hey, the map was working fine and then all of a sudden i loaded back in and everything has a purple hue to it...is there anything i can do about that..?

@AnEvilTurnip Try entering 'mat_specular 0' in console.

i played the map yesterday and it was fine, i played today and some props were invisible

so im using some of the props from the addons extension down at the bottom of spawn list sidebar to do a custom rp with my friend. i spent a long time on this and i was hoping it would work. everything was fine except he could only see "some" of the props, the rest showed up as errors and this has stumped and frustrated me. He does have a old pc but it should still be able to run every single prop. for some tech nerd who see's this please help

NavMesh??
