Hi All,I'm new to mesh design and would like to know the optimum size of a mesh BGL from a performance stand point. By size I mean number of (1 degree)Lat Long tiles per BGL. I'm using 3arcsec SRTM data for the sub-continent of India. N14 to N16 and E73 to E82 gives me a BGL around 30 megs in size. Is this ok or should I split it down further.Thanks in advance,Keith

Hi Keith,I've routinely compiled terrain BGLs much larger than that. BGL size really doesn't matter, as the terrain engine will only load those pixels within the hard-coded range of the prevailing LOD anyway.-------Justinhttp://www.fsgenesis.netHigh Quality Scenery for FS200x

Thanks for the response.Keith
