OFX USA Mega Mesh FSX & P3D

OFX USA Mega Mesh adds terrain mesh advertised at five-metre spacing for FSX and Prepar3D. OFX Simulation lists coverage of 9,826,675 km², including the United States, Puerto Rico and US territories in the Pacific.

Mesh changes the terrain’s shape: peaks, valleys and slopes. Five metres describes the advertised grid spacing, not a guarantee of five-metre vertical accuracy or photographic texture resolution.

The 3.16 GB download is divided into five parts. Obtain all files belonging to ofx_usa_mega_mesh.zip, extract them into the same folder, then run ofx_usa_mega_mesh.exe to install the scenery. Download time depends on your connection and plan; Jumbo options are described here.
