   Did you setup the 2nd UV channel for lighting? You'd probably also get better results from a road shaped mesh that is nicely segmented. Though sometimes you just get wacky errors. I did a modular sidewalk that would have odd lighting errors whenever it so desired.

   So I'm working on a level for my portfolio, and it's a down town area (my hometown) and I decided to go with tileable plains. Now the problem I'm having is that they aren't receiving lighting information correctly as you can see in this pic.…

   I'm using max 2010. Do I just change the Map Channel to 2? ***Update*** So I tried that, and re-exported. I also adjusted the collision mesh slightly as there was a touch of overhang. When I re-imported and rebuilt the lighting, it seems to have fixed it. Was I supposed to do anything with this second UV channel in the…

   the udk's generation will create the for the uv's and the uv channel you just have to specify what channel # it is. (really simple and self explanatory when you start playing with it) However, I second vig's decree of normally you add the second channel in your native app before exporting. While the UDK can generate decent…

   Normally you add a second channel in whatever modeling app you're using, before you export. If you want something a little more specific I need to know what app you're using... I think UDK can also auto generate the UV's for you but it might require the 2nd UV channel to already be there.

   Yes hahaha, i've built my lighting, and i've tried it with, and without lightmass. Now, the weird thing is, if I move my light to a new position, the seams dissapear, and everythings lit properly, but once it's built again, it all goes to hell. Maybe it's because i'm using a plane? And it's shadowing weird because it's an…

   actually, thanks because that was the one part I wasn't able to figure out with the help of Grimm_Wrecking. Problem solved guys, thanks a million, and sorry about making the thread in the wrong spot, I never noticed the UDK part before.

Sorry to sound rude as this has been addressed a few times on this site and is very easy to find info on with just a little bit of reading and about 10 minutes of…
