I actually was interested in this exactly for all the optimization features that are now included on Ultimate Voxel Optimizer by Nat (itch.io)
It feels a little... "scummy?" (strong word but english is not my first language, can't think of other words lol) to buy this, get canceled and basically move all the features I wanted to a new product that now costs 4$.
I think it would be nice if you gave the few people that have keys for this keys to Ultimate Voxel Optimizer by Nat (itch.io) too Nat.
