Hard cloud edges in valleys

Are those default weather and clouds?  What are you using for those?

I ask, because I haven't noticed those types of hard edges in P3D with ActiveSky and ASCA and PTA going.

Yes I have ActiveSkyP4 with ASCA and RexSkyforce3D and EnvShade/Envtex all running.

No PTA.

It's been like for as long as I can remember. It's a limitation of 2d clouds unfortunately.

You can rotate them in the air to make them look 3D, but as soon as they clip through the ground they look a 2D picture intersecting 3D terrain and the illusion is lost.

Any ideas how this was done then?

He says Tomatoshade. I use PTA. Anyone know if this is something TS can do which PTA can't, or is this blatant Photoshopped misrepresentation/dreamland? Cos I'm not seeing any hard lines up against those hills.

It's a combination of luck and angles. Just like most good screenshots are 😉

 I use PTA and ASP4 and between Anchorage and Fairbanks, when there are clouds, it looks almost identical to the screenshot above. The issue is not a shader issue. You may want to post on the Active Sky forums, if I remember correctly, this subject has come up before.

Cheers, I'll have a look over there.

I use ASP4 and Envshade - that's what I see in those cases. I have volumetric fog enabled.

Me too, but I'm getting hard edges. Horrible.

the hard edges occur when there are cumulus clouds intersecting with the mountains, it looks fine with stratus type clouds and fog.

I don't know if this suggestion will help but AS has a setting to positively offset cloud elevations. Some of the "hard edge" issue stems from AS interpolating METARs in mountainous areas and subsequently placing the lowest cloud layer such that it intersects with the terrain. Often, the volumetric fog hides  the problem but not always.

I specifically set up a low level cloud layer with stratus to test this, but it had the same problem.

The effect can be achieved without any cloud layer. If the mountain top is 5000ft, in the Advanced Weather, delete all the Clouds layer, then set the Visibility layer 'Tops' at around 4500ft, and 'Visibility' at 2mi. You also need to turn on Volumetric Fog in settings.

Yup. That works. Thanks.

My problem is that I use ASP4/ASCA and the effect doesn't work properly with that so far as I can see. I can't see a way to just make a volumetric fog layer with it. It only offers making cloud layers, then seems to mess with visibility settings to make haze etc, but not a proper fog layer. Unless I missed something, but I've been through all the settings and options.
