From ad6b0a468fac879b217209eb91b68e6bc143d6c4 Mon Sep 17 00:00:00 2001 From: Miikka Heikkinen Date: Mon, 20 Oct 2014 10:18:48 +0300 Subject: Document the issue with large surfaces and static scatters. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit OpenGL ES2 and/or 32bit environments can have relatively low maximum supported vertex counts per draw call, so large surfaces and static scatters may not get rendered.
