Odd model lighting

[Tophius]

Hi all. I appear to be having a problem with my model in game. Nothing I've tried so far has worked in alleviating the issue. Doubled sided faces are disabled. I have recalculated normals many times, and then checked them myself. I have applied "Scale and Rotation to Obdata" many times as well. There's nothing strange in the material settings for the exporter.




This only occurs when shaders are enabled. It might look like an issue with the model's normals but it acts much like a shadow being cast on the model. Other players are able to see this as well. Any help is appreciated!

Oh, in case it wasn't too obvious, the problem is the bright patches on the model.

That certainly looks like a normal problem but the geometry might be wonky too. Can you PM me the model so I can check it out?

[Tophius]

Sent ya a PM.

The normals and geometry are fine. I applied all modifiers, applied loc, rot, and scale and exported. Works fine.

I did exactly what you said, still getting the weird lighting. Strangely enough it only appears when the object is at certain angles, irrespective to the viewer's or the sun's position.



Have you tried picking it up (assuming it's an item in your screen) and moving around?

Update: looks like this is entirely affected by the model's scale. If I double the model's size, the issue is made worse by a huge factor (I'm talking the entire vehicle glows). If I halve it, the problem is gone completely. Doing this either through the exporter or within blender itself seems to produce the same effect, and again, applying scale to ObData does nothing. Unfortunately though, making the car smaller is obviously not a possibility for me, so I'm still stumped!

EDIT: Fixed! Turns out this is caused be scaling too generously in object mode (what isn't?). To fix it, I scaled everything down in object mode first, then went into edit mode and scaled each object back up individually. Not sure whether the old "add a cube, join the meshes and delete cube" method would have worked though.

Well, thanks for the help anyway!

Try making the materials not reflective. That might mess something up.
