Hey there,
I'm trying to get a prop ingame (before this i've only done weapons). But I'm kinda confused about how to make a collision. So is there a basic tutorial on how to add a collision geometry? Thank's.

If your prop is one object, i make a really small cube, put it in the object, merge them, and rename it collision and hide. If it's multiple objects, just merge them all, same thing.

What if I wanted it for the walls of my maze?

Edit: A few more questions:

Does this have to be done in XSI?

And is merge the same thing as combining them (I'm trying to figure out if this can be done in Maya)?

Heard of the duplicate tool?

Just duplicate you model, name it collision, and hide it.

I use duplicate quite a lot... I just thought that collision couldn't be textured.

That makes things much easier. Thanks a bunch!

It can be, but it saves space if it's not, so open the collision, and delete it's texture clusters.

What if I have a hi-polygon model ?

Like how high?

Depending on the model, the collision sometimes needs to be even higher poly.

But I don't think the collision is rendered ingame, so I don't think it would cause any major problems.

That's really simple and can be done in Maya meaning that my maze is done too!

Though I still have one quick question, couldn't you just rename the original object before the duplication collision and then not hide it?

Oh, and one more. If my object is like 5000 polys and I give it collision, I won't be able to use meshex anymore will I?

Uh no collision needs to be a seperate object from the original model... If I'm understanding you right. You also wouldn't want them both named collision.

Well last I heard, MshEx doesn't export collision, so there would be no point to you adding collision in scene, just to export with MshEx. Ask someone to export it for you.

How could I add a collision and still use meshex ??

You can't.
MshEx will only export the visible meshes. I think someone said they got collision working with MsheEx somehow, but I don't remember who or if it was really so.
Since MshEx doesn't export the collision, the game itself must make a collision surface.
Just ask someone to export for you.

Thank's .

No, what I mean is lets say you make something. Then without duplicating it name it collision, its still the only object in your scene. You don't hide in and then you export it. Would that object now have collision?

I honestly don't know what would happen then.

Good idea Woner . I'll try that, and if that doesn't work, I'll have someone else export for me. Thank's .

Erm... maybe this is just my lack of modeling experience... but doesn't visualmunge automatically create a collision geometry if the model doesn't have one?

No, it doesn't. ZE does if you check off build accurate collision geometry when opening the map, though.

Ah... well, I've never made a collision geometry for any of my models (as MeshEx can't export them, at least the second edition can't) and they've all had collisions in game. VM just says "blah_blah_blah has no collision geometry (this will be slow)"
