Not wanting to make humongous meshes, I have decided to split a Rocky Mountain Project up into individual states (Co and Wy in this instance). However, I have found when I create meshes seperately I get gaps between them as compared to no gaps when I compile the thing as a single bigger mesh using the same hgt files. Attached are some TMFViewer shots that show my problem. An explanation of why this happens and how to fix it would be greatly appreciated.Paul Scott BarteltSingle mesh.http://home.wi.rr.com/pbartelt/combined.JPG2 seperate meshes with same data, note the gap between states.http://home.wi.rr.com/pbartelt/seperate.JPG

Hi Paul,the answer can be found on Steve Greenwood's website for mesh development and use: http://www.fs-traveler.com/tips-d.shtmlIt's obviously completely up to you what area you make mesh for and with what source data but, from a user's standpoint, making SRTM mesh of the US is completely unnecessary. For one, there's freeware meshes based on SRTM data avilable already (Rob Gainer's files have disappeared from here but there's a complete set by Stephen Rothlisberger, available at simviation). More importantly, SRTM data are inferior in quality to the USGS 30-m NED data and those NED data have been made into freeware mesh files for the entire western US by both Justin Tyme (FSGenesis) and Raimondo Taburet (FSFreeware). That's as good as it gets for FS9.Cheers, Holger

Hi Paul,good point!Making mesh files may not be very difficult but there are some "nice options" for screwing up too ;-) Case in point are those nice blue sections in your screenshot above; you certainly don't want to have those in your final product. For patching up or filling in I highly recommend John Child's Blackart utility but you've probably already read this "mantra" of mine in other posts.Good luck with you project!Cheers, Holger
