hey, i've had this problem as well, but i slept on it and almost forgot what it meant.. I THINK it means that you have a material assigned to an object in which said material doesn't exist. Are you trying to apply multiple materials to a single object? if you are, try this:

add an edit mesh modifier, and use the element select tool. select all the parts you want, then go to the edit dropdown menu at the top, and invert the selection, then delete it. once you've done that, you'll have the part that you plan to add a different material to (such as decals), and then go into your material editor. create a multi-sub material, name it, and make sure it only contains ONE (1) sub-material. then choose what bitmap the sub-material should have, and then in the little boxes in the material editor under where it shows the spheres, you press the checkered box with the lightbulb so you'd be able to see it once it's applied. next, click on the pull-down menu where the material is labeled, and click on the uppermost item, and upon doing so the mat editor should take you back to the multi-subobject list where there's only 1 sub object. then, click on it's representative sphere in the mat editor, and drag it on the polygons you have left as described above. this SHOULD work, as i had the same problem before if you need some more help, lemme know.

ok...do you mind describing how you do this? the process, and everything else i might have done?

" Then I pick my texture after clicking the box next to diffuse.
5. I highlight my entire model and click the "Assign material to selection" button.
6. I click the "Show map in viewport" button.
And that's pretty much about it."

i believe that at #5, you need to do this:

then click on the highlighted portion to bring you to this:

which then you procede to highlight the model, then apply. try this, and see if it works. the way you described it to me is that you still had the standard material selected when you applied it.

i believe thats because there's a material that doesn't have a name or label. are all of your geometry objects linked to a frame node?

ok. save your file, i just found something on the web that may work:

"editable mesh, then once your object is that get rid of all the smoothing groups and use a multi-sub material type, set the selection id's for the faces and apply the selection id acording to the multi-sub id and apply it. that happens cause usually the id's have like a name (no name(1)) and like when you assign the multi-sub it creates the group with out the multi-sub i dont believe it will export i donno thats how i fix it at least " from: http://www.modhalo.net/index.php?/topic/23370-bluestreak-jms-exporter/

i honestly cannot remember how exactly i fixed this, but i know it had to do with the name of a material. lemme know if that worked.

holy. crap. i've never seen THAT before... i don't know what to tell you about that thing. try reexporting the file, deleting the older one and the doing it again. it seems like this is a smaller problem on the web, because i just google searched it, and barely came up with any hits..

the name error is because SOMETHING... i don't know what. but SOMETHING in there (it's either the material, or an object with the material) has a wrong label. try resseting ALL of the materials, compile, (it should give you an error), then apply only 1 sub-object material yadayada.

the name, my bad. it has to do with the material's name applied to it. the name error is because the material that you've applied (as stupid as it sounds) somewhere, has no name...

i have a question for you though, seeing as how i can't really get much help by pm'ing people about this:

i have no idea why it's doing this:

everything works in 3ds, i've replicated most of the properties from the old n'pelican, yet it still is kinda wierd.
