shiney seams.. UDK
polycounter lvl 8
hey guys am new to all this so this may be a simple problem.
whats causing the shiney seams in this floor panel? the texture tiles fine in max etc but when added to udk its coming out like below. help would be great

quick rundown on how todo that mate?
any other reason these seams would be like this?
Can you post a shot of it in Max, one with a blank material and one with the normal map applied?

with normal and mat

in udk

And is this before or after you baked your lighting?
normal map.

does the whole model need to be in 1 smoothing group or no smoothing group atall?
As for the smoothing groups, its dependent on how you go about generating your normal maps and what results you're trying to get. Rather than me trying to explain this haphazardly, try reading through this.I would probably break this up into different smoothing groups because of the hard egdes. I would also probably not even model in the indentations you currently have on the low poly.
Edit: nm, already implied in the smoothing group suggestion
heres some images of it now..
before light build

after light build

the lightmap uv set

driving me crazy this lol
Have you tried just as a test to let unrealed generate the lightmap uvs and see what happens?
arghhh!
My fix was not optimal but it worked out for me. I snaped the modular sections and welded them together in Max and then exported the larger segments. With the smoothing issues taken care of in max they baked cleanly in UDK.
Like I said, not the best way to work, but it solved my problem.
I hope it helps.
i tryed to split the 2nd set at same point as the first but that didnt help it.. the first uv set is defo effecting the 2nd set.. just dont know how or why...
ill post my uvs later on when i get time to at the comp.

The only other possibility that I can think of is that you are overlapping your first UVs "Up and down" which is a no-no, and instead should only mirror "Left-to-Right".
You will have to rebake your normals and all that as well, but the UVs MUST be horizontal when overlapping UVs in UDK.

Scroll down to "Mirroring UVs"
I would actually do a rebake anyway. Try tiling the high poly and welding them together before baking. That will make sure the normals on the edge of your model are pointing in the correct direction.
ill have a bash again at this tonight from the start taken the stuff into account and see how it goes
I'm not sure what caused it, but the smoothing in the mesh seemed to be all jacked up. Even with all the smoothing groups removed, the mesh remained smooth.
I fixed it by first resetting the Xform and the running the STL Check modifier on it. Then I redid the smoothing groups and exported it back to UDK.
This is before baking the lighting, so any artifacts you get after baking from this point on are most likely from the light maps. You'll have to rebake your normal maps after fixing the smoothing groups as well.
If you tried the fix I posted and removed all the smoothing groups, there shouldn't be any more of the errors you were experiencing earlier.
i removed a line from the center of the panel and welded it into the side so its just 1 big bit.. and its away now
still faint seems where modules join but there not to bad
