FS X terrain fix

Recommended Posts

FS X terrain is defined in the terrain.cfg file that can be found in the FS X root directory.While testing FS X, Dick Ludowise (rhumbaflappy) and I made various modifications to the file.For most users, the principal modification concerns the display of water.Responding to complaints from users, the FS X team eliminated the sloping water that displayed in previous versions - now, when water encounters a slope, a rock texture is displayed.Unfortunately, this has an unwelcome side benefit in that many rivers now display rocky patches in them, for example, the Thames in London:http://forums.avsim.net/user_files/160725.jpgWe have modified the terrain.cfg file so as to eliminate these patches of rock in all the water bodies throughout the world:http://forums.avsim.net/user_files/160726.jpgIn addition, our modified terrain.cfg file will provide many benefits for FS X scenery and scenery designers.Please download the file from the Avsim library and install it. It can be gotten here:http://library.avsim.net/esearch.php?DLID=...rado&CatID=rootBest regards.Luis

Will this change have an effect on anything else in the game unintended or will it just fix this problem? Thanks for your hard work!Dave

Thanks for your>hard work!>>DaveHi Dave.The alternate terrain.cfg doesn't affect anything unintendedly. We did it on purpose! It fixes a few problems, and adds some functionality for new scenery design. We encourage all terrain designers to include this new terrain.cfg zip file with their packages, along with simple instructions to use it.Dick ( Richard Ludowise )

Hello,When I use this fix and "fly" with multiple monitors configuration I have a big stutter (the game freezes 1 during second) every 7 seconds as soon as I undock any windows (2d cockpit, radio, GPS, ...) to an other monitor.Any recommendation?Thanks in advance.

Thanks so much for this Luis, Dick... :) It's a big improvement, even though there are now a few rather odd looking depressions in the water affected; not your fault or problem, of course! I'd never noticed this before in FS9; I wonder how it got through testing in FSX when the decisions were made - surely some mesh modifications could have levelled out the offending parts of areas such as on the Thames...?!? Anyway, your new config has fixed a much more unsightly 'error' in several major British rivers that I've seen so far; again, many thanks :)

FSX has far more sloping water than was present in FS9. 2) Rivers are NOT draped on the terrain. FSX water does not "encounter a slope" - it IS sloped and it does have an effect on the terrain (sometimes undesirable). The water polygons are carved up into smaller pieces which are explicitly placed (by software) in 3 dimensions. 3) The game (as shipped) chooses the rock texture for water polygons that are "steeply" sloped. The fix being discussed in this thread merely chooses a water texture for the steep polys. If you look closely, you'll probably see water doing unnatural things - it's just harder to see from the air at a distance.The mechanism by which the sloping water works has been completely replaced. The fact that there is room for improvement is very apparent to us. Software for bulk processing of GIS data for the whole planet is a very difficult beast - correcting a problem in one location carries the very real risk of (badly) messing something up elsewhere. The drastic increase in complexity and vertex density of the vector data in many places in FSX presents far more opportunity for bad things to happen, and makes it far harder to fix things when they do. There was, unfortunately, a limit as to what could be accomplished prior to ship. This topic (quality of sloped water / missing rivers) is present on the "roster of issues" Phil Taylor mentioned in the "Path 1" section of his now-famous post (http://www.fs2004.com/forums/index.php?showtopic=95173).The current atmosphere on AVSIM (:-newburn) made me really think about whether I wanted to post or not. In the interest of getting some real information out I decided to take a chance. Please don't make me regret that choice.-Doug @ ACES

Absolutely, Doug. Many thanks for your corrections and the more precise details.In the interest of simplification, I did not mention all of that, since most people would probably not understand the technical aspects, and were just looking for a simple fix.But, I must categorically state that the work done by the FS Terrain Team is outstanding and of exceptionally high quality. It is inevitable that some small parts of the world will not display optimally, and this does not in any way diminish their accomplishment.Best regards.Luis

Doug - I think the majority of the regular posters here at Avsim are appreciative of the first hand info being delivered by the Aces Team. there are a few that might bite a little :) but we're generally a good bunch. I may be too easily satisfied or maybe it's because I was a programmer for many years, that I don't get largely upset when I see an anomaly like the bridges in FS9 or the rocky water in FSX. Other than the fact that the product I just purchased is not *perfect*, it really doesn't affect my flying enjoyment. And that is the bottom line to me - do I enjoy the product - is it perfect> Nope but neither am I so we're even.Currently I'm just having a ball exploring FSX and that's a good thing.Tell anyone at the Aces Team that they're welcome and flame retardant clothing is optional.Vic BaronVisit the Virtual Pilot's Centerwww.flightadventures.comhttp://www.hifisim.com/Active Sky V6 Proud SupporterRadar Contact Supporter: http://www.jdtllc.com/

Thanks Luis & Richard, great job..:)You fixed up my "sandbars" by CYVR, I'm running the UT port and all looks good.Glad you stopped by to participate Doug. I doubt anyone here is going to blast "helpful" information from the team ! Were just a passionate bunch, and obviously you are too for taking the time to post. Regards'Garett

Thanks Doug it has been very hostile in here. I for one think ACES has been very forth coming in keeping us up to date. Its just a few posters who seem they must bash ACES or FSX in every thread that has made the whole FSX forum look bad. Hope you still keep us posted in the future.:-)

> Tell anyone at the Aces Team that they're welcome and flame retardant clothing is optional.I would say flame retardant clothing is mandatory! I certainly appreciate the visibility of the Aces guys though, at least we know they are listening and as shown are helping where they can.Some customers feel that they should be treated as god while being allowed to treat the vendor as crap but I think most of us remain fairly civil. :-) We have even less reason to complain this time around because we had a demo to play with before purchase! I had to remind myself of that because I to was upset with the performance on my new system even with sliders at minimum. Speaking of performance: FIBER_FRAME_TIME_FRACTION between 0.00 works wonderfly on my machine.

G'day,> thx (cool name BTW)Thanks :-)>Therefore, I assume FIBER_FRAME_TIME_FRACTION 0.00 is in effect not doing anything, or refreshing once per cycle in the default manner.I had wondered the same thing. Unless we take care to load the exact same scenerio and only make one change at a time it can make framerate testing difficult. Especially if the level of clouds changes between tests. On the ground at YSSY it doesn't make much of a difference but at 500 feet it certainly seems to.I have been playing with the value more because it was taking a long time for the hires textures to load (10 seconds when paused!), I have found that if I set it to 0.07 and have my framerate locked such that it is 4-5 FPS lower than if it was set to infinite the 1m textures are loading fast enough to fly around at ~140kts. That seems to be what is happening anyhow! At the very least I can see a difference in texture loading time.

Thanks for the info!As to the current atmosphere to me it really seems that there is a very small irrational and vocal minority in these forums that take every opportunity to take a dig at Microsoft and Aces.I'm one of many who are extremely happy with the new sim!James
