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/mask/mask_draw.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'source/blender/editors/mask/mask_draw.c') diff --git a/source/blender/editors/mask/mask_draw.c b/source/blender/editors/mask/mask_draw.c index c60b673ec69..689a96a3dec 100644 --- a/source/blender/editors/mask/mask_draw.c +++ b/source/blender/editors/mask/mask_draw.c @@ -555,7 +555,7 @@ static void draw_masklays(const bContext *C, Mask *mask, const char draw_flag, c const int width, const int height) { 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); GPU_enable_program_point_size(); MaskLayer *masklay; -- cgit v1.2.3
