From 7e05e4c3883fd3fdc863b580701e2546e4d37772 Mon Sep 17 00:00:00 2001 From: Axel Davy Date: Sat, 19 Mar 2016 19:55:24 +0100 Subject: [PATCH] r600: 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.
