From cf3ce7322a9b6c1453869a369eba02f4fd077234 Mon Sep 17 00:00:00 2001 From: Antony Riakiotakis Date: Thu, 28 Aug 2014 16:40:38 +0200 Subject: Texture painting: Include explicit control for texturing: This commit introduces a painting mode option, available in the slots panel. The default value "Material" will create slots from the blender material, same as just merged from the paint branch. The new option "Image", will use an explicit image field that artists can use to select the image to paint on. This will should allow painting regardless of the renderer used or for use in modifiers. --- source/blender/editors/sculpt_paint/paint_image.c | 134 +++++++++++++++------- 1 file changed, 94 insertions(+), 40 deletions(-) (limited to 'source/blender/editors/sculpt_paint/paint_image.c') diff --git a/source/blender/editors/sculpt_paint/paint_image.c b/source/blender/editors/sculpt_paint/paint_image.c index ea6d56155cc..f596f330534 100644 --- a/source/blender/editors/sculpt_paint/paint_image.c +++ b/source/blender/editors/sculpt_paint/paint_image.c @@ -1363,41 +1363,87 @@ void paint_proj_mesh_data_ensure(bContext *C, Object *ob, wmOperator *op) Mesh *me;
