I am getting white lines between the terraintexture tiles as I may already told you when telling you about frac Happily there is the new _repeat feature which is going to allow for awsome terrain shaders
Other than that, it is of course very nice :P I especially like your presentation and the documentation. The mega particles refraction pass seems a little strange to me. I had the idea to do the refract through deferred shading, but I haven´t really done it yet, but will do so pretty soon
