Livery making is a slow process which isn’t something new. Forza Horizon 5’s livery editor when moving a shape is quite slow compared to Forza Motorsport 7’s. The grid size is different too though, but movement on its own in Fm7 is worth going back for if your in a rush.

I think it would help immensely if we had an option to change movement speeds in the menus for Forza Horizon 5 or Future Horizon titles. Similar to the speed options you have in the eventlab.
