Instancing hierarchies with ResetXform #862

Open timthehoff opened 5 years ago

Instanced hierarchies containing resetXformStack evaluate differently than un-instanced references.

Asset hierarchy:

Xform asset
- Xform geo (resetXform)
  - Sphere sphere (translate [0, 2, 0])

Reference Example:

asset_0 (reference /asset) (translate [0, 0, 0])
asset_1 (reference /asset) (translate [5, 0, 0])
asset_2 (reference /asset) (translate [10, 0, 0])

This is the expected behavior, the spheres don't inherit the translations.

Instance Example:

asset_0 (instance /asset) (translate [0, 0, 0])
asset_1 (instance /asset) (translate [5, 0, 0])
asset_2 (instance /asset) (translate [10, 0, 0])

The instances ignore the resetXform and the spheres are translated!
