i followed the basic modelling with xsi tutorial using mod tools and my doorway object doesnt work when i export the scene using crosswalk into a .xsi file it still has the .exp tho it says doorway.exp.xsi could that be the problem?

exporting creates another "scene" in the xsi format, your old scene wont be changed if you should mean that?!
maybe you didnt change the name when exporting it, but that doesnt matter, because .xsi is the last extensions the .exp wont be more than a part ofthe scenes name

can some1 download my scene plz and get it working into a msh and it actually work ingame? as i was converting the rocket (from the tut) into an msh it found some error and crashed it. then i tried putting it in bfbuilder and it crashed it. just post the working rocket as an msh here plz. thx

wouldnt it be better to search for the problem instead of asking somebody to export it for you?
that isnt meant rudely

ok

EDIT
ive looked 4 like 20 mins. and havent rly found much. i made a new object (a jet) very basic since im new 2 mod tools and i exported it and it didnt show up in ZE. here's the steps i did.

1) i created a null and renamed it 2 dummyroot
2) i made the model and put the objects under dummyroot
3) i duplicated it and named that collision and merged them
4) then i saved it and exported it as an xsi model
5) then i used mshex thing from repsharpshooter
6) then i tried 2 put it in ze and nothing shows up

wat am i doing wrong or not doing???

Patience young Padewan, oh wait you're Jango you are one of the bad guys.

Anyway on to your problem, when you are doing the crosswalk export are you branch selecting the Dummyroot (middle click on the word dummyroot) and you are selecting 6.0 text as the type of file to export.

i did the tut again with the doorwall thing and tested it and still nothing shows up

ive made the jet much more detailed now. its supposed 2 be an av8b harrier. is this pretty good so far 4 a beginner? can some1 download this model plz and check if anything needs 2 be changed 2 get it working in swbf? ive looked like uve said.

That does look rather nice.

Is it textured?

thx. its not done yet. gotta add missiles and rocket launchers 2 wings and work on the back of it. idk much bout getting a texture 2 fit it. i guess ill look 4 some tuts. i just wish i could get my models 2 work in swbf! how do i create a cockpit 4 1st person view?

I don't know much about the cockpit, you'd probably need a hardpoint of some sort.

You didn't texture it? Models need to be textured before they can be exported. Exporting an untextured model will result in a crash.

wat about in the basic modeling tut? it showed this untextured rocket ingame.

That tutorial assumes use of the Pandemic XSI addon, not RepSharpshooter's MshEx. If you use the latter, it must have a texture.

Mav beat me to it. Yes, MshEx is unable to handle untextured things.

well then that might be my problem when im using the mshex from repsharpshooter do i need 2 put the tga file (my texture) in the mshex folder along with my xsi file when i convert it?

No, you do not.

so in mod tools im supposed 2 rename the null as dummyroot and put all my objects under it including collision and lowrez right?

i textured it, i merged it, i gave it collision, i gave it lowrez, the mshex took like 2-4 mins. and still when i place it in ZE nothing shows up! this is very frustrating! wat am i doing wrong?!?! r there any tuts 4 modeling with xsi mod tools and not foundation? im pretty sure i did everything right.

Please don't doublepost.

MshEx has some special requirements for exporting - everything you export with MshEx must have a texture. It would be best right now for you to just create a model - no lowrez, no collision, just a model - put it under dummyroot, and then export paying careful attention to MshEx's instructions.

Note that your model will still have collision; models without collision have collision generated for them automatically by VisualMunge.

As a further slightly off-topic note, you can create a model without a collision by giving it an msh.option with the line -nocollision.
