My radiant for world at war is a bit broken(I can't scroll and models don't show up in model browser all the time. How would I be able to use bo3 radiant to make world at war maps? I made a map with no textures or models using bo3 radiant black and it crashed in world at war radiant. It only had caulk texture

try reinstalling your mod tools. i just had to do it like 12 times to fix my tools cause i messed up ugx standalone install somehow. don't forget to install ugx patch an most importantly don't forget to click convert in launcher be for first use.
