Firstly, let me apologise if this isnt the right place to ask this question. I really wasn't sure. Feel free to move it.
I'm new to RW but loving it, especially the creative part of it as building has always been my thing, In other games I've always made my own textures to suit my needs.
I've done some research and have a very basic understanding of how I could potentially replace some existing textures with my own but havent actually tried it yet as GIMP doesnt support the right format - need to get a plug in apparently.
I have also dabbled a bit with blueprints and that's worked quite well. My query is connected to both blueprints and textures. I can understand how, in a single player game, a blueprint downloaded from here can be added to my game and it appears (although I can be told Im wrong) that any textures used by the creator are included and so show up in MY SP game. My confusion lies with the blueprints that are used on the server I play on. I had imagined that there would be no point in replacing textures when on a server as I assumed no-one else would see them. However, the blueprints I have seen on the server seem to have some custom textures - I cannot understand (a) how that works and (b) how I can do it!
Im not very technical so, if you are kind enough to explain it to me, please do so in simple terms
