Polymost : severe HRP drawing issue
Introduced by b6740a7b (doesn't compile) or e67e5391. When using the HRP + Polymost renderer, many sprites are not drawn, partly based on the viewing angle. (Polymer is OK.) Setting "r_models 0" 'repairs' that, but messes up the former models. (I had rather expected r_hightile to make a difference.) Blatant example map (convenient start point): RUSHtest.map. Logfile: RUSHtest.log. Screenshots (Polymer, Polymost, Polymost with r_models 0):
