Hello! I have several times problems with the volume grid, and "open vbd"...as in the attached image, the bounding box is perceptible, and the cloud of points touching one or several walls, causes a flat... How to solve this?

I guess the workaround here would be to avoid vdb's intersecting with other objects.

yes, I agree; but how?   you see, you get a Volume Grid, then in object you enter a vdb; where do you resize , inside the "volume grid", the point cloud?

I dsidn't understand, before; nothing intersect, it's just the ghost of the bounding box, when the point cloud intersect...

just another example... It's a pack buyed on art station, open vbd, and all the clouds included are "fighting" with the bounding box; same with a lot (not all) of free samples of vbd...  What's the problem???

Are you sure this vdb file is correctly generated? Usually the bounding box is larger than the actual effect.

Thanks,
Jan

I'm going to upload a file, but I've just noticed something: in the vbd folder, there were many files (0001-002-003-etc); if I delete all the files, leaving only the first one, the cloud installs correctly; so it would come from uploading the files to animate the
cloud?

Possibly, there is an import option to disable animated .vdb files.
