Case 690662 Screenshot of phenomenon in Scene View, using the Baked render filter: You can see the point light, the black spots on the table, and the black wall, with some buggy noise on the black wall. Here is the work-around I used... Please post here if it helps you. 1) Go to Window -> Lighting -> "All" Tab 2) Click on the buggy problem object in the Scene 3) Look at the Preview Pane in the Lighting Window. Choose "Baked Intensity" from the Preview Pane display type. 4) Observe the UV positions: And for the desk and TV: If you look at the UVs for the Desk+TV, and the UVs for the black wall, you can see they overlap. We must separate them. Maybe there are better ways to do this than my method. If you find a better method, please share with everyone. 1) Go to Project View, then Create->Lightmap Parameters 2) In the Lightmap Parameters Inspector, change the following: a) System Tag to any number other than -1 b) Baked Tag to any number other than -1 3) Select the biggest overlapping object. In my case, it was the black wall. 4) View the object in the Lighting Window (NOT the Inspector window) 5) Change the Advanced Parameters to your newly created Lightmap Parameters. Observe: 6) Observe the Preview Pane. It should not longer have the old overlapping UV objects. This is because we changed the Baked Tag and System Tag for its Lightmap Parameters. 7) Also, Observe that UV positions for the Wall. It's WAYYY outside of the Baked Intensity texture map. The UVs are only showing maybe... 2 sections... But it should be somewhere closer to 5 or 6 sections. We must scale it down. 8) Change the Scale in Lightmap value to something smaller than 1. Make it so the UVs fit within the Baked Intensity texture: This... seems... to have fixed the problem for me. If it works for you, please post below. If you find an easier way, please post below.
