In the screenshot below I am firing my ships weapon at an enemy, the laser bolts impact particle has a point light attached that highlights the joins of the road pieces. Is there anything I can do stop this happening as it looks very ugly?
Are this all pixel lights?
If yes you can try to increase the pixel light Count in the Quality settings.
Unity will limit the number of pixel lights per object to conserve performance.
The least significant lights get culled away when rendering each mech if the max pixel light count is reached.
