I have bought Nitrous Butterfly Office Level Kit, and was trying to learn how to use it.
I build a simple corridor and some rooms, then I tried putting Point Lights to illuminate the interiors.
However as I kept adding lights, some strange artifact became apparent, where the room and corridor prefab snap together.
You can clearly see that there are lines between each prefab, the light does not blend smoothly.
I tried lowering intensity or range, but even at the lowest setting intensity 0.1 the lines are still visible, and the light do not blend smoothly.
This appears to be an issue with the lightmaps in your scene. You should either
a. Ensure all level pieces are marked as lightmap static and re-bake the scene.
OR
b. If you don’t want light maps then ensure there are no existing lightmaps are built for the scene by clearing them in the light map window.
thank you for your answer. I was not using and lightmap, as I was just testing out the kit. However your advice will be precious once I start using it in a real project.
I found that the Render mode of the lights affects the problem I was having. By default my lights were set as Auto, so I has seeing this effect. Changing the Render Mode to Important fixed it.
Just wanted to chime in and mention that this also happens in the Universal Render Pipeline, and can’t be fixed by setting Render Mode to Important as mentioned above.
