Connecting to server crashing Blender 4.0 on MacOS

[satishgoda]

Hi.

I am on a M2 MacBook and I downloaded the latest Blender plugin. I am able to start the server, but when connecting to it from the app, Blender crashes. Following is the trace report after crash.

Hi.

Happy New Year 2024!

Just checking in to see if a plugin update for Blender 4.0 will be made available.

Thank you!
Satish.

Hey, Happy new year guys.

Reporting same issue. I just installed last version of the add-on and it made blender 4.0 crash when enabling live preview on my iPhone. Same iPhone with same iOs worked like a charm on 3.4.1.

Following the crash I can't even launch back blender 4.0. Icon bouncing on the dock forever.

Have the same issue here on my Macbook Pro. Blender 4.0 crashes when I try to load the live preview. Connecting works fine, but once I hit the preview button, Blender crashes and takes a strange amount of time to reopen. This same iPhone works perfectly fine with my PC.

This also occurs on Windows.

I really hope that this project is not dead. Would love to continue to use it with Blender 4+. Thanks you.

Hello @satishgoda the project is not dead :)
There is a Blender bug that needs to be solved before I can properly debug my code. I need the Blender Buffer to work properly for screen streaming.
https://projects.blender.org/blender/blender/issues/116551

I'm looking for reliable workarounds, but so far all of them provide a poor, slow viewport experience.

Thank you for the response @shycats. Thanks for all your work.
Do let me know when things are ready for testing and happy to help out!
