How do some strategy games have a terrain that blends with a changeable map? I mean what is the technique that developers use?

For example,

  • Can you explain your question better? not sure about what are you looking for – joreldraw Nov 17 '17 at 09:19
  • Yes of course! i'm looking for the recommended way to make the terrain like this without turning it into a mesh and assigning the texture on it, I only looking for an explanation is it a coding thing? or shaders..etc – vaolez Nov 17 '17 at 10:55
  • but your terrain is a terrain? you change land randomly in runtime? only need to match the texture? what are you trying to do with this zones? – joreldraw Nov 17 '17 at 11:00
  • Ok there is no problem to convert my terrain into a mesh because i don't want to edit it in runtime, the main question is about what is the way to make the changeable political map to match the terrain mesh – vaolez Nov 17 '17 at 13:52

I suspect that they actually splice the terrain into different meshes for each of the provinces and then assign a different material and texture to it when it changes hands.

Finally I found a good way to make this work

Unity has a feature or component called (Projector) you can use it to make your texture blend with anything meshes, terrains, and you can place a shader to the projector if you want to change the territory color in runtime! I think this is one of the tricks that strategy game developers used
