This update will change the way custom properties are displayed a little bit, and will also show masks if any is present. Shapekeys/materials/mask options are separated for more clarity.
You can add custom properties to outfit meshes or "Extras" meshes yourself following these naming rules :
- RGB node : "UI - " + whatever
- Value node : "UI Float - " + whatever [goes from 0 to 1]
- Value node used as a boolean : "UI Bool - " + whatever
- Shapekey : "UI - " + whatever
- Mask : "UI - " + whatever
