There is already dev compiling version of flywheel and create for 1.19.2 forge at least.
As well as oculus.

Really want to try it in my modpack, since I am getting massive lags with trains.

Strange. You can reach with that to the dev (Discord: NanoLive#4206). Just say that you are the dev of that mod. He might help you, I guess.

Almost done. But there is a question.

When I added create and oculus (only these two) and then placed a block that rendered by flywheel in game, the game crashed.

There is new flywheel build out, you might give it a try.

Create and Flywheel packed jar in jar is officially out.

The latest version has been uploaded. 😎
