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/mesh/editmesh_knife.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'source/blender/editors/mesh/editmesh_knife.c') diff --git a/source/blender/editors/mesh/editmesh_knife.c b/source/blender/editors/mesh/editmesh_knife.c index 5d5e54edf56..671a868947e 100644 --- a/source/blender/editors/mesh/editmesh_knife.c +++ b/source/blender/editors/mesh/editmesh_knife.c @@ -1116,7 +1116,7 @@ static void knifetool_draw(const bContext *C, ARegion *UNUSED(ar), void *arg) int i; glEnable(GL_BLEND); - 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); /* draw any snapped verts first */ immUniformColor4ubv(kcd->colors.point_a); -- cgit v1.2.3
