If you have ever played Pixelmon with Immersive Engineering installed, you'll notice that almost every pixelmon will drop an Epic Shader Grabbag every once in a while, despite these bags usually being reserved as rare drops from bosses and such. This datapack allows you to sell these shader bags to Pixelmon shopkeepers for money.
Datapack made for Minecraft 1.16.5. Intended for in modpacks with Pixelmon and Immersive Engineering.
If you have any issues or recommendations, please leave them in the comments. However, I will not be responding to basic questions regarding how to use a datapack. There are plenty of resources for that available elsewhere.
