Is there a way to define the compound collision shapes in blender, aka muliple collision shapes per objects, say if you have a hammer, I would try to define that as a cylinder for the handle and a box for the head, but I can't seem to get anything but triangle meshes or a single collision shape in blender.

Yes, in the Game Buttons, you can select the bounds type. For the parent, you can select 'compound'. Use a recent Blender version.

There are some demos that give an example how to use this. Please see the 'gears' simulation in official Blender physics regressions files.

Ok, I was setting everything to be compound. But is it correct to say that you have to use multiple objects. I'm guessing the parent has to be an empty object that is compound, and all child objects are the different parts of the mesh with their own collision shapes? Also, I should mention I'm exporting to COLLADA 1.4 from blender and using that to convert to my own model format, but I just wanted to make sure the COLLADA exporter from blender does the compound physics shapes, even though I know the format supports it.

Hello Friends,

Hope you find this helpful

What do you mean by "Game Buttons"? is it properties view>physics tab>collision bound>compound?

I'm using version 2.67
