Create landscape with high altitude

Hello!

I’m tring to build a larger terrain with big moutain, i have put Z scale at 200, and for make highter moutain, i’m consider my Z0 about Z-250

Currently, i use the sculpt tool for raise the terrain mannualy (up to Z-255), but it’s very tedious!!!

Someone have a tip for creation the terrain directly at, for example, Z-250?

Thanks for your help, and sorry for my bad english :slight_smile:
