Triangles turn black one by one upon getting closer

[Leathe]

Hey,
Im creating some fan art for a game called "smite", I've loaded the game models into udk. Everything works fine, thought whenever i get close to a game model it turns black.

I've done some research on internet and couldnt find a solution to my problem. I also tried different versions of UDK and all seem to be having this problem.
Some object do not do this, though the mayority do. I've tried looking at the settings of those object and found nothing different.

I hope you guys can help me figure this out.

Greetings

Have you rebuild the lightning?
Is the lightmap correct?

It is using precomputed visibility, im trying to disable that and rebuilding the lighting.
How would i go about checking the lightmaps?

Here you can read about lightmaps: http://www.worldofleveldesign.com/ca...-lightmaps.php

I've taken one object apart, rebuild the lighting without the precomputed visibilty and checked the lightmaps and both were fine(no overlaying things etc).

Is it possible that you can upload one of those meshes somewhere so that I can take a look at them?

Hmm, I wonder if for some reason you have a very strange LOD difference and it is causing an issue with lighting somehow. I'm no artist and haven't personally worked with any dramatic LODs (only small weapon LODs), but if there is a drastic change I'm wondering if it can effect lighting.

I have took a look at the meshes. I never saw anything like this. This black stuff also appears in the material editor so:

- either there is something wrong with the material (but I dont know what could be wrong)
- you could also try to create a 2nd uv channel in your 3d programm (normally you can do that in UDK, but somehow I cant do that with your meshes)
- try to make a texture with alpha channel so that you can "delete" the black background (probably this is the problem)
