Lost dust and smoke effects

Recommended Posts

Hi Steve, all.

 

I've lost dust and smoke effects from FSX - sometime in the last few weeks. I don't usually notice it but flew a Helo today and realised it was gone - no downwash dust and no engine smoke.

 

I then tried with my old smoky A2A Piper Cherokee - which very satisfyingly belches out plumes of grey/ black smoke - and that's gone too.

 

I installed the latest DX10 Fixer version a few weeks ago - that's the only thing that's changed in the sim.

 

Any ideas very gratefully received, thanks.

Have you accidentally turned off animated affects in FSX?

Hi Len,

 

Yes thanks, Advanced animations is checked on  the main Settings page.

Is Convert Effects ticked in the DX10Controller Lights/Effects dialog?

Well try a test switching to dx9

 

Did so Steve, both in DX9 and DX10 the smoke, contrails and vapour are all there but only viewed from a certain range of angles on a revolving view around spot. So, for instance, smoke and contrails and vapour all there between 120 and 200 degrees but then, panning round in spot view, they vanish from 200 to 260, then reappear from 260 to 310, etc. Weird, I know.

 

I don't actually think this is a DX10 Fixer issue but I'd love to know if you have any thoughts on why this is.

uninstall the fixer libraries and retest - it should be adjusting particle effects so I don't see how it can be the issue, but lets be sure.

Then if the problem still exists is this with a specific aircraft or generally e.g with default Cessna?  Does it occur with spray on a wet runway in dx9?

Tried uninstalling libraries - no difference - still as above.

Then I switched to dx9 and the problem is still as above with snow/ rain on runway.

Ok look in the aircraft.cfg and confirm that water in the effects section is set to fx_spray, then tell me what the various particle face attribute is set to in fx_spray.fx.

Glad I found this tread because I have the exact same problem Steve.  I installed the latest DX10 fixer with the updated Cloud Shadows a few weeks ago.  Since then, no smoke effects or viewing angle specific as described here.   Testing w/o cloud shadows turned on.

Well to be clear so far I believe that we have proved it's nothing to do with the fixer, as it doesn't touch the problem effects... and the problem occurs without it in dx9.  

 

Nonetheless I shall persevere until we understand the issue, it sounds like a face issue tbh, and the fixer does edit the face in effects but not particle effects and not when you switch to dx9.

Well something happened.   Not a single aircraft or rotorcraft shows particle effects, smoke, spray....etc.  Running Windows 7, 64 bit.

The Fixer is uninstalled. No particle effects enabled as a result.  Very strange.  I wonder if more folks will run into this.

Yes, and my particle effects are fine with and without the fixer, i am waiting for the OP to confirm that an aircraft with missing spray is using the original MS fx_spray.fx and show me the particle definition so I can see if it has been altered.

Thanks for looking into this Steve - even though as we suspect - it's not a Fixer issue.

 

So, yep, water=fx_spray in the aircraft.cfg

 

and in the fx_spray file the attributes are:

As far as I can see, that is identical to what I have - i.e exactly as in the original install, so the fixer (correctly) hasn't edited it. 

Its worth checking that the textures exist  fx_1.bmp  and fx_5.bmp  but I don't see how they could cause what you describe.

You are certain that in DX9 you can only see dust from some angles? 

Are you using a camera addon at all?  

The way that fsx draws effects is a technique called billboarding.   For each particle it  creates a square, then rotates it to face the viewpoint and then samples the texture (which will have transparency - so you don't see the squares (unless in dx10 a texture is missing).   Now that rotation  happens in the fsx core code not in the shaders.

Here is some spray without textures so you can see the squares, note that they all face the camera.  Those in the foreground  are cutoff by the ground.

Bit of a breakthrough I think Steve,

 

I went back to DX9 (god, does it look awful after DX10) and disabled Orbx Region England and voila! dust kicking up, smoke, etc from all angles. I wonder if this is a graphics card issue - GTX780 - with the buffer filling up and going wonky. I also looked at a few Youtubes of this particular aircraft - Razbam Harrier GR7/ GR9 - and by the looks of things the smoke only appears at the same angles for everyone. So I'm happy to leave things alone but many thanks for your help.

 

Changing the subject completely, if I may; I use the above aircraft a lot and I would love to be able to use Crazieman's ENB Russian Bloom Night Vision Mod (info here:  http://www.hovercontrol.com/cgi-bin/ifolio/imageFolio.cgi?img=0&search=nvg&bool=phrase Is there any way I can do so - or any way of simulating Night Vision in DX10 as Night Ops await?

GPUS aren't that clever, they just see millions of triangles, they cannot choose to drop spray and keep the aircraft as they wouldn't know which triangle was which!

I think that there is some throttling of effects inside fsx  so that might be occurring, but why orbx would be drawing lots of effects I don't know. Have you updated their libs recently?

Ahhh, this is doing my head in - they've gone again!!!

I loaded back in to DX10 via the Fixer and started up with no Orbx scenery at all. Not a puff of smoke even on engine start. Usually the Harrier will kick up dust - same as Helos - on lift off and land - nothing. Is it time to repair FSX from the disks - what will be the connotations for the Fixer if I do.

 

Desperate to get the old Harrier belching smoke from those vector nozzles!

Try an airport in Mongolia to rule out any scenery ( I assume you are unlikely to have any Mongolian addon!)

Ok, just returned from Mongolia! Sorry I didn't bring you any Yak products. No smoke, no dust no nothing.

 

So that's scenery out then.

We have big smoke in DX9! From all angles and all cameras. Luverly!

It's such a disgusting polluting aeroplane - I love it.

So in summary I suppose; full smoke (all cameras/ all angles) in DX9 and only reduced smoke (not as full on/ fainter) from certain angles and cameras in DX10.

Smoke also is directed correctly according to Nozzle angle
