Connections with maps

So i have made different maps (towns, routes, etc). And i made connections between them and all but when i connect a town map to a route map i do the transfer like it should but when i test it in game it fades out and does the door opening sound instead of just going to the next map.

My question is: Is there a way to make that transfer between a town map and a route map seem invisible like in the actual pokemon games or does it all have to be one big map?

Visual Editor in ''Editor.exe''

Have you tried that yet?

Thanks! That helped a lot!
