Well the title says it all. It crashes when I try to open it up in ZE.
Here are some pictures. I think it is because of all the polymeshes but I don't know any way to fix this.

Rendered Wireframe

What is it meant to be? Is it just a static prop? How did you set up the ODF?

just a little holdup thing for inside a cave.

this is the odf. I also have a lowrez and shadow volume. do these need to be added?

Export a simple textured cube and see if it causes a problem.

a simple box works.

Double check every object in your scene to see if it falls within the guidelines set by the developer of ZETools. Use the process of elimination to find any possibly corrupt object/s in your scene (ex: remove collision mesh from hierarchy and export). Try merging objects and see if it helps.

I removed the collision and re-exported and opened it up in ZE.
It allowed me to put down the object after it took several minutes to load the model up.
I munged and the munger stops responding at the part where it tries to build the models collision.
The munge log is this: And there are no command posts for me to spawn at anymore:

BF2 Log:

Edit: Process of elimination did it.
It was the sv_underpass. I don't know why it made the munger stop working.

Edit2: Well it is working in-game but I can't add anything else in ZE but it because it takes up all the space. The shadowvolume HAS to be in the game and so does a bunch of other stuff.
Needless to say it still is technically crashing ZE. It takes 13 minutes for it to load into it(ZE).

Your model looks fairly simple, if it takes 13 minutes to load that in ZE then something is definitely wrong there. I don't know what your modeling workflow is like but I would just remodel it with fewer parts and see if it works better for you.
Several pieces of your model look identical (legs), you could just create one full leg section then UV it, duplicate and translate.

so what you're saying is to remodel the whole thing from a cube and just duplicate, sub-divide, and move points so it is all one msh?
And any help on UV-ing would help. The only way I know how to texture is by Render/Texture/Image/new from file/ my.tga/planar (xy)(yz)(xz)

I quote from the tutorial I used to learn, by rhoffman:

"Now, under the Texture Projection section click the new button, and then click cubic. ( for this demonstration cubic should work best, planarxy would also work. Some choices are self explanatory. Others are not. If you have a very complex item then you would select UniqueUV’s ( polymesh ).
Now if you didn’t merge the objects then the texture would be applied to each box independently.
. From the left tool pane under the Get section is material, select it then select Phong. A properties box will now show up. Under the diffuse section you will see a little plug icon to the right of color. Click it, then image. The properties window will change. Under the image section click the new button, then from file. Browse to your selected file"

You may also want to consider checking if the model crashes in-game as well. Do this by changing the ZE geometry to something harmless, but leaving the in-game geometry as your desired model.

if it is able to load in ZE it works in my map.

Use the check button on the exporter and make sure you have the newest version installed
If theres something displayed in the Check button (i think its called Check sel (check selection)) so select your model check it and post what the exporter shows you

Well here it is.

underpass(my model) in pictures And the texture section:

What I have done that I think might be the problem is cube modeling. I took a cube and added sides and walls and leg things all from one cube. Do I have to keep every polygon four/five sided?

Yikes, all those errors will definitely crash ZE/the game. Let fix them!

First, a note. Your polygon's faces should never be more than 4 sided. Some of yours are 6 or 8 and as much as 16 sided.

Onto the fixing, select your model, and on the left hand side in XSI go to modify > Poly. Mesh > triangulate. Your model will now have triangles throughout the entire thing, removing the 68 polygons with bad faces. It may look odd, but it shouldn't affect your UV's too much.

Now, you should always freeze your model before export. To do this, select your model, go to the top of XSI, select edit > Operator > Freeze operator stack. That will remove the texture support error. On that note, make sure you freeze transforms and have all your objects a child of a null before export. If you need a complete guide to exporting with ZETools, I can write one.

Happy modelling, from a fellow modeller.

A guide would be nice if you want to do one that can be downloadable. Thank you I understand now. Beautiful solved problem. works wonders.
