Question in planet studio

@HORIZONSPACEUK thx

DUDE IM SO SO SORRY i forgot to re-follow i thought i did. well now i have :)

@Zenithspeed ok thanks!

from my experience, expressions are the most complicated part of PS planet building, you can do lots of mathematical things, there's things like pow, smoothstep, clamp, etc etc
one thing that makes them infamous though is that messing even the slightest bit of the expression up will make your planet go all random, usually resulting in spikes, holes, repeated patterns, etc.
unfortunately there's no guide for expressions i know of, and even the built-in mini-guide barely talks about them
and really, i reccommend you stay away from them unless you use them for simple cases, i mean i consider myself a mid-high-end planet builder (below the likes of Ylias, eyov2, or chillymations, but above most others) and i still barely use them
