If your SimFlyer airports are showing terrain bleedthrough or possibly other problems, try editing the Terrain section of your fs9.cfg file as follows:Edit "TERRAIN_MAX_VERTEX_LEVEL=19" to "TERRAIN_MAX_VERTEX_LEVEL=21"This cleared up multiple locations for me. Forgot to do this after rebuilding my fs9.cfg file and had all kinds of bleedthrough.Unfortunately, this did nothing for EDDF or CYYZ. If anybody knows a solution for these it would be greatly appreciated. Terrain follows the aircraft movement down the runways errasing the hard surface.Everything else looks fine (i.e. aprons, taxiways, terminals etc.)Happy flying:RTH

I don't get terrain bleedthrough but I do get flickering/disappearing taxi lines and other markings - I'd love to know what'll fix those, 'cos nothing I've tried so far has.Ian

RTH, I have experienced that in the past, but during my treks through the forums to look for answers, I found this and it seems to work. Open your scenery.cfg file and scroll to the CYYZ area as shown in my file below. See where it shows "Flatten.0"=568, that is the elevation for the airport. Now I think it read 567 before, causing this ground texture bleed through. I simply changed it to 568 and everything is OK now. As a note before the fix, my bleed thorugh only occureds on the runway tarmac, everything is fine on the taxiways and aprons. Anyway give this a try, I think it should solve your problem as it did mine: [Area.059]Title=Toronto Pearson (CYYZ) by SimFlyersLocal=SimFlyersCYYZRemote=Required=FALSEActive=TRUELayer=64Flatten.0=568,N43 41.98,W79 38.40,N43 40.92,W79 35.17,N43 39.48,W79 37.36,N43 40.42,W79 40.44Regards,Tom

Sometimes if you move those up in your library file it fixes the problem. Kind of a weird fix but it works.

Well, so much for that idea. The "21" edit did not last very long. All of my original problems with flashing and bleedthrough are back (See KPHL Post on the SimFlyer forum). Thanks for the ideas folks. I will try your suggestions.Sorry!RTH

Tom: Sorry, but the flatten edit has already been made as you suggested.Jeff: Sorry, but some of the problem locations are already at the top. I will remove and reactivate all of them there and see what happens.Thanks guys:RTH

For what it might be worth to anybody, I deleted all SimFlyer files and reinstalled them (for the third time), and all problems went away.I have no idea why it didn't work on the other tries, or how long it will work presently.Happy flying:RTH
