Ok you need to add first code to your shader list and call it ReflectionShader01 (or any other name but you will then need to add it to Lua part. Then you can call this shader with Lua (second code here) with any action you create (at begin of scene or whatever you use). Also you will need to have your mask png linkded correctly so game knows where shader is appled on the screen. I will attach one I am using for my game but you can make any shape of it... Also other picture is used if you want to create waves effect alike water. My code if for clear non moving mirror tho. But you can play with settings to customize as you wish :)#ifdef GL_ES
