No I’m pretty sure PreciseConvexDecomposition means that when you have consistent holes in a flate brick that you can pass through them. Look I’m not building a castle here with floor unions. I’ve generated a simple flat brick union then I add holes to it. This object is simple it works for most of the holes then it randomly doesn’t work. My algorithm to merge overlapping floor unions is super efficient. It does it in two main steps. It’s like a chain of checking a part and the parts that it overlaps with those and the parts they overlap with. While not doing it unnessarily. I’d be happy to share the source code if you think that’s useful enough to use.
