ItemPhysic version: v1.4.15_mc1.16.5
CreativeCore version: v2.0.10_mc1.16.4
OptiFine version: HD U G6 pre12
Forge version: 1.16.5-36.0.1

When OptiFine is present in the instance, none of the config values in itemphysic-client.json are respected.
However, custom rendering is still used - the item spins at the default speed, etc.

Working on HD U G6, nvm.
