@AqeeAqee , pls make the ray casting extension have options for floor and ceiling by default (if it is, pls tell me how), pls make some form of easy directional object (like a chair or smth), and a way to enable 3d (like a wall) without collision. Until that happens, can anyone else tell me how to make a chair (with directional visual)?
