Hey Yall, 

I got a new problem. Im getting some irregular surface lighting on my metal panels for one of my assets. Anybody got any ideas what issues maybe causes this ugly surface lighting. I'm still getting used to surface normals and smoothing groups.

My guess is to check your smoothing groups -- I don't know much about them until Jason showed me some last night. I can't tell what your geometry is doing in this image, but I would adjust your smoothing groups in Max and use the lighting in there as a reference, then export and replace your unreal model file to test in engine. Adjust the smoothing groups by selecting logical groups (based on geometry) of subcomponents ie; edges, verts, etc, assign smoothing groups as appropriate, then evaluate. Keep in mind this is a guess as I really don't know much about them myself but I think that's prolly your problem :)

Have you baked lighting yet?  In preview mode lighting isn't exactly accurate.

Also smoothing groups and checking your topology are important as well.
