PS There is no .nod file for the Lsystem ? Only a js file ?

Edit : ok Found! :) Just put the JS file inside the folder (for PC) ...\Moi\nodeeditor\nodes\extensions\lsystem.js
Will be in the Node / Objects2 if i am right...
Insert 3 nodes "sliders" a an "OutPut" et voilà!

And so the .nod! ;) https://moiscript.weebly.com/uploads/3/9/3/8/3938813/lsystem_pil.nod
and the site ;) https://moiscript.weebly.com/objects2.html#lsystem

Absolutly terrific! Bravo! Another infinite toy!
