Hi all, I was wondering if it was possible to access variables from a previous pass in the shader, i.e color of fragment or something along those lines. I want to have something that changes color over time after an event occurs. So if I can access a time delta plus a previous color then I can slowly modify it to a new state, is this possible? *Note this is my first time working with shaders, please excuse any stupid questions 😕 Thanks.
