Trying to render +500 3mf files i've colored in bambu slicer in blender.

I'm unsure what I can do for your issue ... creating a blender plugin or script is definitely out of scope for this project. You could use this project to render your 3mfs, but for 500+ files it might be quite time consuming, which you could automate with tools like Puppeteer or other browser automation tools.
But I might be misunderstanding what you are communicating - please give more details to your issue

So basicly what i'm searching all internet for the past week is:
I want to import 3mf files created by Bambu Slicer which i've already painted.
As far as I can see, the face/triangle/vertex color values are protected.

I want to see if it's possible to control that paint_color values to convert into vertex color/faceset data basicly.
Maybe i can continue from there with the automation.

I've tried to understand x3d, wrl, ply (xml basicly), but couldn't figured that out as i'm not a programmer. Just a hobbyist!
Thanks for your reply by the way!

Edit: And maybe dividing same "paint_color" faces into vertex groups could be possible with a smallish script?
