WARNING

Many users reported that their is a bug with mesh generation like on this picture:

I don't know yet where is the bug, but I found that it occurs when a parameter is changed in the node "Mesh With Voxel ..."

I believe there is a bug with ComfyUI caching system, but I'm not sure.

The only solution for the moment, is to restart ComfyUI.
