No one can help me out ?

What do you mean by invisable...?

i had that happen once but dont know why, i may have selected a null point when i went to do the export. did you setup your scene root exactly like the one in the ironclad guide? assuming your using XSI. um, i dont know what else, im new to this stuff. can you see your textures in XSI on the model?

how big is the .xsi file? i am getting around 150-200 KB for a fighter sized model. the one i had the invisible thing with was around 15 but i think it was just a null.

Also when I convert from xsi to mesh I get "Ignoring unknown material",anything to do with the fact that my mesh is invisible ingame ?

To add ive being getting "Function not implemented in EXP version" when I try to export dotXSI tho the file is succefully exported,it's probably the cause of all this mess,anyone know why I get it ?

Please help me out,ive got alot of finished meshes ready for export but cant do it if they are invisible ingame.

I also tryed testing on a simple shape ,a cube and got the same results.

What do you mean by "finilise" ,do you mean have I done everything as it portrayed in the documentation files that come with forge tools or ?...

If it isnt to troubling could you please describe how to finilise the mesh ?

With my simple cube test I didnt even add texture to it,tho I still had some sort of "ignoring unknown material" when converting from xsi to mesh and still the model ingame was invisible.

Basicly this is how im trying to test my meshes ingame:
I made a mod file named "testmod" in mods file,copied gameinfo,textures and mesh into it and then renamed my mesh to one of the ships I could build at the start ,for exemple
Frigate_PsiScout.

And thanks again for everyone trying to help,I know that my trouble with modding may be trivial but this is my first time at modding.

Yes Idid freeze modeling and such... it's driving me nuts since I dont understand why my freaking mesh is invisible whatever I do!

When using convertxsi ,this is what I get:

Ignoring unknown material type <24>: DefaultLib.Scene_Material
Valid Material not found for PolygonList: DefaultLib.Scene_Material
Bounding Information Calculated - Radius:-1.00
Optimizing...
Pre-Optimization Vertex Count = 0
Post-Optimization Vertex Count = 0

what do you mean it isnt there ? ... the model is there and all,is there something else I need to do with it ?

When first reading this, it came to mind that triangles only show in one direction, with the solid side facing with counter-clockwise vertex order, but that can't be it, because when you do that, you simply see the back side through the invisible front side, and at least something shows up.

The mesh itself might be scaled too small to see, as if Normal data were used for the points, but that shouldn't happen.

Or the object might not be constructed from triangles, as SOASE only reads triangle data. If it's not that either, then that's my three guesses.

I am having the same problem. I tried a sins ship model converted to 3ds, opened it in xsi, added the textures as it stated in the documentation and exported as xsi. When I converted it to mesh again using convertxsi, no vertices are captured leaving me with no model / texture for the ship in game.
