Having a rendering issue with this map in good ol' Spearmint... www.youtube.com/watch
Not sure what to make of it. I've posted the issue to Spearmint's git as well as on Reddit. If I find a fix I'll swing back to update.
zturtleman responded to my git issue:
It works correctly in the opengl2 renderer but not the default opengl1 renderer.
You can switch to the opengl2 renderer by opening the console by pressing shift+esc and then type com_renderer opengl2; vid_restart and press enter.
Again this is just for those of us running Spearmint.
