There are 'intermittent' missing textures on all of the pipes for me (https://i.imgur.com/5BsCh6f.png). I have been scratching my head trying to figure out why they're sometimes missing but sometimes not and I can't figure it out.
I have found that the textures are more likely to be missing if I've loaded a different map before mannbase, and the textures always show up normal after a matsys reload like changing mat_specular or mat_phong.
I also have fps issues on this map, specifically bad fps when standing on 2nd looking towards mid or standing on mid looking towards 2nd, as if there's little to no occlusion going on between them. It's probably barely noticeable on non-toaster gpus though.
