Collision model

[Le0]

I'm trying to make a collision model for my mesh and I did everything I needed, created the collision model with simple basic meshes and then named it UCX_meshname then I exported both the collision and the model out of 3ds max, but when I import it only the model is imported correctly but no collision is added to it (it says NO COLLISION MODEL!).

How must I do it?

• Make sure that you have a convex shape
• Make sure that your collision mesh and your static mesh have the same pivot point
• If you applied a smoothing group to your collision mesh (don't know why you would do it though ), make sure that all the faces have the same smoothing group or simply remove the smoothing group(s)
• Watch for any open gaps in your geometry
• Double check the name of your SM and your CM

You can post a screenshot if you want!

Make sure they are both selected at the same time before export. And choose "Export Selected".

Thanks guys, I'll give it a try soon

[Le0]

I've tried all you guys suggested and still no chances.

And the collision model isn't just a plane? Are you exporting as .ase or .fbx?

[Le0]

Can I use planes for collision? I thought I had to use basic shapes (cube, sphere etc..) I export as FBX

Any convex shape will do the job. I don't know what were missing here but you could always use a blocking volume if your collision mesh doesn't work :S

[Le0]

yeah of course but since this is a mesh I'd like to use a lot I'd prefer for it to have collision added automatically. I'll give it a try with just a plane again.

Also good to see you're still around Olivier, what are you up to these days? Still modelling random stuff?

Busy with school, it's my third night in a row with less than 2 hours of sleep. Working on a map atm. I'll have to complete the airplane I promised you a few months ago one day D;

Oh you're making a map for RO2? Or is that for another game? Good luck with school! And don't worry too much about that plane, it's very nice of you to do it of course but I'm kinda rethinking of where I wanna go with this level design thing I'm not very good at

Forced to make it on the UDK, which isn't that bad when you think about is since it's the same engine. But it would be nice if my teacher could somehow allow me to use the RO2 sdk :X

EDIT: Have you tried the automatic collision that is generated by the game engine? It works pretty well with objects that are not complex (especially with box-shaped SM).

hey guys, i've got now the same problem.

maybe this could help. i try this out:

thanks Spaehling, I'll give it a try with ASE
