Source engine map sizes


I am looking at trying to create my own maps using Hammer, what is the maximum map size for a source engine map?

How would I make different areas link together without a physical connection much like in rp_evocity_v5p?

Thanks guys.

The max map size is 16384 * 2. You can teleport with an areaportal and teleporter.

Thanks code_gs. When you say 16384 * 2, I don’t quite understand how that describes the max map size because surely no map is going to be only 2 hammer units in one direction?

It is around 32000^3. It is big as the hammer grid goes minus a small margin.

It’s actually 32768^3 but you’d have to keep your map like 64 or 128 units away from the grid bounds so it compiles without warnings.
