Strange scraping sound on touchdown

[Rich]

That is a duff file, this is what you should have.

No sound mentioned. ai_touchdown2.wav does not exist, make a new txt doc copy paste this into it, rename the new txt doc to


fx_tchdwn_s.fx that should give you a good file.

[delta_lima]

Thanks Rich - will try once I get back from work.

Best regards,

[delta_lima]

That worked. How bizarre, since that's a file I've never edited or touched prior this situation. How does it become "N/S" ... strange.

Thanks so very much Rich - I would never have even begun to know where to tinker!

DL

PS: Kind of related, but a bit OT ... hands up how many of you like the huge white billowy touchdown "smoke" that comes with so many stock (and sometimes addon) a/c? I find myself changing it everytime I see it. I have found the Alphasim Scimitar and F-105 have nice, subtle puffs of smoke that are far more (IMHO) realistic - and I add them in every single [effects] section. So the question is, is there a away to change that default ugly effect to one such as these? That way, if an a/c comes stock with nice effects, then FSX will enable those. But for any other, then the "new universal stock" effect will activate. Theoretically, then, you'd always have either a nice universal stock effect, or a likely nicer custom effect. Thoughts?

[Rich]

I did'nt tinker only opened my fx_tchdwn_s.fx with notepad and copy pasted it here.

You could also just copy the file from Fs2004 effects, you will never find it in the FSX install disc's but easy to find in the Fs2004 disc's.

I keep a backup of FSX everything just about.

[Rich]

DL you did'nt tinker with it

Hooray!

That worked. How bizarre, since that's a file I've never edited or touched prior this situation. How does it become "N/S" ... strange.

It was installed by some I suspect AI setup overwriting your copy, the people who do these addons are as far as I am concerned HACKERS who can mess up the sim when overwriting default effects. It could have been a replacement AI soundfile that went wrong but it should not have been using a default effect.

Someone who has no idea what they are doing will either reinstall out of hand, or try to fix and still end up doing a reinstall, a lot of work and time wasted.

I avoid auto installers and install to a dummy folder so I can see what there is.

Ranger75 is due credit he had the problem and fixed it, I never had the problem so knew nothing about it

[delta_lima]

Indeed Rich, wise words regarding the auto installers.

I don't like them, and since at least the last 4-5 years, have never once installed directly to an active FS9 or FSX install - always to a temp folder, and then manually copy over what I want. Gauges in particular, I'd rather keep with the a/c in question, and of course you can't know what's going in there if you auto-install. In this case, I must have somehow overwritten the stock file. It was dated 2006, mind you ... don't know. Anyway - glad it's cured.

Well, to you and Ranger - many thanks!

DL

[Ranger75]

Happy to hear it's all sorted out for you too D-L. Glad you brought the subject up! How and when the effects file got changed is unknown for me as well, but at least all is back to normal - until the next wacky FSX mystery surfaces!

[Rich]

Did a bit of Googling and found the source of the problem.

This turned up first = here

ftp://60.242.5.113/Flight%20Simulato...0v2/Readme.txt



The download is here on Flightsim.com =

Modified touchdown effects for AI --- Version 2

This version updates the earlier files and makes the smoke

effect much less bulky.

These files change the default FSX tyre burn smoke effects,

making them less dark, more transparent and with a bit more

vortex swirl. I've also added tyre screech, which can be heard

if within 100 metres of a landing AI aircraft (assuming it has

been set to display this effect)

Make sure to backup your original fx files just in case you

don't like these.


INSTALLATION

1. Backup the fx_tchdwn.fx and fx_tchdwn_s.fx files in the

FSX>Effects folder

2. Copy the fx_tchdwn.fx and fx_tchdwn_s.fx with this package

into the FSX>Effects folder, overwiritng the existing ones.

3. Copy the ai_touchdown and ai_touchdown2 files into your

FSX>Sound folder.

So you have the author and one download location

[delta_lima]

So I decided to install Thomas Ruth's FSX L-1011 and DC-10 for a bit of a change ... didn't touch the effects folder ... the scraping sound is now there again. Tried a couple of different soundsets, including the HJG RR set specifically for the L-1011.

Affected aircraft currently are

• Aforementioned L-1011 and DC-10,
• Maltby Trident and BAC-111
• My HJG Convair 990

In all cases, I've got the proper soundsets recommended and/or provided by the developer.

Also installed, but not affected aircraft

• Vistaliners 727 = ok
• TinMouse 737-200 = ok

These are the only additions since I reported all ok a week or so ago.

Most bizarre.

[Rich]

Check the Effects section of the affected aircraft for fx_tchdwn.fx it is another that was replaced the by the Ai effects install, that is probably the one causing it.

In the attachment zip is the three fx_tchdwn files find and replace all three in your FSX effects folder, as far as I can see fx_tchdwn_m.fx should be ok but you can change it anyway.



fx_tchdwn_s.fx as far as I can tell gives the smallest amount of smoke.

fx_tchdwn_m.fx is medium

fx_tchdwn.fx most smoke


so when you do your editing in the effects section all you are doing is changing the selection of those three.

Check your main FSX sound folder for these 2 sound files and delete them they are not default FSX sounds


ai_touchdown and ai_touchdown2 files

All the clues and answers are already in this thread !!!!!


fx_tchdwn.zip

[Paul Anderson]

This is not an answer, but a question. The answer may be the missing piece of the puzzle.
Aircraft.cfg SDK: 14th contact point parameter is the sound type.

14 (0)	Sound Type	This integer value will map a point to a type of sound:
		0 = Center Gear,
		1 = Auxiliary Gear,
		2 = Left Gear,
		3 = Right Gear,
		4 = Fuselage Scrape,
		5 = Left Wing Scrape,
		6 = Right Wing Scrape,
		7 = Aux1 Scrape,
		8 = Aux2 Scrape,
		9 = Tail Scrape.

So the question(s):
Which sound files or effects are represented by these types?
Does an entry in the sound.cfg (left/right wing scrape, fuselage scrape) override the mystery default sound with the sound file specified in that section?
(so many things in the sdk assume too much knowledge on the part of the reader, would think developers would have cracked this - any out there reading this thread?)

[Rich]

Paul there are very few aircraft contact points these days have entries in the sound bit as per SDK it is a left over from CFS2 Fs 98.

Aircraft.cfg effects section is visual effects except in this case the default visual effects have been modified to include sound this is what is causing the problem, the default fx_tchdwn effects of which there are three and have no sound have been replaced by ones that have sound, this unfortunately will appear on every aircraft that calls for that effect in the effects section in aircraft.cfg hence big airliners and small aircraft like the Vampire that was mentioned will all be affected.


Default effects =

[EFFECTS]
wake=fx_wake
wetenginewash=fx_spray
water=fx_spray
dirt=fx_tchdrt
touchdown = fx_tchdwn_s.fx, 1 = min smoke effect with no sound
windshield_rain_effect_available = 1

[EFFECTS]
wake=fx_wake
wetenginewash=fx_spray
water=fx_spray
dirt=fx_tchdrt
touchdown = fx_tchdwn_m.fx, 1 = med smoke effect with no sound
windshield_rain_effect_available = 1

[EFFECTS]
wake=fx_wake
wetenginewash=fx_spray
water=fx_spray
dirt=fx_tchdrt
touchdown = fx_tchdwn.fx, 1 = large smoke effect with no sound
windshield_rain_effect_available = 1

The modified effects in the effects folder will give unwanted sound !!, going back to the default effects will fix this as previously shown a week ago it was fixed now it is back this time I suspect for the same reason but with fx_tchdwn.fx being called for the other modified file mentioned in the download to modify these effects.

I may well be wrong so will leave this subject alone it's gone on long enough.

[delta_lima]

Hello Rich,

I subbed out the 3 effects with the ones in the zip. The sounds in question were not present in the FSX/Sound folder - but regardless - the issue seems to be sorted now.

Many kind regards!
