From 877dc0308f57bae3d4737fd28e56915428c1f261 Mon Sep 17 00:00:00 2001 From: Axel Davy Date: Sat, 26 Nov 2016 14:25:44 +0100 Subject: [PATCH] st/nine: Fix ff COLOR0 w component computation The computation was wrong. COLOR0's last component should be equal to the material diffuse w component. The behaviour was checked with a test app on Windows. Wine has the same behaviour.
