This is a sort of continuation of MayAvali's guide, as I will be using their guide throughout this one.

As SST has a pretty complicated UI, this guide aims to help clear up what any of these settings do.
I will only focus on the Planet material setting for now, but I may do the others in the future.

The official name for the particles are "nodes"

Material IDs:
1 = Earth
2 = Water
3 = Fire
4 = Air
5 = Lava
6 = Ice
7 = Vapor
8 = Stone
9 = Plant
10 = Oil
11 = Smoke
12 = Metal
13 = Sand
14 = Plastic
15 = Solar Panel
16 = Acrylic Glass
17 = Laser
18 = Rotor
19 = Jet

0 = Default (unused, unstable, tends to crash game if not deleted quickly)
-1 = No material/no change
-2 = Whatever material the atom was before it switched to the current one (used in lava)

change_material - Allows the selected material to replace other materials.

draw_platform - The selected material (if given a positive, relatively high max_stuck value) will be drawn stuck in place until environmental conditions force it out.

cdist - How far apart the particles are placed from each other.

draw_pinned - If checked, will prevent the placed particles from ever moving.

colour picker - The colour of the particles.

mass - The mass of the particles.

cpow (c power) - How strongly the particles will repel other particles when too close.

cdist (c distance) - How close particles will come to each other before being repelled.

csize (c size) - (unsure)

csizemul (c size multiplier) - Multiplies how much particles will grow when heated.

damp (dampening) - Provides inertial dampening on particles.

attr (attraction) - (unsure) How particles attract towards each other.

xeno - (unsure) Pushes apart particles with different properties.

lpow (link power) - The power of a particles bond or link with other particles.

ldamp (link dampening) - How strong the elasticity of the links are.

sangle - (unsure)

add_linked - Determines if particles are allowed to link to each other.

lrobust (link robust) - How far a particle's link to other particles can stretch before tearing apart.

arobust - (unsure)

magnetic - How strongly the particles are attracted by magnets.

gravity - How much gravitational force the particles experience.

hdiff (hue difference) - How random the colour of particles are.

tdist (temperature distance) - (unsure) The distance of links.

tdistmax (temperature distance max) - (unsure)

tpow (temperature power) - (unsure)

tpowmax (temperature power max) - (unsure)

tcond (temperature condition) - (unsure)

add_temp - (unsure) How much energy is needed to heat up a particle.

cde_heat - How much heat is released when a link is broken

tphase (Temperature phase) - [low temperature limit, high temperature limit]

mphase (Material phase) - [material ID to turn into when low temp is reached, material ID to turn into when high temp is reached]

vphase (Valence phase) - [minimum # of connected atoms, material ID to turn into when # of connected atoms is lower than the minimum]

bphase (Bio? phase) - Unclear, function doesn't seem to do anything (at least in planet mode)

sticky - Determines if a particle can link with other materials by touching.

chemical - Determines if a particle will link with its own material by touching.

maxValent - The most links a particle can have.

actValent - Determines if a particle will actively link with particles (when it's 0 the particle will not keep links).

max_stuck - How strongly the particle is stuck to the background after being still for some time.

lifetime - How long a particle will exist before deleting itself.

tfire - (unsure) [what temp to burn at, temperature of the fire particles, how quickly fire particles are made, how long it burns]

mfire - Determines what material the fire is made of.

[SOON]

add_aqua - How quickly particles absorb water.

aqualize - Determines if particles should absorb water.

aquacap - How much water a particle can store.

aquacond (aqua condition) -

vaporize -

electrocap - How much electricity a particle can hold.

electrocond (electro condition) -

electroheat -

electrophoto -

electrophotomass -

electroforce -

electrotonus -

control -

racap (ray capacity) -

racond (ray condition) -
