Exporting collision mesh from 3ds Max

spectre1130

Hi, I'm a total noob at UDK, and I,m having the following problem. When I export, then Import to UDK, it tells me there is no collision model. I have exported 2 separate meshes from Max and gave them the proper naming conventions per my teacher, then tick off the 3 boxes in the Mesh options of the .ASE export menu. The window didn't look correct either in UDK, like faces were flipped or something.

Any glaring mistakes/oversights in my description giving away my problem, or do I need pics for this?

Thanks:\

just to double check the naming convention. you did export it as UCX_(name) right? can we see a screenshot of the mesh in UDK? and if you are doing it through UCX_collision then you only need to export as 1 .ASE .. they both need to be selected

Was just getting a screen shot ready

The default material is on there and I can't seem to tweek that material either. I run right through it as well. Do you need a mesh shot as well?

I did make a copy of the model and named it UCX_name, and exported both groups together as an .ASE. Here is a mesh shot. UDK immediately tells me there is no collision model. Also, as you can see the material looks all distorted and I can't tweek it in the editor.

Collision solved. I was grouping the separate pieces together instead of attaching as on mesh. Now I still have the issue of those front faces not showing the geo. It looks all weird and warbly. In unlit mode it just has a flat face.

Oniram

bear in mind that collision cant have holes or open faces. so if you just copied it from the mesh you would need to cap it off. to be honest best bet as far as that goes is use box collision. as far as the shading, looks like a smoothing group error.

So just make a box around it instead of copying the objects??

And how do I fix that smoothing? How is it done in UDK? The box collision is now fixed.

no need to make a collision mesh for it at all. in the static mesh editor you can set collision. fixing smoothing groups would probably be done in max/maya by custom setting smoothing groups (or hard edges in maya). Is this prop normal mapped/baked?

I made a quick video you might give a quick look at just to double check your collision needs

No, it is not baked, just a fairly low poly mesh. I think I know why the smoothing is like that. I am fixing it hopefully tonight after some lame political science homework.

Thanks for that video. I have bought one of your videos apparently in the past I as remember the voice. Good tips to go by. I was wondering about separate objects like that as well. I am actually needing to model something almost identical to that vendor stand. One question though is if my model is separate pieces like that, do i need to make the actual prop one attached mesh as well.
