Hi @Arash_Bagheri
Please don’t create multiple topics for the same issue.

Why don’t you use @nasimiasl solution by injecting a NaN value when the ID changes?

Hi @aWeirdo
sorry for making another topic, because I did not get any useful way.
the line array in my PG was just a sample array, and I need a Practical way when I wanted to use json file, I can’t change the json file to NaN , and as I said I need to find a way for more than 1000 points.

Agree with @aWeirdo about multiple postings.

Is something along these lines more like what you are after? https://playground.babylonjs.com/#FRJX06#15

Note use of CreateLineSystem rather than CreateLines.

Hi. For what purpose you mix metadata of line and points data? You need
linesystem: [
Line:{
Points: [
[0,0,0],
[1,1,1],
Etc…
],
Metadata: {
Metafield: meta
}
},
Line: {…}
]
