Umm, hello, I just wanted a tutorial on how to import 3D Obj file to 3D mesh then to render it. I already made a 3D engine following Codingbio’s tutorial, but does anyone know how to import obj like ggenji 3D engine or other engines? Thanks. Here is the link:

Pretty sure you can't do that at all unless you make an INCREDIBLE amount of code to load them. Don't even get me started on importing them to Scratch.

The obj format is both simple and easy to parse using scratch blocks. Since the format consists entirely of text, you can look at storing it either in a list or a variable and reading line-by-line or character-by-character.

The Wikipedia article is sufficient, it is what I used: https://en.wikipedia.org/wiki/Wavefront_.obj_file

@awesome-llama I know you need to put data in list, but how to decode the data in lists? Do you have any example of how to do this? Tutorials with visual aid I like. Can u give me instructions?

add [I know but how?] to [message v]
