From a221f40dbb0d63f6b5478a25742ef3e0a3317a59 Mon Sep 17 00:00:00 2001 From: Axel Davy Date: Sun, 3 Apr 2016 21:47:11 +0200 Subject: [PATCH] r600g: Change default behaviour for undefined COLOR0 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit d3d 9 needs COLOR0 to be 1.0 on all channels when undefined. 0.0 for the others is fine. GL behaviour is undefined.
