Is there a way to make custom maps for BO1 zombies in plutonium?

[CeenSeen]

I've seen lots of tutorials on to making custom maps for WAW, but since I've mainly wanted to play BO1, and plutonium now supports custom BO1 maps, is there a way to make custom BO1 zombies maps? Is there any custom software I need to download for making these maps? Any help would be very appreciated

Yup, all u gotta do is download Radiant Editor or something similar, to create/edit maps, the textures are usually .dds or .iwi and the maps files are .bsp and u can edit/create using PaintNET and iwi_dds_fast_converter
Ps: sorry for my bad english
