Hi, I am wondering whether I have this right in my FS9 scenery file. I have many mesh addons, and also many addon airports. In which order do I need to put them? Right now I have:1. Airport sceneries (e.g. Aerosoft, Flytampa, etc.)2. Mesh sceneries3. "Addon Sceneries" (= the "scenery" folder in Addon Sceneries that has all the AFCADs)4. Default Cities5. Default areas of the worldIs this correct? I am just asking because when I ninstalled one add-on I was told that mesh files should be above (higher priority) than sceneries, and sceneries should be above Landclass files.Thanks for any clarification

Hi, I am wondering whether I have this right in my FS9 scenery file.

Is this what it looks like in the Scenery Library?I would move the mesh to the very top, for more info read this - http://forums1.avsim.net/index.php?showtop...t&p=1609329Hope this helps,Joe

I guess it all depends on the author of the mesh. Becuse if you seen the instructions for FS Genesis mesh it says to put those file in the scenery\world\scenery folder. But I have seen other mesh files where it says to put the mesh files on top of the airport scenery files.

Hi, scenery fans. I think the logic of it is: The mesh is the 3D look of the terrain/ground.The the landclass is the general-type of the look. City? village? desert? forest? etc. . .The landclass is like 3D-painted ON the mesh.And finaly, the scenery goes "over" that. it is deposited ON the mesh and landclass. So FLight Sim HAVE to read :1- The mesh(es),2- the landclass(es),3- the sceneries. . . . . .right ?Blue skies.

This is from a post on another forum by Holger Sandmann concerning priority. Hope it helps.

Hi guys,lot's of confusion here, indeed GrinSo here's the scoop:FS knows several different categories of landscape elements: terrain mesh, ground textures (landclass plus autogen), vector and polygon data (streams, roads, water bodies, etc.), airfield data (AFCAD) and custom objects (building models).The important thing to remember is that FS loads files by category meaning scenery library position is relevant only within a category not between categories.In other words, it does not matter whether mesh file entries are above or below land class file entries, or water files below AFCADs etc. FS will sort it out just fine.So why the often mixed message about priorities in the scenery library?First, there is the issue of priority of terrain mesh files. FS will automatically display the local mesh file with the highest level of detail (LOD), regardless of where its entry is in the scenery library. The only time scenery library priority comes into play is if there are overlapping mesh files of the same LOD. In FS2002 and FSX, the rule for this case is handled logically: the mesh of the same LOD but with higher display priority in the scenery library menu (i.e., above the other mesh entry) will be used. For some strange reason, in FS9 this rule is reversed; it's the mesh file lower down in the menu that will be displayed.Since FSGenesis, FSGlobal, etc. are considered base mesh files, and other scenery add-ons may include their own mesh file of the same LOD, the suggestion for FS9 users is to place the library entries of FSGenesis etc. at the top of the scenery library menu. That way the local mesh files will be used in their own coverage area. Again, it's the opposite if you're using FS2002 or FSX!For example, our FS9 Vancouver+ product includes custom 38-m terrain mesh files. The Canadian parts of FSGenesis' 38-m Cordillera files are similar but not identical (different processing). The difference isn't major but you'd notice it at bridge ramps, helipads, etc. If the Vancouver+ scenery library entries were placed above the FSGenesis entries it's the FSGenesis mesh that would be displayed, which is undesirable.In short, if you have installed add-ons with terrain mesh of the same LOD then you need to consider scenery library position. If you don't then it doesn't matter where your mesh file entries are relative to one another or other entries.The other issue is that complex add-ons like VOZ or Misty/Tongass Fjords require a specific order of their multiple scenery library entries so that local excludes work correctly. That's the only other case in which order of scenery library entries is important. The add-on's manual should give the required order of entries.Actually, there's one more case: if you have different airport facility (AFCAD) files of the same airfield in separate scenery library entries then it's the one with the highest priority that will be used. That's why many people suggest that all AFCAD files be placed in a single add-on folder (usually \Addon Scenery\scenery) so that duplicates are easier to spot. Alternatively, tools that detect duplicates can be used to prevent issues with AFCAD files.Of course, there is something to be said for keeping a scenery library with many add-on entries in some kind of order. For example, I sort my library by region/continent so that I can spot more easily whether there may be potential overlaps or conflicts between specific entries.Hope that helps.Cheers, Holger

Thanks folks, that was very helpful.CheersChris

Chris, the whole idea of being able to adjust the look of the simulation is just that...having the ability to adjust it. I don't believe that there is a silver bullet here and it's in your best interest to look at the sim from the perspective of what is working for you and what is not. Be certain that there are layerings that need to take place, although, each individual scenery should take care of that or let you know it's particular requirement. In other words, if the elevation mesh developers require that their software to be at a specific scenery layer, then by all means try it where they suggested. But if it's not mentioned or required by them, then put the elevation mesh where ever you want to and take a flight. See how it looks and how the other scenery around it looks. If you don't like the way it looks then try changing where the elevation mesh is layered, or the other scenery, or both. The important idea here is that you decide which one looks better in your sim.It doesn't matter if you're experiencing CTDs, crummy frame rates, or a perfect simulation. You're going to be doing this anyway...no matter what...for ever. That is at least as long as your using FS9. So you might as well start with that mind set because we're all on that pathway. The difference is that after adjusting stuff for awhile, you get used to being prepared to re-adjust stuff :)I'm setup like this...and like it for now...but that could change!1 Airports2 Landclass3 Elevation Mesh4 Static Object Libraries5 Global Afcad6 FS9 Default ObjectsMark
