So I went to compile my map so I could test it and it said map with no materials, can somebody help?

This error is sometimes caused by not having the correct things ticked in Launcher when compiling.

For mapname.map have ticked only:

Compile BSP
Compile Lights
Connect Paths
Compile Reflections
Build Fastfiles




For mapname_patch.map have ticked only:

Build Fastfiles

I was JUST about to make a post about this(I still might have to).
When I compile my (non-patch) mapname with BSP, Lights, Paths, Reflections, and FastFiles, Everything works just fine
But when I compile my mapname_patch(ONLY using FastFiles), I get this error.
I looked it up and found two posts about this:
https://www.ugx-mods.com/forum/help-desk/10/error-map-with-no-materials/4008/  and  https://zombiemodding.com/index.php?topic=13898.0
Neither of them helps me even though I do EXACTLY what it says.
