FloorGen Tools

They should

I didn't test 2020 floorgenerator but it should work.
You need floorgenerator plugin for 2020 of course. They released it.

We did some tests of DropToSlate in 2020, it was good.

Actually all scripts should work fine in 2020 and if you'll have some problems I will try to solve them, and refund if I fail :)

For those who compares Floorgenerator plugin and FloorGen Tools

It's not about Floorgenerator vs this script

Floorgenerator is a cool plugin and this script is a helper for it, a booster, with additional features that Floorgenerator doesn't have because of its modifier nature.

Try to create tiles on things like stairs or walls with free Floorgenerator version and you'll understand the reason I developed this script.

Free version is absolutely the same as paid, except of more patterns. So you can test how this modifier behaves on walls. And it's not a fault because it's a... floor generator, not walls or tiles generator :)

Please read script requirements

This script requires installed floorgenerator plugin actually. Floorgenerator cant create tiles on multiple surfaces in one click. So download free floorgenerator version and try it.
Paid version is just more patterns.
