Creating custom map

[SirMichcik]

Hi! I am getting started with making my own CARLA Simulator map and i was wondering if anyone could help me understand how it works. So far i know that the way of doing that is using RoadRunner, which is no longer availible. So i need to use other tools. Generally the map i need is an indoor map. What is the correct way of making it work? What tools should i use to achieve it? Thanks in advance.
