scene.debugLayer.show() no longer working

Bugs

Invoking scene.debugLayer.show(); no longer works. No changes to the imports and it suddenly stopped working.

Error:

Ohhhhhh it sounds like a bad bug related to the content of your scene :frowning:

Is it possible to access your scene or to repro in the playground ?

I really want to tackle this on as a priority.

3

Also do you know when did it stop, it might help me checking into the changes.

4

I would say it stopped withing the last 20 minutes from when I posted. I don’t have a playground for it, it’s a local project.

5

So this would be our latest update let me check what changed in there which might be related.

6

There is nothing related to inspector in the latest change :frowning: Do you have the project online I could access ?

7

I unfortunately do not have it online. I will ping you when I put it online - but given your reassurance, I will dig in my code if anything is off.

Thank you

Actually, it looks working in the playground and sandbox but a bug in the inspector linked to your scene data (bug would only show in case of a special condition in the scene) is highly possible.
