Question by oliver-jones · Feb 27, 2017 at 08:15 PM · lightmapshadowlightmapping

Lightmapping - Noise

Hello,

I'm trying to get my head around all the options and settings for the Lightmapping Inspector, after baking, I get odd noise results on parts of my game:

alt text

The side edges of the road is incorrect, any idea what setting will fix/adjust this?

Thanks.

Are there any overlapping polygons in the UV maps for your road edges? It's possible that the lighting for one part of your model is being displayed in multiple locations due to overlapping UVs.

An easy way to ensure you don't have overlapping UVs is to use the Generate Lightmap UVs option in your Mesh Import Settings.
