Hi, in text example I saw this id: { size: 1, data: text.buffers.id }, I tried to check Geometry but didnt saw any usage of it, what is purpose of it ? its some built in attribute ?

thank you

Hi @hansagames, id provides a per-character index, for effects that may require it, such as having text that fades in letter-by-letter.
