This tag tells the game whether the voxel data of this object should be cached or not. Unlike in case of DisableShadowCache, not disabling the caching does not in most, if not all cases incur any drawing or visual problems. Developers' original intention seems to have been to reduce memory consumption caused by caching animated voxels. However, it should be noted that disabling voxel caching can cause rather drastic performance drop with large and especially animated voxels if substantial amounts of them are on screen at once, as they have to be constantly redrawn without being able to speed it up by using cached data.
