effect linked to speed

[Bliksimpie]

Is it possible to have an effect linked to speed. E.g.
Dust effect.
At slow speed little dust, at fater rate a bit more dust, at fast rate an even more dust

here I am talking about the dirt effect file. fx_tchdrt.fx

Curently it does not matter if you go 10knots ot 50knots, the dust seem to be the same

Appreciate any help.

The short answer is certainly, yes, but there are probably a few ways you could do it.

One way of doing it would be to make a few copies of your fx_tchdrt.fx file. Then edit each of the copies in turn, to make the dust effect increasingly pronounced, so you end up with two or three files with the dust effect getting stronger in each.

Then you could use the [smokesystem] section in the aircraft.cfg file and create, say, a smoke.1 to smoke.3 and attach each one of your different fx_tchdrt files to these. Two or three smoke entries would do one wheel/contact point. You'll need to create smoke entries with the coordinates for each of your other wheels too. For a typical three-point undercarriage, you'll end up with something between 6 and 9 smoke entries.

Tha last step is to create a simple bit of xml that you call from your panel.cfg file. The xml gauge would simply read your ground speed, and trigger each of the numbered smoke effects as you reach certain speeds. (The gauge would probably also need to check what ground type you were on...just in case you don't want to kick up dust if you move from dirt onto tarmac.)

As I said. there are probably other ways of doing what you want to do, but I had good success using the above method to give increased propwash effects as engines were spooled up on wet tarmac, so the same principle could be applied to wheel dust.

If you want, I can give you some of the xml I used for the propwash effects which you can play around with for your dust effects? Just let me know.
