Thanks guys. The round rocks are soft dots being pushed up, then a small patch compute terrain, then lateral and further normal displacement to bulge them. Mixed with some normal fake stones and 'fake stone' sand. The further away limpets are smaller dots displaced 3.5cm, but I wasn't able to get them all 'limpet colored', as masking them by themselves (same hardened dots) excludes the tops obviously, if they're too high.
@ Doug; no, it's not a series of new experiments. If I need something, or get some idea) I open a new TG session and try some stuff, and often add some more things just to make it a bit nicer. It grows, so to speak, out of hand
Like, raising the dunelike shore after having made the round stones (soft distance shader, black upped to have no round stones on gradual 'beach'), it reminded me of something like Namibia, and I thought, why not put an abandoned train there. Some sand on it and some tiny bump to get it worn. Oh yeah, and a some local Daniil erosion to get certain areas of sand a bit lighter (wear mask). I'm a bit limited in time now, but if I can spare a few hours, I like experimenting.
