my problem is the inside of the voxel. i made a hole inside a mountain and the lenght of the hole is
three voxels long. the problem exists between the secound and the third voxel. when i go into the cave suddenly the hole disappears and i can see the water under the mountain. if i went through
this hole the rest of the cave appears.
i tried to make a vis area around the cave but this doesn´t worked.
i attached two pictures for you to show my problem
