Shader with glow effect and gradient material


I am developing an android game for uni. I want to create a circular object with a gradient texture from semi transparent (50%) to 0% transparent. But want it to be very low on draw calls etc. Can this be achieved using a texture on an object alone with maybe a baked light source at the base. It doesnt need to be animated just static would be great!

Im not sure where to begin. Any help would be great.




Download shadow gun sample project provided by madfinger games, which has few bunch of very well optimized shaders.
There is aslo similar shader which gives you the same effect which you are expecting.
