EDIT: Good intentions, sadly I just noticed its only for up to engine 4.22, so thats a decision you’d have to make if that engine version is suffiicient for your needs.No idea what author plans are . There are other voxel plugins but they are more expensive.
BTW, as your design grows, don’t shy away from voxel’s for underground structures as that is a option I’m considering heavily , bc while doors or portals are fine , sometimes having a seamless transition underground maintains a vision for realism better. YMMV just something to ponder for later.UE4 has no voxels built in atm to work with so you’d have to buy-in for that , tho there are ‘free’ options long as you aren’t going for online gameplay &/or need other features:
I am not the author , as I was referred to this myself from someone on these forums.
