From b6fa72d3c4d02527f6d118eadc9ba1ac48a297f5 Mon Sep 17 00:00:00 2001 From: Graham Linden Date: Mon, 3 Dec 2018 15:33:15 -0800 Subject: SL-10055 Modify handling of directional light to prefer sun when it is up but use moon dir/color when it is alone in the sky. Modify handling of shader in shaders to get some shadowing of ambient and nighttime shadowing. --- .../shaders/class2/deferred/softenLightF.glsl | 192 ++++++++++----------- .../shaders/class2/deferred/sunLightF.glsl | 14 +- .../shaders/class2/deferred/sunLightSSAOF.glsl | 12 +- 3 files changed, 115 insertions(+), 103 deletions(-) (limited to 'indra/newview/app_settings/shaders/class2/deferred') diff --git a/indra/newview/app_settings/shaders/class2/deferred/softenLightF.glsl b/indra/newview/app_settings/shaders/class2/deferred/softenLightF.glsl index 541122fb18..184ac13b27 100644 --- a/indra/newview/app_settings/shaders/class2/deferred/softenLightF.glsl +++ b/indra/newview/app_settings/shaders/class2/deferred/softenLightF.glsl @@ -39,7 +39,7 @@ uniform sampler2DRect normalMap;
