the animation will hide all hair.

note:

Create the option to hide hair in object mode while the mesh is being moved. Create a button to manually hide hair when you don't want it.

Update history:

v1_6 - Suppressing Warnings: Added an exception for cases when there are no collections, added an exception for no active objects

v1_5 - works with linked objects now, UI panel moved to Active Tools so it's always accessible, works with multiple objects with hair systems properly, removed redundant code, added KeyError catcher to stop the script from breaking
