Thank you so much!

I want to make zombies jump down from the roof into my map. If i remember correctly, you would do this with a prefab in WaW. I can't find the prefab in BO3 radiant. How do I get my zombies of the roof?
Thanks

Never mind, think i figured it out

Needed to expand the volume_fpstool zone.

Hey guys,

got the the same problem in my map... Seems to be a problem with the ground layer of the map.
I made a video (sorry for the bad quality) so you van see what happens when I walk away from the test map into my own map. https://www.youtube.com/watch?v=llPl-Sat8aw&feature=youtu.be

A friend of mine made a map too and has the same problem (different textures). Any suggestions?
Thanks!
