Revision 6a5d2f4 by Philipp Oeser (master) October 29, 2020, 08:27 (GMT) |
Fix blend_color_interpolate_byte returning wrong alpha in certain case When the combined alpha [the 'tmp' variable having the mixfactor applied already] - reached zero it was handled like a no-op (for the alpha as well) and just copied the first color. So e.g mixing 255/255/255/255 with 0/0/0/0 with a factor of 1.0 gave alpha of 255, which looks wrong. cases where tmp gets zero: src1 alpha:0 src2 alpha:whatever mixfactor 0.0 src1 alpha:whatever src2 alpha:0 mixfactor 1.0 src1 alpha:0 src2 alpha:0 mixfactor whatever Now set alpha to zero in that case. ref T81914 Maniphest Tasks: T81914 Differential Revision: https://developer.blender.org/D9357 |
