From f2b844f59d86c5971118bfccb00ddc5a1b69797a Mon Sep 17 00:00:00 2001 From: Petr Sebor Date: Mon, 11 Nov 2013 16:19:00 -0700 Subject: meta: enable vertex attributes in the context of the newly created array object Otherwise, the function would enable generic vertex attributes 0 and 1 of the array object it does not own. This was causing crashes in Euro Truck Simulator 2, since the incorrectly enabled generic attribute 0 in the foreign context got precedence before vertex position attribute at later time, leading to NULL pointer dereference.
