Blender hangs with Lego 856 Bulldozer scene #207

Closed pablode closed 2 years ago

pablode commented 2 years ago

Tested with latest master (1.0.77) and Blender 3.0.1.

To reproduce:

  1. open Lego 856 Bulldozer scene: https://blendswap.com/blend/11490
  2. set Render Engine to 'USD Hydra'
  3. observe Blender hanging indefinitely

The following message is emitted periodically:

Hi.

Actually it works but requires a lot of time. Also, if you disable one viewport, render will finish much faster.

Yes, you're right, thank you!
