From Marcus ( mpo910)

In the volumetricclouds.cfg there are settings for each cloud type and global once.

Try at l cumulus and cumulonimbus the section persistance=0.63 instead of 0.95

Then increase at the global section edge noise wavelength to 2.7 instead of 2.5. this should lengthen the edges more and looks less edged by increasing this value.

The persistance is responsible for the small noisy parts around the cloud scapes witch also look to pixelated in my opinion. Reducing the value makes less of those persistance parts so less pixelated also.

This has no performance impact.

Thanks for forwarding Gerard.

Marcus is this the same one you posted at HiFi forum?

Thanks for your help with these ea clouds.

Yes it is. 

[mikeymike 360]

and why couldn’t LM incorporate sliders in the main menu for these to be adjusted?

i believe I’ve seen that in a video for truesky.

cheers

Thanks Gerard, I‘ll try tomorrow.

Is it correct that there as always the same coverage of clouds as far as you can see with EA? So no areas of better or worse weather?

Here I use FSGRW and I see differences when looking left and right. See my vids.

You're correct. There seems to be some confusion here regarding the spatial uniformity of the clouds with the EA option active. While it's true that LM has not implemented trueSky weather regions, all this means is that the weather is uniform in the horizontal plane. However the clouds are not. For a given cloud layer, the cloud type is fixed, for example cumulus.

But trueSky randomly creates cloud patterns (as Gerard pointed out above) and the clouds not only move with the wind, they also form and dissipate. Where it gets dodgy is when P3d5 creates overcast conditions. As individual clouds are packed more tightly, the random spacing in the vertical plane is lost leading to unrealistic gridding when viewed from altitude.

Should i use your setting or AS rc4 with New setting ?

[ark4diusz 324]

It seems that in AS RC4 the problem with pixelated clouds is fixed. For me still the problem is orange/light red sky colors in certain conditions... Does anybody also have this issue?

Yes. We ALL have this. Because this is TrueSky settings which we are not able to tweak/tune at the moment. Only LM can.

Post at LM Support here:

[AnkH 2,261]

Still get those pixelated clouds all over the place with AS RC4... will try those settings...

[MichaelLowl 63]

Shut EA down. Momentarily the only way to expect the potential of AS RC4.

I went back to the default VolumetricClouds.cfg file as it gives me least grid look with an OC.

That is icw FSGRW, so not AS. Unfortunately AS is not able to sent weather to more than 1 view pc from a client pc. Or from 1 view pc to the other.
