Invisible Barbwire after reimport!

[Spaehling]

Hello guys,

since a week i got a problem. i need to export a fence and reimport it to udk. that worked fine with the fence-pole. but the fence self makes lots of troubles.

i dont know why. but my material is like the stock material. and in the stock mesh there are much more material groups inside. i work with maya. i know forum is really hard to help, so if someone has a plan he could maybe add me in steam or so.

would be nice if someone can help me.

1. Reimported Mesh 2. Reimported Mesh + Material 3. Stock Mesh

Spoiler!

Is the problem that the barbwire mesh won't accept the material you are applying? I know sometimes this is caused by not triangulating the mesh before you export from Maya.

hey, no i dont think so. the material gets accpeted an then it turn invisible. but i check that out.

edit: hey, the planars are triangulized.

Check that your material is double sided. On planar meshes it will only be visible from one side if it isn't.

How about the UV map on the fence part? It's easy to accidentally alter or create unwanted UV channels in Maya... you can also run into trouble with meshes exported from the SDK, as they typically have multiple UV sets.

You can view the different channels with the 'UV Set Editor' window in Maya - on version 2010 that's found under the 'Create UVs' menu.

hey, the uvmap is correct. the texture fits correct without opacity mask or transparent stuff. i didnt give you a lot information about stuff i figured out, but its really hard sometimes to explain it. because i tried a lot stuff.

but i have tried it with a PNG as a Texture and that worked. i need to rework the png a bit and need to test it with lightmap, but if it works i think this is a solution. (thanks GrimReality)

but i still wonder, why it didnt work with the stock material

I GOT IT! And it looks like the stock Mesh!

Its a bit hard to explain. But the problem was all the time, that my Texture hasnt a alpha map. i extract the stock material a while a go with umodel.

with that texture it works. i try to give a better explaning if someone wants to have.
