Problem with models lighting

HashBrownHamish · Mar 2015

So i'm having trouble getting my low_poly scabard looking correct. I have tried quite a few things but still the lighting is "off" to say the least.

I've tried -manually setting up smoothing groups,
-mirroring UV's in trouble areas to see if it is caused by normals.
-Remodelling the low poly from nothing to try and get through any problems i didn't notice.

Here is the model in two different light settings just to show off the issue.

What're you rendering in and if you're using a normal map can you post that up as well?

Yep, and what program are you adjusting the model in, if different from the rendering program? If you're exporting to a 3d format, which one? Some formats don't support smoothing groups well (.3ds) and some others might mess up vertex normals (.obj).

Ah ok sorry should have pointed out.

So the render is done in marmoset, the result is the same with or without the normal map. And the file format is .Obj

But what 3d software is the model made in?

If 3ds max, do a Reset Xform, Collapse, add an Edit Normals modifier and reset all the normals, collapse to Editable Poly, then re-setup your smoothing groups. Make sure the OBJ exporter is exporting the Smoothing Groups properly (http://help.autodesk.com/view/3DSMAX/2015/ENU/?guid=GUID-437051A1-983B-4B6A-80C4-D2FA43B7393D)

What does it look like in your 3d app?

Make sure you have export normals enabled if exporting from max.

Make sure to set the tangent space (in object properties) in TB2 to match where the normal map was baked.

Ok so i tried everything i was recommended and the model is looking much nicer (got to re-bake with better settings but that is for another day).

Only issue now is this lighting mess which won't go away x)

EDIT: All *FIXED*

I'm going to guess it's the normals of the mesh.

in 3dsMax, throw an Edit Normals on and check out the normals in that problem area. Use the move gizmo to adjust their pointing angle - that, or that need to be split, which can be done in the Edit Normal modifier (called break, will split the normals based on the selection type)

In Maya, it's the Edit Normal Tool. Same idea as above.
