 Is there any method to get rid of the redness on the rocks? I got rid of it in waw but somehow I just can't remove it in bo3. Any help would be greatly appreciated 

Some models have a layer of texture for weather grime effects, and when you don't have a weathergrime_volume in your map the texture layer just appears red. It's very misleading because it looks like a missing reflection probe issue but it has nothing to do with the probes (as long as you have at least one in the area, at least).

Create a weathergrime volume and make sure you expand it to be large enough to contain all of the models which are appearing with a red texture.

By default the grime volume will create a snow effect but you can change its KVPs to different textures.
