Any tutorails on map desingning?

Don’t know if this is of topic but I want to make a map for a fps game but i can’t find any tutorials.I’m using blender but a other free 3d modeling program is good to.

If you want to know more about the tools you can use. Well, you are already using Blender that I think is the best free modelling program. However, I will mention some non-free software:

These are for building your models. If you want some software for building the levels, ProBuilder 2.0 (in the Unity Asset Store) is recommended by many: Unity Asset Store - The Best Assets for Game Making
