I have add-on mesh installed (FSGlobal) which has entires in the Scenery "manger" section of preferences in FS2004 and so can be moved up or down in the precedence order.I was wondering what happens when I install some sections o higher resolution mesh (e.g. FSGenesis 38m mesh http://library.avsim.net/search.php?CatID=...Go=Change+View) which does not have any entires in the Scenery "manager" (installation instructions simply say to extract the BGL file to [fs2004]sceneryworldscenery but there is no mention of adding any areas within FS2004).Will FS 2004 auto-magically use whichever terrain files have higher resolution? Or should I uninstall FSGlobal product in order to be able to see an improvement from installing FSGenesis 38m mesh?Thank you,Michael

Thank you. That page clarified quite a bit. But I still have a few questions:1. I assume LOD "flag" of some sort is embed in mesh files so that FS2004 KNOWS what LOD it's dealing with and can prioritize it accordingly?2. What is the LOD of MS FS 2004 DEFAULT global mesh (assuming there is one LOD; or does it have different areas with different LOD?)3. About this scenery http://library.avsim.net/search.php?CatID=...&Go=Change+View :a. Is there another location where one can download the entire free 38.2m set in one step? Or does one have to download 71 individual files and extract them one by one?b. I understand 38.2 m is the source resolution of this set. What is the LOD? (readme.txt does not mention LOD)4. This free mesh http://www.simviation.com/fsdterrainsrtm.htm has instructions for FS202 installation that are even more convoluted than the 38.2m mesh above (this is by no meas a complaint BTW; I have got to assume that it is because hard drive space only recently exploded and tings had to be split up into much smaller chunks only a few years ago; whereas these days quite a bit of terrain data can fit on a 500GB drive). However there is no steps for installing under FS2004. (outside of the mention that it does work with FS2004).a. Can I install this mesh in the same way as the 38.2m files above? That is simply drop extracted .bgl files into [fs2004]sceneryworldscenery directory? Or do I have to go though the process of manually adding some 700 entries into the Scenery library?b. Same question as above - is there an alternate location that would allow to download the entire sent in a view less than 700+ chunks?Thanks again,Michael

>1. I assume LOD "flag" of some sort is embed in mesh files so that FS2004 KNOWS what LOD it's dealing with and can prioritize it accordingly?yes>2. What is the LOD of MS FS 2004 DEFAULT global mesh (assuming there is one LOD; or does it have different areas with different LOD?) There are multiple.Go here:http://portal.fsgenesis.net/modules.php?op...artid=10&page=1>a. Is there another location where one can download the entire free 38.2m set in one step? Or does one have to download 71 individual files and extract them one by one?You can buy the current from FSG. They are grouped into areas. I think the US has about 6 areas IIRC. They can also be had on CD. Can't speak about other vendors of large-area mesh.>b. I understand 38.2 m is the source resolution of this set. What is the LOD? (readme.txt does not mention LOD)38.2 m is the resampled resolution of the data. This is just another way of saying it is LOD10. The two are identical. The source resolution can vary. In many places there is is 30 m (aka 1" of arc) data. In other places there is 90 m (3") data. With the 90 meter data, the designer has to choose rather to over sample or undersample to achieve either LOD8 (152m) or LOD9 (76m). Much of the available source data has some problem areas that must be corrected prior to generating the mesh. Note: to actually render the 38 m mesh at full resolution, you must set:TERRAIN_MAX_VERTEX_LEVEL=20in your fs9.cfg.Note that FS9 will only completely render the highest resolution mesh in a ring around the center of the view selected. As the terrain recedes into the distance (from the POV of the view window) lower resolution mesh is used (to save memory usage to cache the mesh) and less of it is actually rendered, a more complicated process which takes into account the "hilliness" of the terrain and attempts to keep the error of the rendered terrain (compared to the LOD mesh that is cached from that distance from viewer) within a certain error limit.scott s..
