[HOW] can I make part not appear to be silver

[Bouni]

What do you want to achieve?
I render my PCB sucessfully using blender_export. however, some components appear to be silver or some sort of metal. Can I somehow define a color that should be used for certian components?

Do you have some PCB/Schematic to use as example?
This is what I see in the 3D viewer in KiCAD

And this is what I get from the blender export

K1 and the connector seem to be silver

Do you have some configuration file (.kibot.yaml) that you are using?
You can attach it or paste the content in the following section:

  - name: "PCB 3D Blender image"
    comment: "3D render from top (High Quality)"
    type: blender_export
    options:
      render_options:
        background1: "#8FBCF7FF"
        background2: "#0B1E35FF"  
        samples: 20
        resolution_y: 1440
        resolution_x: 2560
      point_of_view:
        rotate_x: -5
      outputs:
        - type: render
          output: "Oberseite-3D.png"

Environment (please complete the following information):
Where are you running KiBot:

• Gitea actions, INTI-CMNB/KiBot@v2_k9

Hi @Bouni !
Are the 3D models from KiCad? I guess they are custom ones.
Are the 3D models only in STEP format? You should provide WRL and STEP

If you are using custom 3D models you'll need some work on them, use FreeCAD and the StepUp to create both versions of the model. You can choose how colors are mapped when creating the exported models.

They are both STEP, the relay model is from JLCPCB, the connector model is from Molex.
I'll try to change colors using FreeCAD.
