1-Create your base map in pyspades map editor, Terravox (vxl) or
with [Create a Heightmap Tutorial]
(https://gamebanana.com/tuts/14708)

PySpades Map Editor
https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/pyspades/pyspades-map_editor-800bb6ea1824.zip

Terravox needs Visual C++ 2013 64bits
https://github.com/yvt/terravox


2-In Goxel, Slab6, VoxelShop or use a voxelizer [How to Voxelize Tutorial]
(https://gamebanana.com/tuts/14870)  you create all kinds of models exported in .kvx

3-You open your map (vxl) with voxed to place your .kvx models with the U then save the result with Alt + F3 the controls can be annoying I recommend you change them

Change voxed and slab6 controls Tutorial
https://aloha.pk/t/change-voxed-and-slab6-controls/19681

Voxed Controls
https://aloha.pk/t/map-making-tutorial/13024

Can use this Base Map https://aloha.pk/t/9-baseplate-maps/19610
and this 450 models https://aloha.pk/t/pack-of-450-models-kvx-openspades/19578

(to save parts of the map in slab6 kv6 [max 256x256x256 voxels] you must select with the spacebar the area you want to save then duplicate it with D or T if you changed the voxed controls then move it to the air with the numpad [4,Intro,5,1,2,3 or  ←,→,↑,↓, Backspace, L Ctrl, L Alt if you changed the voxed controls] and press F7 on the object to save)

4-You create a .txt file with the name of your map inside the maps folder to be able to configure which game mode you want it to be in (it is not necessary to put scripts to play in ctf but if you want to configure it create a .txt file)
(To test your map you will need to create a server [Create a Server OpenSpades Tutorial]
(https://gamebanana.com/tuts/14441)
