[solved] Objects placed in editor without collision

Hey guys,
I'm currently trying to create a racetrack on Italy's airport but all the objects (.dae) I've placed with the editor do not collide with any vehicle - I can just drive through them.
Do I have to use another way to place them instead of drag & drop via the asset browser?
The wiki wasn't a source of help regarding collision issues but if I missed something, I'd be happy to read about that.

Thanks for your help in advance, appreciate it!

 

This is normal.
When you place a car inside a wall or something using World Editor, that car stays inside that object without colliding with that.
But if the cars do not collide with each other while driving, this is a problem in the game.

 

The car wasn't placed inside a wall, I've driven it into the objects I've spawned to illustrate the issue I'm having with the missing collision mesh.

Entities labeled as vehicles are working fine, I've placed about 200 barriers that collide with the vehicles. It's exclusively the .dae objects I've placed, like the gate and the concrete walls.

 

Please upload a video.

 

Have you tried restarting the game after doing this?

 

Yes, about 4 or 5 times yesterday. I just opened the game for the first time today and now it's working as it should, even new ones I placed collide with vehicles, but only after waiting for a couple minutes.

Yesterday I tried to:
- save the level after placing
- exit the editor before driving into objects
- reload the level via main menu
- restart the game

Everything without any change whatsoever, but coming back at it today, it's fine.
Very strange.

 

Are you doing 'Edit>Rebuild Collision' after placing objects?

 

Just tried it, that's what I was searching for! Thank you.
