Is this how REX4 & ASN clouds should look like in P3D?

Recommended Posts

Hi All,

 

Been working through setting up P3D v2.4 on my system and one thing I'm noticing pretty frequently is the cloud formations in P3D when using ActiveSky NEXT for P3d and REX4 themes are presented very differently than what I've seen in FSX. Here are a couple of shots to show what I mean.

 

 

Take note of the clouds in the upper right hand side of the screen shot.

This is one of the more frequent views I see when flying. It looks like it's the same cloud texture repeated over and over with no other variation presented.

Here are my system specs:

  • Intel i7-4930K 3.40ghZ OC'd to 4.5Ghz
  • 16GB Corsair Dominator GT DDR3 2133MHz CL9 Quad Channel Kit
  • eVGA GeForce GTX 780 Dual Classified w/ ACX Cooler
  • Asus Rampage IV Extreme w/ DDR3 1866, 7.1 Audio, Gigabit Lan, PCI-E, 4-way CrossFireX / SLI
  • 1X 250GB Samsung EVO SSD for my OS and 1X 500GB Samsung 840 EVO SSD for FSX and P3D
  • Windows 7 Ultimate 64
  • Corsair AXi Series AX860i Digital Modular Power Supply
  • Corsair Hydro Series H100i Extreme Performance Liquid CPU Cooler

Here's what I have running for P3D

  • Prepar3D_v2_Academic_2.4.11570.0_Full
  • REX4 Texture Direct 4.3.2014.1210
  • ActiveSky NEXT for P3D build 5410
  • Orbx FTX Global

Definitely not!  Did you actually install the textures from REX?  That would be the first thing to check.

 

Thanks for that tip. I checked in my Prepar3D v2\texture folder and can confirm REX is installing the cloud/environment files.

Try a different weather set, and different location.

 

Try deleting shaders also and increase cloud thickness using custom weather.

 

This happens on the odd occurrence, I think you can also set some settings in ASN for what kind of cloud coverage you get which may help.

Try not using ASN and load static weather from P3d. If all looks good... Look in your ASN settings for parameters that can affect sizing and doubling of clouds... I recall there were some options I'm unable to verify at the moment.

Gents,

 

Thanks for the tips. Here's the follow-up from your suggestions:

 

 

Try a different weather set, and different location.

This happens on the odd occurrence, I think you can also set some settings in ASN for what kind of cloud coverage you get which may help.

 

1 - Tried a few different weather themes (2 created from scratch) - no joy

2 - I delete the shaders folder every time I install a new weather theme or make a change as I tweak - no joy

3 - Reset ASN back to defaults and re-ran all my tests - no joy.

 

 

Try not using ASN and load static weather from P3d. If all looks good... Look in your ASN settings for parameters that can affect sizing and doubling of clouds... I recall there were some options I'm unable to verify at the moment.

 

1 - I ran P3D without ASN and used the "stock" weather themes - no joy

2 - I ran P3D with customized weather - no joy

 

 

The interesting thing is as I'm flying through the clouds, they look great but as I climb and they fall further below me, this is where the visual "issue" becomes more pronounced. At FL310 the clouds look like the images I posted above but if I'm climbing through them of cruising just above them, they look properly sized. It's like P3D stops sizing the clouds after a certain height.

 

Thanks again for the suggestions!

 

Mike

That looks oddly like the cloud sizing issue that used to affect some of us in 2.3. Did you do an upgrade to 2.4 Mike, and are you sure the upgrade took?

If you can provide location and altitude and date/time, I can test.  I have ASN, Opus, FSGRW.

 

Cheers, Rob.

Thanks Dylan. I purchased P3D v2.4 and did a clean install so no previous versions existed before I purchased. I did however, download the cloud.fx fix file from one of the posts here so I wonder if that may have something to do with this issue I'm seeing. I made a full back up of the initial P3D install before I installed any add-ons so I'm going to try and pull the cloud.fx file over and see if that makes a difference.

Thanks Rob. I'll send you all the details once I get home from work. Did you also want the REX theme I'm currently using?

Sure, I have REX 4 with latest SP and their soft clouds which I'm really enjoying.

The clouds in 2.3 were bigger not smaller... its only since the sizing-down that you get these puff balls when cumulus are placed at high altitude.

 

Resize the clouds by 100% and they look much better, but impact performance, and cause issues where they hit the terrain.

I have the exact same issue....I have been trying to fix it for over 2 weeks.

 

I patched up to 2.4 I dont have a full clean install....do you?

 

I have ASN and REX4 I am getting the same looking tile effect and have posted this in the LM forum as well. I also see them at the same time....when at higher FL's

 

Did you get a good workaround with any other of your tests?

 

its really getting anoying....first verticle clouds now tiles!

Ditto - also have this problem. Have seen it several times at various locations around europe. Next time i encouter it, I'll provide the loaction etc.

Ran some tests, I can't get my clouds to look like that?  The closest I got was using Scattered 3/8 4/8 or Broken 5/8 6/8 using a Cloud Density setting at Medium but they never looked as "organized" as your image ... I tried cumulus at 2000-5000, 4000-10000, 14000-20000 ... flight was between FL310 and FL330.

 

Quick video - isn't as bad as what you are reporting ... but I tend to agree a "little" more randomizing would help.  I haven't tried with ASN ... I was using a custom weather setup.

Rob, thank you for taking the time to look into this and sharing your results. It looks like mine and others are acting a little differently (i.e. more tiles)

 

I'd call my tile effect a dramatic & noticable one. Are you useing REX4 or Soft clouds in this clip? Have you patched up to 2.4 or clean install?

I did some more testing using OpusFSI this time around ... flight was from EKSB to ENTC.  

 

The clouds seemed good on departure, but after about 1 hour into the flight the clouds started to get very narrow and repetitive similar to the results shown by OP ... I recorded the issues and will pass along to LM.  

 

Also, I was getting cumulus clouds at 31,000 ft?  Checked METAR and it says scattered clouds 6200 to 12,000 ft.  

 

I also noticed a strange dark patch on the ground/sea (didn't look like a shadow) rotating with my view at FL310.

 

So not really sure what's going on ... perhaps the LM cloud changes have impacted how various weather engines build the weather or maybe it's just a bug LM need to look into.

 

I'll keep testing with ASN and FSGRW using 2.2, 2.3, 2.4, 2.4+"cloud fix 2" -- I hope I don't have to keep doing 1+ hour flights before I see the issues.

 

Cheers, Rob.

Here I have seen the same issue . After more than 45 min with Opus the overcast started to look like many the same clouds.

I thought that it was caused by Opus , so payed no attention to it as I always use ASN ( installed on the client pc ) on full simulator flights.

Here is why...

 

In the screenshot I used a cloud texture with characters and numbers.

For demonstration purpose :)

 

In FSX or previous version(s) of P3D the puffs would randomly be rotated around

the z-axis before placed in the scene. Which means for the screenshot there would

hardly be a character (or number) standing upright. An A could be upside down e.g.

And a 2 could be laying on its side etc, hope you get the idea.

 

As you can see now everything is standing upright which means for the clouds in

P3D2.4 that there basically are only 16 cloud puffs to draw the cloudy sky's from

and therefore the duplicates are easier spotted, depending on the shape of the

puff/cloud.

 

I for one, I like it how it is now (be it intentional or a bug)

The cloud tops can be painted now as well as the bottoms. It takes a bit of a

special painting technique to avoid repetition and especially stratus type can

look much more realistic now.

 

In the cloud.fx shader file things can be improved a little by changing line

293 into:

 

GetScreenQuadPositions( quad, width*0.7, height*0.7 );

 

(makes the puffs slightly bigger and the clouds therefore less repetitious)

I had been running a patched version of 2.3 and installed 2.4 and lost my puffy clouds, only a  very high level cirrus.  I ended up reinstalling (12+hours later) and now everything looks normal / great.

 

I also had REX4 and ASN and tried a couple of the recommended "fixes", but only the reinstall worked.

 

This seems to be a common problem...

Folks,

 

Thank you everyone for sharing your experiences and for helping out and apologies to Rob for taking a bit to get back to you on this.

 

I've been testing various REX themes and settings within ASN and P3D and like many others, feel like this is more to do with how P3D is now interpreting the weather being injected and also how P3D is generating the cloud formations. Some themes I tried worked better than others (not as a noticeable repetition) and one set seemed to work but the cloud coverage killed my FPS (from steady 30 to around 5 to 9) but I'm still testing as I think it may have been more to do with a Control Panel tweak I added versus the clouds themselves. Here's a video of one theme I used:

 

 

Here's my P3D and REX4 settings and the REX4 theme (shared out so you can download it and try as well) used in the video above. I think Rob is correct in bringing this forward to LM and Gerrit may have proven this is just how P3D now manages the weather environment in v2.4 so now the focus is moving to actually flying from point A to B versus trying to fix the clouds :-)

Gerrit,

 

Tried your suggestion and moved it up a notch higher to .80 for both width* and height* and I'm liking what I'm seeing so far! Took a test flight out of Spokane, WA with the following weather from ASN

KGEG 021759Z 00000KT 3SM -SN BR SCT022 BKN045 M07/M08 A3008 RMK AO2 P0000 T10671078

 

Even with the increase cloud size and snow I was able to maintain a steady 30FPS. There were some small dips to 24 but other than that, the visuals are much better and it's still smooth.

What I have found is right off the bat I saw the popcorn clouds after loading soft clouds - what I did was to go into user defined weather customize menu in P3D - I played with those settings until I saw some nice cloud coverage - play with type of cloud and 3/8 - 7/8 area - after I did this my basic themes of choice now look decent - it was like a switch or something

So is there any conclusion as far as who needs to touch on this? REX, ASN or LM?

Yup REX Soft Clouds work for me - also made the 7.0 change - thanks for that - this was just an Orbx theme - great stuff REX
