From 618bc6c67954f80b3c0c0332f44648b3187c23ca Mon Sep 17 00:00:00 2001 From: Brecht Van Lommel Date: Wed, 14 Feb 2018 01:01:29 +0100 Subject: GPU: use alpha blend that works for drawing to transparent buffer. It's unlikely to ever be intentional to square the source alpha, as happens with glBlendFunc, so this changes the blending throughout the code. --- source/blender/editors/animation/anim_channels_defines.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'source/blender/editors/animation/anim_channels_defines.c') diff --git a/source/blender/editors/animation/anim_channels_defines.c b/source/blender/editors/animation/anim_channels_defines.c index 9fb30dc8066..87fe002e536 100644 --- a/source/blender/editors/animation/anim_channels_defines.c +++ b/source/blender/editors/animation/anim_channels_defines.c @@ -3827,7 +3827,7 @@ void ANIM_channel_draw(bAnimContext *ac, bAnimListElem *ale, float yminc, float selected = 0; /* set blending again, as may not be set in previous step */ - glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); + glBlendFuncSeparate(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE, GL_ONE_MINUS_SRC_ALPHA); glEnable(GL_BLEND); /* step 1) draw backdrop ........................................... */ -- cgit v1.2.3
