I see black screen when i put an item of this mod in my hand.
I use Optifine I9, Minecraft 1.19.2

Hi, I suspect optifine hooks into the overlay rendering in a problematic way. As a context, I use the standard Minecraft rendering methods for showing the blockstate.

Track the issue down, which mode version do you have, and are you on fabric or forge?

Cheers,-

Oky, redstonepen-1.19.2-forge-1.2.20.jar is in approval. Optifine seems to be the friend of all modders due to the brilliant compatibility ;).
