Thank you for fast reply.

I am trying to merge two terrain patches from GE.

I am not sure about the inner workings of the script, maybe its not designed for the task I need to accomplish? Maybe there's other method for doing this?
When I execute it it seems to be working but the pop up window never shows up...and than it quits without confirmation....it does work on a single terrain patch thou

I need to make a large terrain from a number of patches with clean topology and preferably the UVs and textures to be used in an art project that is a simulation of a part of a city....Plllllease help shed some light ☀

cheers
