From 51f912786f420fcfa50a3d3f1b36794cb2714be2 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Sat, 2 Jul 2016 20:02:47 +1000 Subject: [PATCH] glsl: stop allocating memory for UBOs during linking MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This just stops counting and assigning a storage location for these uniforms, the count is only used to create the uniform storage. These uniform types don't use this storage.
