Thanks for your interest guys ! ;)
This is the "hard" trick to do as far as the "edm model" of the FARP is rectangular (elevation in mountain) and we all (or almost) have different TERRAIN MOD, I'm using Tobey's "Low N' Slow" but the render could be very different with "DTAC Terrain textures" for exemple. Tobey's mod also required a NOISE modification, I can see how to merge terrain and Farp texture with this method.
Will try but no garanty ;)
This is a good idea ! I will ask Hungarojets to get permission when I'm satisfied with my textures (4 seasons to rework, my screens shows actually "Spring" )
