Blender version support (4.3)
Version 1.75 update notes;
Char (HHP):
Added IK/FK switch in the preview animation box. There is no snapping IK to FK yet but that is planned
Physics / Proxies (HHP):
Added "Physics framerate multiplier Inside the Physics box > show advanced options. It will set the physics speed multiplier based on your scene fps. It works on selected meshes so you wouldn't accidentally change physics for entire scene. This is due to HHP physics being a baseline of 60fps and some people animate at 24 or 30. This will fix physics speeds to your framerate
EXPERIMENTAL - Creator Tools
Create HHP Mask: Mask selected vertices in edit mode by creating an HHP property for "Customize (HHP) > Misc"
This addon has an auto update feature. But you can always click the check for update button and update it yourself if you don't want to wait for the auto update and you want the features now. Be sure to restart Blender after the update completes (It usually takes 2 seconds or less)
