Hi Graham,
Now got another issue i don't understand.
Fragment shader failed to compile with the following errors:
ERROR: 0:30: error(#160) Cannot convert from: "4-component vector of vec4" to: "highp float"
ERROR: error(#273) 1 compilation errors. No code generated
float prevLum = texture(uPrevLuminanceTex, vec2(0.5));
I get the feeling the way ive coded things there may well be simular issues through all my shaders. Any chance i can just send you my Full deferred Opengl Renderer to check over. Obviously i dont want to post my work for the general public, so if you have an email i can send to if need be would be good. Cheers
James
