Expression Direction Notes Settings Tab Function Note
F Forward Adding () after F sign will determine how long branch is. Values Angle Positions branched line.
+ Right Geometry Generations Will control the birth of the lines.
- Left Tube Rows/Columns Adds more resolution to the lines (points)
[ ] Start & End of a branch Adding F after [] will continue with the path before branching. Values Variable b, c, d Could be use to randomize values
( ) Sets Explicit Angle Value Comes before the letter
A None Nothing until you give it a Rule value
/ Roll the branch, separation Goes before the F letter
^ Downward bend Comes before the brackets e.g   ^ (20) they override global values
& Upward bend Comes before the brackets e.g   /(20) they override global values
! Tapering the Tube Which is connected to Tube Setting and its added before F sign or %^ Thickness Scale & Thickness TS - Taper (depending where you put ! sign), T - Overall thickness
^-(20) Random Angle values For curving out branches in random fashion.
J, K, M Placing Flowers on the tip of branches Which can be placed within the Rules.
Multiplies the Step Size Scale generation from Values Tab Comes before everything. And we use it to random the scale from bottom to top.
, Change a individual thickness of a stem Comes after the e.g.  F(0,007, 0,02)
stamp("../lsystem1/","lsys",0) Used with Switch Node input To add more geometry variations (e.g. leafs)
(L,0,1) Controling the input value of Switch Node Its added on the end of the branch as (L,0,1) e.g. [^CCCJ(L,0,1)]/(120)
(L,0,0) Controling the input value of Switch Node Its added on the end of the branch as (L,0,1) e.g. [^CCCJ(L,0,0)]/(120)
: Adding a probability of randomization Add this at the end of the Rule together with the number e.g. :0,5 which == probability of 50%
