opened on May 26, 2026

Tested versions

REDOT LTS 26.2 BETA1, Win64 mono x86

System information

Windows 11 64bit, nvidia 5060GTX, 16mb Ram, CPU i5 14400f

Issue description

After importing a mesh with rig from Blender 5.0 in .glb format into Redot LTS 26.2 beta1, selecting the skeleton causes an immediate crash to desktop. This also occurs when loading projects from 26.1 or REX 0.02, and selecting the skeletons in their meshes.

Steps to reproduce

  1. Create new project
  2. Drag glb file into project. Then create a new scene, drag .glb file into scene.
  3. Right click new scene node, and select 'make local' to get access to the individual components
  4. select skeleton node.
