Question by Lebro_Design · Sep 28, 2017 at 03:01 PM · unity 5lightmappingupgradelighting bug

Strange light behavior in Enlighten for Unity 4 project imported in Unity 5

I have imported my Unity 4 project in Unity 5 (or 2017) and some models have strange lighting behavior after baking the light maps, these models are the exact same prefab positioned next to each other and the three fridges on the left are much lighter than the 3 on the right.

Same model next to each other with different lighting behavior

This behavior happens all over my scene and when I duplicate the lighter models and replace the darker ones the new duplicated model turns darker as well. This model is using the legacy diffuse shader but I also see this happening using the standard shader. Does anyone know what might cause this issue?

My settings for the mesh, material, lights and lighting are: Settings

Usually, this is caused by reflection/light probes that have some of the items in range, but not all. I don't see any widgets for those on your screenshot, but could there be one nearby offscreen?

Yes there is a reflection probe (no light probes though as everything is static), but the problem also occurred without the reflection probe (I added it just to see whether it solved the issue) and the probe is encompassing the entire scene.

But I was thinking the same thing as it really seems location based, switching the two models around results in the three fridges on the left being lighter still.
