Bevy version

v0.5.0

Operating system & version

Debian/testing

What you did

  1. Ran cargo run --example load_gltf -- observed helmet rendered in the window.
  2. Opened Wings3D
  3. Imported FlightHelmet.gltf into the scene.
  4. Exported the scene back to FlightHelmet.gltf
  5. Ran cargo run --example load_gltf -- observed segfault without the model being rendered in the window.

What you expected to happen

I'm hopeful for full Wings3D compatibility but I'll settle for a more actionable error and controlled crash when the file cannot be loaded.

What actually happened

Segfault. Here's a backtrace:

Duplicate of #121 I think. There is a draft PR: #1795.

This is definitely a duplicate of #121. Using the blender steps outlined in that ticket's comment history allows me to load the model. I've also tested the #1795 branch and it allows me to load the Wings3D-exported model without the blender steps.
