As it discovered(discovered for me) in topic:
http://www.ogre3d.org/phpBB2/viewtopic.php?t=14020

Today FPS models are one material, one submesh, and less bones possible, and around 1k tris.

So, does anybody knows how to control number of exporting submeshes in 3dmax?
Even when I convert my object to editable mesh it still can be exported with several submeshes!

You should attach all your objects, and then export.

You should search the forum, because it was discussed so many times.

A mesh will always be exported to different sub meshes if it has multiple materials. If you create a single material (a single texture applied to the entire mesh) then it should be exported as a single mesh.

Is that what you're doing and it's still exporting to multiple sub meshes?

Thanx for advice.

1.I created several teapots,boxes etc.
2. Attached them one to another (to obtain one model).
3. Converted it to editable mesh.
4. Applied material to it.
5. Exported it.



And obtained one mesh with several submeshes:


Maybe I do somethig wrong?

I want to add my question; does smoothing groups causes different sub-meshes ?

You should search the forum, because it was discussed so many times.

Sorry, I can't find anything that can be interpreted as answer to how to control number of exported submeshes. Can you post a link here?

I have made this simple experiment:

• Created simple box in 3dsmax.
  Converted it to editable mesh.
  Applied some simple material.
  Exported it.

And there are 6 sumbmeshesh!

sorry, I missunderstood your question from the start. Now it's clear to me which is your problem.

I guess you use the Octopus exporter
did you tried to use the ogre exporter?

I guess you use the Octopus exporter

Yes you right - now I'm using Octopus.

did you tried to use the ogre exporter?

Thanks, I'll try - maybe it will solve the problem.

I removed Octopus, installed Ogre exporter and repeated that experiment. So, the same sh#t.
Simple experiment. You can repeat it:

• Create simple box.
  Convert it to editable mesh.
  Apply material.
  And obtain 6 submeshe!

Does anybody have any guesses on this subject?

Have you tried simply to export the mesh without converting it to editable mesh? At least this works for me

But I failed.
I have 3DsMax7 and I downloaded exporterhere.
Are you sure that you have 1 submesh?

I'm using 3dsmax 6, and maybe an older version of the exporter.
Anyway I'll check this.

I have just found the same fu*** problem... in the xml appears that the exporter divides the cube in 6 submeshes, after creating a simple cube and putting a simple material... even without transforming it to editable mesh.

wtf??!?

I'm also having this problem. Has anyone found a solution?

[Edit]
Ok, I found the solution. In the ogrenew/Tools/3dsmaxExport/Docs directory there's an html file (index.html) that will tell you sortof how to do it. Essentially, instead of just creating a material and dragging it onto a box, you need to create a multimaterial that only has one submaterial, and assign all the faces of the box to that submaterial.

On a similar note, I've gotten some models from TurboSquid that had multiple material IDs assigned to various faces, and this causes multiple submeshes as well.
To fix this, go to the modifier tab, select faces, select all your faces, and assign a single material ID under the Surface Properties group.
