[BHaType]

Descriptions:
Allows you to create buildings on the map and save them.
Allows you to create your own configs and add them to the model only those that you need

Note:
I know that there is a stripper but as for me it is too long and difficult to create objects on each map through the stripper.
I know that there are other Spawner but they have their problems.
Did not test this plugin in l4d1

Some guide how to create your own configs:
In the data/builder folder you create your config with the prefix .ini then the name of this config you need to add in config build_custom then simply add the models you need in your config.

!b - Opens the menu.
