New Map

Do you have UltimaLive installed?

 

Someone may correct me if I am wrong. Without modifications the client won't support additional maps. That isn't to say you can't replace an existing map with a new one. You can create multiple "copies" of the map. So registering a map of 32, but referencing a map 0 for example would work.

Once you have the map installed and configured the server all you have to do is use the "set map 32" command.

 

If you are trying to keep your Tram or Fel maps, this may not work without UltimaLive. If you don't care about either the tram or fel map. You will need to change your Map32 files to replace either Map0 or Map1.

Once that is done you will need to update:
RegisterMap (32, 6, 6, 6144, 4096, 3, "Two Welten", MapRules.TrammelRules);
to:
RegisterMap (32, 0, 0, 6144, 4096, 3, "Two Welten", MapRules.TrammelRules); //Uses Map 0 Fel Map files
or:
RegisterMap (32, 1, 1, 6144, 4096, 3, "Two Welten", MapRules.TrammelRules); //Uses Map 1 Tram Map files

 

I don't believe you can have have a map32 that will use a separate map32 fileset, because the client wont be expecting it.

You can have a map32 that either replaces or reuses one of the built in map's files, but AFAIK you are limited to the number of maps the client can see. So if you, say base your map32 off of trammel, then the map and frozen statics will be the same for both trammel and map32. The items/mobiles can be different, and they will be treated as separate facets, but the terrain and buildings will be the same for both.

I also haven't played with any of this in a long time, so I could be wrong.

 

Damn, they are up to 6 maps already? I've been out of this game for far too long.

But yes, out of the box, that appears to be the case.

Taryn mentioned UltimeLive, I believe this may be what is being referred to: https://www.servuo.com/threads/ultimalive.4968/ and it appears to do what you are seeking, but I myself do not have any further experience or knowledge of it, having just searched it when it was mentioned.
