Thanks! This was helpful to me to learn that since sometimes I'll be rebuilding the whole pipeline from a vox file, it's probably best to figure out how to do that from the start.
You may also want to check out the textures in https://maxparata.itch.io/cyberpunkcity-monogon for the same pathing issue btw - I plan on purchasing them, and downloaded the free set for a test, and none of the textures came in.
