How do I turn a concave model into little bits of convex meshes?

[Dlaor]

See title: Source doesn't accept concave collision models, and now I want to turn it into smaller meshes that are convex so I can use the complex collision mesh. How would I do this? I know there was a plugin for 3ds Max to do it, but it doesn't work for 3ds Max 9 :crying:

Also saw this, but didn't help: [url]http://www.rjcyberware.com/forums/showthread.php?t=128[/url]

Bump for justice. Is there really nobody who knows a plugin which does this?

I dont believe there is a plugin. One thought is you could makes boxes encompassing the concave areas and then doing a boolean-intersect
Then adding

$collisionmodel "blah blah blah" { $concave

Doesn't work the way I thought it would. It just removes most of the stuff. :\

Here's an example of what I want to archive.

In this example it could be done manually, but for more complex meshes I can't be bothered to do it...

Well, looks like this ain't possible. :crying:

Just break the parts up before you export your physics model, then attach the parts, set all smoothing groups to 1, and export as your phymodel.

Then when you're compiling, where you add the parameters for $mass, and $inertia and etc. Just add the parameter $concave.

You really just have to do it manually. You can't have more then 24 or so separate physics parts in a single model anyhow. If your model is so complex that you can't be bothered to make the parts yourself, it's probably gonna go over the limit anyway.

You probably could have already done it instead of trying so hard to find the easy way out.
