[BUG] Blender output does not create a PNG

[Informaticore]

Describe the bug Render Blender PNG is missing. In my yaml file I am using:

outputs:
  - name: 'Blender 3D Image'
    type: 'blender_export'
    dir: 'Generated/render'
    options:
      point_of_view:
        rotate_x: 45
        rotate_y: 45
        rotate_z: 75
      pcb3d:
        download: true
      render_options:
        samples: 100
        transparent_background: true
      outputs:
        type: render

the container I am using is: container: ghcr.io/inti-cmnb/kicad7_auto_full:latest

I have not touched the config since a while and with my commit some time ago it was generating that PNG

This job was running 3 weeks ago and the PNG was created: https://github.com/open-thngs/so-dimm-esp32-cm/actions/runs/5831095589

With this job today it did not generate the PNG: https://github.com/open-thngs/so-dimm-esp32-cm/actions/runs/6047189057/job/16410157210

@set-soft what else do you need? the output which is supposed to generate a PNG is not generating a PNG anymore. The project is there, what else can I tell you?

this is the yaml: https://github.com/open-thngs/so-dimm-esp32-cm/blob/main/esp-cm3.kibot.yaml this is the action: https://github.com/open-thngs/so-dimm-esp32-cm/blob/main/.github/workflows/kibot.yml

I'll try to look at your files later, you can provide the debug output, if Blender is failing you'll see the Blender error there.

This is the output from the action:

Hi @Informaticore ! In order to get the debug information you must use -v, or -vvvv for even more details. I think I found the problem, while I find a solution you can try changing latest by dev (1.6.4 development) or 1.6.3-1_k7.0.5.1_d11.6_b3.4 (1.6.3 release using KiCad 7.0.5 and Blender 3.4, assuming your project can be loaded by KiCad 7.0.5). The problem seems to be related to the pcb2blender upgrade.

KiCad 7.0.5 should work just fine, I am using 7.0.6 currently. I changed it to dev and it took a while (14min compared to 2) but I guess thats fine and might be related to actually render the things. Now it created the PNG

Yes, the render for your board is slow. Most probably because of the ESP32 module.

[set-soft]

Ok, now latest should work.

I'm moving this issue to kicad_auto_test because this isn't a problem on KiBot, but in the versions mixed inside the docker images (v1.6.3 doesn't support pcb2blender 2.6 without a small patch, the author renamed a parameter)

[set-soft]

The 2d7a7395a31fd5e6a5a95c00e3f55a6f93d9c7b9 and 91a84f037ce15db73cc4ad4fb9d6cd2b5f761adf commits patches v1.6.3 to work with pcb2blender 2.6
