yes you are right... The maximum would be something like 3 layers and then its gone!
What is causing the Max_Patches error? Not enough RAM?
As i sai to Matze the teleporter thing would work better in specific areas for example in a castle and you got a garden inside it, so just put that into an extralayer...
Another question @ you, Jitspoe or those who know it... What does the trigger do at the end of the tutorial? is it just a trigger that activates local a command? If so, it would be too easy to do... (EeeeZ XD)
You could make several parts of the map, connect those by triggers that connect you to other server with the other map inside and let those people travel between cities and towns for example!
Would be cool too and helpful for RPG too!
We'll see!
