Hello everyone !
I have a small probleme.
When i put an door in my map (in the radiant), and when i build my map, in the game the Models will not having collision.





So like you see in the screenshot, the selected object did not having collisions.
I realy need yout help.
Thanks

Collision depends on if the model supports it. There is a option in the Entity Info(Press N on keyboard with model selected) to enable collision if the model supports it called use_collmap.

If that doesn't work just add a brush with the clip texture around the door and link it to the door(Select door first then the brush and press W).

If the linking breaks the door just try to find a waw tutorial on making a clip for a door since I can't entirely remember how to do it.

I'd recommend getting into the habit of clipping all models with the clip tool textures. (clip, player_clip, and monster_clip) This helps you have more precision over what you want to be collidable, and it's great because most models it seems like don't have any sort of collision mesh this time around.

Thanks you !
it's working
