Clouds following terrain revisited

No, I don't think so, but maybe something has changed in the cloud node in the last years or so. I hardly ever (never) use those features nowadays. I will test some older file in which I did a very nice lenticular cloud. See if it still works.
If you try my file and fill in some other values, funny things happen.

So what you both say is that it might be a system dependent problem...? ???

For me it works on Win 8.1 and TG3.


Can you show us examples of your working versions? Like I mentioned, I thought it was working on my Arid Landscapes, but it only varied the tops of the clouds slightly, which may have just been depth modulators.

I was using a SSS and side view to see the whole push, if there was one.

So, I figured out (I believe) how to get this working for myself. What I did is a disp to scalar, divided it for some smoothness, than a colour adjust, -1000 black level and 2000 white level, both clamped. I than simply plugged that into the altitude adjustment. No difference, sure, than I headed into the cloud layer itself, and upped the Function Multiplier to a whopping 1500-2000 (in my scenes case) to get some effect. I haven't rendered this for a confirmation but it looks pretty obvious in the preview from the flat cloud layer cutting off the mountains half way up.
