From 74fcc4c41fe547ea5fb8e23f25fc71b25f5afe96 Mon Sep 17 00:00:00 2001 From: Samuel Iglesias Gonsalvez Date: Tue, 27 Oct 2015 09:33:01 +0100 Subject: [PATCH] main: fix GL_MAX_NUM_ACTIVE_VARIABLES value for shader storage blocks MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The maximum number of active variables for shader storage blocks should take into account the specific rules for shader storage blocks, i.e. for an active shader storage block member declared as an array, an entry will be generated only for the first array element, regardless of its type.
