I'm new but not really... been hovering around gta5-mods for some time now, always been within the modding scene but never really published anything worth while... but soon I shall. Why? Codewalker... it's an amazing tool!
@meimeiriver and @Dekurwinator Thank you for the feedback, this has answered my question and due to my current limitations for having software, it will not be 100% possible for me. But thank you!
I shall return to this awesome tool, and focus on the maps and scenarios I am creating without the need to remove buildings for now 
Cheers all.
Hey all,
So I have recently been highly engaged with modding in GTA V and I've been looking extensively into Codewalker.
Now something I would really like to discover, and I do apologise if this has already been canswered. Can you remove entire buildings and replace them. But, also have this replicated within the game?
For example:
Removing the motel in Sandy Shores and replacing it with a newly polished bowling alley? (just an example)
I've been messing around with the flow of traffic. In fact, re-routing roads etc for map mods. But I feel like such a tool should be used more frequently for modding, as there are a lot of possibilities.
Thanks and hope my question is understood. 
Teaser Update:
Updated Signs for Metro Stations - Walls also getting paint job
Merseyside Police emblem and a new splash of paint for LSPD Police Station
Putting up some new boards around the station too of course
@Christian6984 Awesome man! I'll be releasing the first version soon. As soon as the MerPol and MerRail editing is complete. Shouldn't be too long!
Added:
Merseyrail Logos/ Adverts/Station Colours/Station Names
Merseytravel Logos/Bus Stops/Advertisements
Flags retextured for borough flags. I.e. County of Merseyside Flag.
Google Image Example of Flag:
Version One Release Date: Wednesday 30th May 2018
I have decided that version one of the retexture should be available as an initial release, it will be in no way complete, but some form of progression would be made, and you will all be able to experience a slight touch of Merseyside whilst I continue to develop the mod further.
If you have any questions, suggestions or anything else. Please do not hesitate to contact me!
The Bus Stop Design is fictional in a sense, but we have a lot of Banksy art in the Wirral area.
I have discontinued the project due to a number of factors, but primarily this is due to moving into a new career and therefore not having the time to dedicate to the project.
Apologies to all that were looking forward and interested!
Work in Progress: County of Merseyside, UK
Greetings one and all,
My name is TheBritishRaccoon, and I bring to you a new design in British related modding.
I have often noticed that apart from emergency vehicle modifications, most counties, districts and such are not really developed other than the London Borough areas including The Met.
So my goal is to retexture San Andreas into the County of Merseyside initially, then to make alternatives with other cities, such as Manchester, Birmingham, Edinburgh and so on. Why Merseyside, first?
Merseyside is my home county, well I live in this little sticky out bit between Wales and Liverpool, but not really a big concern. But, the idea is that starting with my home county will be easier in relation to knowing local businesses, councils, cultures, and the likes. And for those football fans... you may see a few flags from Merseyside teams.
So what will be included?
Merseyside Police - Retextures of all LE related things, within reason.
Local Council Boroughs - Flags/ Banners/ Billboards/ Waste Disposal etc.
Local Businesses - Restaurants/ Shops etc.
Parks - Birkenhead Park/ Sefton Park etc.
Vanilla Vehicles - Emergency Vehicles will get some nice local reskins/ business vehicles will also.
Much more to be announced over time.
I know a few people will question why I am doing something that other already do, and it's simple, most stick with London. And there is more to the UK than London.
If you find the project interesting or Merseyside is also your home town, then feel free to drop me suggestions and the like.
