yay..took few hours just to get this working: Render a whole camera view with one shader.
\nIt should be simple, but the documents wont give any examples: Camera.RenderWithShader <\/a><\/p>\n

Main image is showing vertex-depth-shader seen with camera (its modified version from one of these unity replacement shaders<\/a>)<\/p>\n

Next..
\n– How to use camera shaders to make some more fake shadows? or ambient occlusion? or this kind of screen water effect<\/a>? (with unity indie..)
\n(I dont know..going to play around with the camera shader a bit..)<\/p>\n

—<\/p>\n

Update#1<\/h3>\n

Well this is interesting, the fake river shader works quite nicely as camera shader.
\nAnd a problem..fragment shaders wont work with camera??<\/p>\n
