I think this error is caused by a bug in one of the shaders itself. I think gl_FrontMaterial.emission is a vec4, and your shader compiler is complaining about a type mismatch. Can you change line 79 of /home/syd/FG/fgdata/Shaders/ubershader-gbuffer.frag from float emission = dot( gl_FrontLightModelProduct.sceneColor.rgb + gl_FrontMaterial.emission, to float emission = dot( gl_FrontLightModelProduct.sceneColor.rgb + gl_FrontMaterial.emission.rgb, and see if the error goes away? (You may see subsequent errors from other shaders that also make the same statement) -Stuart ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
