Reviewing and Debugging 3DTiles Geometry in RenderDoc

CesiumJS
1

Hi, Is it possible to connect CesiumJS to RenderDoc to review and debug the mesh information in a scene. I’ve successfully connected RenderDoc to my app but I don’t seem to be able to view the building geometry in my 3DTiles following a capture. Steps to reproduce:

  1. Command line instruction to configure RenderDoc for capture:
set RENDERDOC_HOOK_EGL=0
  1. Command line instruction to connect to app and display process PID (Don’t click OK in popup):
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://localhost:8080/ --disable-gpu-sandbox --gpu-startup-dialog
  1. Inject process in RenderDoc.
  2. Press ‘OK’ in PID popup.

I was expecting to be able to see the meshes from the capture. I was also hoping to determine whether object IDs and any semantic properties were visible as this could be a security issue if sensitive information is linked to those geometries.

After further investigation the 3DTile geometries are visible by expanding ‘Colour Pass #2’ and ‘Colour Pass #5’ items in the RenderDoc event browser. The IDs and Semantics associated with the geometries do not appear to be referenced in the RenderDoc output.
