Ligths like movies proyector

I´m looking to generate with lights a simulation of movies proyector of a cimena.

i inlcude two spot lights, in diferent color but its doesn´t work beautiful at all.

Thanks

Dear Juan,

First of all you have to write a detailed Question. I assume you wanna create an effect like visible lightbeams of a movie projector, like this

I’d recommend using a 2D-Sprite that is illuminated.
