itch.io

Just drag in the house_colliders.fpx and match the position of the House.fbx. It has built in collisions so thats all you need to do for it to work

You import the asset into your scene then hold the asset node then press "create new scene" and it will show you a warning just press "new inherate (or something)" then save that new scene and then press a random object, then you will see a "mesh" button near the move (on mobile idk about pc). Press it then press the first one and change the sibling to something and you have your collision
