I need to get what TIM file format info I've figured out into the Wiki, but I'm just swamped with RL issues and other projects. I REALLY need to finish the TIM file stuff.

Why not email me your .TIM file, I'll paw through it and see if I can find anything funky? I'm not sure what I can do to help at this point, but another set of eyes never hurts.

I can't check that file out until the weekend, I'm traveling for work and my laptop doesn't have T3 on it. (It can't even run T2). But I can view the .TIM file stuff.

Send me your file, and I'll check the other one this weekend.

OK, weird stuff;

1.) Thank you, you pointed out a bug in TIMtoE. I was reading a field wrong, which made me lose the rest of the file, which is why there was no collision object for the STMstairsspiralC-rail2.TIM when it was converted to 3DS.
2.) The collision model for that object is just a post at the top, nothing else. I'm not sure how you can avoid jumping off the stairs, maybe the navmesh keeps you from getting off. I don't know yet.
3.) Your collision model for the spiral stairs looks really good. But it might be too complex for T3. I haven't seen any complex models for the collision object yet, so maybe it has a limit somewhere.
4.) I'll send you the re-constructed 3DS model for the rail so you can look at it.
5.) I'll update and post my TIMtoE program this weekend, and incorporate the fix into the full TIM <> 3DS program - as soon as I get time to get back to it.

Possible, I guess. I'll do some more checking...

WOO HOO! Breakthrough.

For artist generated collision to work, it must remain convex. BUT, you can have multiple meshes making up the collision of a single static mesh. The hierarchy is put together as mesntioned earlier, you just make all the collision objects children of the collision dummy elements (Collision and High Detail). The pivot points of the collsion objects must also perfectly match that of the static mesh. So, the method I used is as follows:

1. Take your mesh and run the collision maker script.
2. Delete the mesh that is created.
3. Build an assemblage of convex meshes that approximate the shape of the original object.
4. Make their pivot points have the same postition and rotation as that of the static mesh.
5.Make them children of the High Detail object that you can find in the scene object list.

The resulting hierarchy should look like this:
Static Mesh
----Collision
------High Detail
--------Object1
--------Object2
--------etc...
