How to copy a detail from another terrain?

Sorry for my bad English.

I tried to copy a terrain detail from another terrain that I already created a grass, tree, or a texture. Now I try to re-scaling these terrain but the problem is all of the detail has been change too.

- I just want a template from my old terrain, I mean tree, grass, texture that ready to use for a new terrain, I don't need to create all of the thing again(with different scaling).



Example, I copy detail from 100*100 terrain to 1000*1000 terrain and I found that all of the texture size has been change 10 time bigger but I don't want it to change.

 

You can change the texture tiling in the paint tool section.

I think the two terrains are kind of in one group.
