Move stars to just this side of the sky some to reduce parallax. Remove decodeNormF and uses of decode_normal in favor of unified use of getNorm (try to help the Intel HD x000 compiler learn to link correctly). --- indra/newview/app_settings/shaders/class3/deferred/sunLightF.glsl | 1 - 1 file changed, 1 deletion(-) (limited to 'indra/newview/app_settings/shaders/class3/deferred/sunLightF.glsl') diff --git a/indra/newview/app_settings/shaders/class3/deferred/sunLightF.glsl b/indra/newview/app_settings/shaders/class3/deferred/sunLightF.glsl index e230ebb71c..112b498c90 100644 --- a/indra/newview/app_settings/shaders/class3/deferred/sunLightF.glsl +++ b/indra/newview/app_settings/shaders/class3/deferred/sunLightF.glsl @@ -38,7 +38,6 @@ out vec4 frag_color; // Inputs VARYING vec2 vary_fragcoord; -vec3 decode_normal (vec2 enc); vec4 getPosition(vec2 pos_screen); vec3 getNorm(vec2 pos_screen); -- cgit v1.2.3
