Minecraft version: 1.16.5
Modloader: Forge
Forge version: 36.2.4
Environment: Tested in singleplayer, but my modpack is intended for both singleplayer and multiplayer play

Mod name: Cycle Paintings (Forge) and Infernal Expansion
Mod version: 2.0 and 2.4.0, respectively

The Infernal Painting is a separate item from vanilla Paintings, crafted with 4 blaze rods, 4 sticks, and wool. I wanted to exclude these paintings and the item from my modpack, since I feel like the artwork doesn't fit a vanilla Minecraft style, and they look out of place next to the other paintings that are available. I can simply remove the crafting recipe via CraftTweaker, but unfortunately using Cycle Paintings still allows you to turn a regular painting into an Infernal Painting simply by right-clicking on it enough times.
In the meantime I suppose I can just use a resource pack to change the Infernal Painting's textures to be the same as some vanilla ones, but I hope that someday I can fully remove these paintings from my modpack entirely.

Thanks for opening the bug report and using the mod! I've added a blacklist feature via the config in version 2.1 of Cycle Paintings. By default the Infernal Expansion paintings are already excluded so you should be good to go by just updating!
