Mega Eye Shader is a shader with many options, think of it as a “build your own” eye shader, with all of the effects in here you can make mostly anything your heart desires,
This shader will come with a lot of effects to start with, counting 20+ unique effects for you to use off release of the “base shader”, with example materials made by me and some close friends.
This shader will also come with a shader optimizer script, since the shader will be very very big (even more so if you have DLC), this script will completely optimize your material and the shader before runtime to make upload times and performance as good as possible.
This “base shader” will have 7 unique shapes you can choose to use, shapes are as follows circle, cat pupil, cross, sharp cross, heart,snowflake,polygon. 
Note: Polygon will let you create mostly any geometric shape, triangle, squares, stars etc.
Are you planning on using this shader for commercial use? If so you do still need to buy the commercial use from my site. And you are only allowed to use the optimized versions of the shader you have made with the optimizer script, However you are aloud to use it as many times as you would like for new eyes etc.
This shader will have DLC in the future for effects that have been requested, each dlc “pack” will come with at least 3 new effects and will be inserted into your “base shader” on purchase of the DLC (this will not be coming for a while however, and dlc will be fairly cheap around 5-15 usd).
