Just to start I have been doing a lot of research on this and have found tools such as World Machine, World Creator, Geoglpyh, Houdini, Vue and more. Cost isnt an issue, im more looking at what direction to take and what program to target my learning on.
I tried out World Machine and found it really unpleasant on the UI/friendliness side, It didnt seem very natural to create natural looking terrain, or atleast I struggled to find a tutorial where the results were something like I would like, a lot of them looked very unnatural.
One thing that has stumped me mainly is the tiling. So from what I understand from using Unreal Engine 4’s World Streaming, I can create a maximum of 8000m x 8000m in one tile, which I can then duplicate to make a 16x8km map, 16x16km map etc. In world Machine, tiling really confused me, obviously you get a preview of a tile but I couldnt find any tutorial explaining how to make say a 16x16km map then split it up into multiple tiles.
From what I understand World CREATOR does this by default when exporting but you view the entire map in one instance?
What im looking to do really is create a 16x16km terrain and just get myself a base, where I have some mountains, hills, flatlands, lakes rivers etc and have them all cut into the terrain so I can work on them inside unreal. Any tools that will aid in creating realistic materials onto it, or trees or anything of the sort to help compliment the terrain built is obviously a really nice plus, but I think I could learn a lot from a fellow map maker here to really understand where to just start.
Thanks for any advice!
