Need help - M1 garand

sipher3325

Hey i've been working on this M1 garand and im having a few issues. I used a symmetry modifier for some of it to save on uv space but for the light map im guessing im going to have to unwrap it again to get rid of the seam. Im also having this other problem on the receiver and I can't quite figure out what it is.

No normals right?

no there is

Have you reversed the green channel? UDK wants it inverted If I remember right. As for the UV seam along the stock I think it'd have to be moved to a less seen place if it's meant for an fps view. Whenever you have a UV shell edge across a visible area it's going to give you shading problems
Best option is to try and hide them in crevices, folds and the like.

Ya im wondering if i just stitch the uvs together in the lightmap then ill be ok?

sipher3325

nope...just did a quick test and it doesn't fix the problem. now I have to repack and start over.

Why do you need a lightmap for a model that is going to be dynamic?

sipher3325

good point...either way i need to fix it.

little update on my m1 garand

Oh I definitely know that problem, ran into it before. Unfortunately, UDK doesn't read mirrored geo very well at all; it calculates the spectacularity in different directions for the two shells and causes the terrible seams you're having. Try viewing the model in unlit mode or turn of the static mesh's specular to diagnose the problem.

UDN has a snippit about fixing the problem by not having them overlapping, but rather shifted over in the UV space. I think I've tried that before and it didn't work for me, but I could be mistaken and if so, that's definitely the easiest route to try. The alternative is to remap it because UDK can cause you trouble with mirroring.

Ya the new model is completely remapped.
