Hi I've been trying to import this Shadertoy, https://www.shadertoy.com/view/lsG3zK
I have it almost working, and the buffering is wired up correctly I hope - but the ripples / waves on my version dissipate almost immediately. I've attached a comparison screenshot. I'm wondering if differences in interpretation of GLSL code are the problem. It seems to be something to do with how the color / height values are being read / written.
Does anyone have any clues ? Thanks, Glenn.
