From 3710c6110d65d3a604f7b419cd764cf5b9b98600 Mon Sep 17 00:00:00 2001 From: Dave Parks Date: Fri, 10 Feb 2012 20:04:19 -0600 Subject: SH-2908 Rework indexed texture rendering to use a uvec4 instead of a float for texture indices in the data stream. Also rework gl_FragColor overrides to not collide with some odd driver implementations. --- .../app_settings/shaders/class2/deferred/alphaF.glsl | 6 ++++-- .../shaders/class2/deferred/alphaNonIndexedF.glsl | 6 ++++-- .../class2/deferred/alphaNonIndexedNoColorF.glsl | 6 ++++-- .../shaders/class2/deferred/multiSpotLightF.glsl | 8 +++++--- .../shaders/class2/deferred/softenLightF.glsl | 8 +++++--- .../shaders/class2/deferred/spotLightF.glsl | 8 +++++--- .../shaders/class2/deferred/sunLightF.glsl | 18 ++++++++++-------- .../shaders/class2/deferred/sunLightSSAOF.glsl | 18 ++++++++++-------- 8 files changed, 47 insertions(+), 31 deletions(-) (limited to 'indra/newview/app_settings/shaders/class2/deferred') diff --git a/indra/newview/app_settings/shaders/class2/deferred/alphaF.glsl b/indra/newview/app_settings/shaders/class2/deferred/alphaF.glsl index 1179b212ae..373a6c157b 100644 --- a/indra/newview/app_settings/shaders/class2/deferred/alphaF.glsl +++ b/indra/newview/app_settings/shaders/class2/deferred/alphaF.glsl @@ -26,7 +26,9 @@ #extension GL_ARB_texture_rectangle : enable #ifdef DEFINE_GL_FRAGCOLOR -out vec4 gl_FragColor;
