So i am currently working on a FPS game for which i wanated a map but all the ones from scetchfab needed collision and rigid body which is very tiring when considered there are so many. Any way to make this process quicker and easier?
In the tutorials you may check the example First Person Shooter Starter Kit where collision and rigid body is added to each entity of an imported GLB. The script doing this is add-collider.js. You may adopt the script to your needs.
