I have simulated static meshes and a pawn with a static mesh that is simulated (the pawn is moved with forces). Both the simulated static meshes placed in the world and my pawn have constraints limited to a YZ plane (2D movement). This all works fine but as soon as any of these go into a physic field (chaos field) which simulates wind blowing in a direction, the constraints break. Suddenly, they can rotate and move on all axis.
If I set the simulation > ‘default degrees of freedom’ in project settings to ‘YZ plane’, it does work but that’s not what I want to do as I will need to be able to rotate/move on all axis later.
