Hello, so i've seen that if you run on certains blocks (gas concrete for example) the running particles would be of the purple checkered missing block.
Now I don't if it's an incompatibility with optifine or dynamic surrounding but it's there.

Hi, not sure, which version are you running on?

latest one on 1.16.5 (1.1.14)

Okay, I put it on the list to check, cheers,-

Oky, just double checked, the particles are as normal with v1.1.18/forge 1.18.1-39.0.5. There are also no special aspects that can be modified in the mod code. Can you update and double check again? Cheers,!
