my map is quite big and i have used alot of textures to add details. now i tried adding some bo1 weapons but after adding 1 weapon i got this error ''Exceeded Limit of 2400 Image Assets'' so i decided to delete some images from my map in radient and it worked. However when i tried adding 3rd weapon i got the error again .
How do i get rid of this ''Exceeded Limit of 2400 Image Assets'' without deleting stuff from my map. HELP!

You have to many textures and models in your map you'll have to get rid of some. Never had this error but I know that it's a major pain.
