@sollaholla @SkylineGTRFreak Hey man, nice project you got here. Do u guys want to make props and use then with map-editor? My english is not very good, if I understood it right, do u need help to add collisions to the props, right?
Check this project I'm working on, maybe I can help in the collisions.
Watch the last video on the topic, all made with Map-Editor.
