car headligths, streetlight projection of light on ground?

Unity Engine
1

Currently all my cars and streetlights project their light onto the ground below them using a projector based on a modified version of the shader/material of the simple blob shadow solution included in the standard assets.

As I understand it, projectors are not that good for performance, but how else could this be done or at least optimized?

I appreciate any idea on this!

Thanks!

You can replace the street lights with a lightmap and the car’s lights with a transparent mesh. I’d use the projector only for the player’s car.
