Hi all This must be such a common problem, I feel!!!I have several ground polygons in the scenery I have designed, and it seems that those where I used the 'Texpoly' command don't suffer from the strange behavior.Using the 'Loadbitmap' and 'points' command, when I get low and close to the polygon, it starts moving forward revealing the seed tile underneath, or somestyimes, non-existant, but fine from altitude.I wonder whether this is to do with either, v1 & v2 settings, or even the 'Flatten' command (altitude setting).Hope someone can point me in the right direction.any help appreiciatedRegards Dave

I suspect not a lot of research has gone into this, cuz its now easy to replace the textures directly on the mesh. This is done using terrabuilder or manually using the sdk tools.Bob B

I had that problem as I drove around my airport and the taxiways would just disappear. Using my joystick hat switch, I rotated around my aircraft and the scenery would come and go. It was worse the further away from the Reference Point. I found increasing the V2 fixed the problem.

Hi guysthanks for the replysI'll check the v2 settingsThe strange thing was I was about to release my freeware scenery and in doing so, was in the process of creating a excutable file for the installation of my scenery, when testing the installation came upon this problem.How about when you haven't assigned a v2 setting?thanks for the supportRegards Dave

Hello!This is known problem, especially with FS2000 scenery imported in FS2k2.:-roll The answer lies in layering. If You make ground using API, so You have many textures in macro You MUST use LayerCall instruction and put this ground scenery on Layer 8 otherwise You can see mesh even if You put flatten switch in Your scenery properly. And since I read, this is not Your scenery, then You should contact the author of it and request an update :-(. Hope this will help You.Regards,Goran BrumenFS Slovenija 2002 teamhttp://slovenia.avsim.net

This should indeed be the problem. Most of the time people use the code for 3D objects (with the PerspectiveCall) also for ground polygons and FS can not handle that. So always use the LayerCall for ground polygons.Arno

hi all Thanks for the repliesThis is my own scenery design, I am the author heres the code in question; -------------------------------------------------------------------; Polygon: Inner Grass Area( 5 52:38:3.771774 -03:09:15.051737 5 ) IfVarRange( : 346 2 4 ) LayerCall( :layer 8 ) Jump( : ):layer RefPoint( rel :TagPoly 0.304800 52:38:3.771774 -03:09:15.051737 v1= 2500 v2= 1000 ) LoadBitmap( 0 0 0 0 0 0 grass.bmp ) Points( 0 -4 0 -14 271 0 351 428 0 237 142 0 -141 ) ConcavePoly VecPoly( au 0 1 2 3 ) :TagPoly:NoRamp Return EndA I have recently installed Largo Terramesh (England & Wales), when I removed this from FS2002 it solved my problem, bar one polygon which I still can't resolve. thats the code aboveThis is the code for the Flattening thats at the head of my bglFlatten( 70.018097 4 52:38:14.593119 -03:09:20.528045 52:38:4.131959 -03:09:0.196395 52:37:32.341526 -03:09:28.538377 52:37:43.616949 -03:09:55.334438 )Tried to upload picture and couldn'tMight this problem be 'Bleedthrough' to do with Z bufferingStill stuckthanks Dave

Hello Dave,The problem you describe is probably due to an improper (or insuficient) Flatten. Be sure that the runway (which has its own internal flatten action) and your flatten polygon have the same altitude. Be sure that the flatten polygon extends further than all your flat ramp, taxiway, etc polygons.What follows has nothing to do with your problem but:1) there is an error on your Flatten sintax (excess of arguments). It should be:Area16NFlatten( 7052:38:14.593119 -03:09:20.52804552:38:4.131959 -03:09:0.19639552:37:32.341526 -03:09:28.53837752:37:43.616949 -03:09:55.334438)End16Be sure that the poly is convex and the vertices are in the right order (don

Hi Guysthanks for the cluesI hope I have resolved my problem and as Luis suggested, I think the problem was a flattening issue.It was a combination of moving the area of the flattening polygon and changing the flattening method from the bgl to the scenery config file. (A Flattening switch, I think)My concern is that this problem did not exist with the Visual Flight mesh, only when I changed to the Lago terramesh did this problem occur.Will my scenery view correctly when installed on another persons system, that is my only worry now???Thanks again for the supportRegardsDave
