Description

Environment

Second Life Release 7.2.0.16356654553 (64bit)

Description

Checking "Include joint positions" in the Upload Model>Rigging tab is adding a Z offset to the model preview.
Checking "Joint position overrides" under the model preview also adds this offset.

This Z-offset is not included upon uploading and wearing in-world.

Reproduction steps
  1. Go to Build>Upload>Model and select the rigged angel model: https://github.com/user-attachments/files/20986217/angel_rigged.zip
  2. Toggle the "Include joint positions" and "Joint position overrides" checkboxes

Research direction

Start in the Upload Model > Rigging workflow and reproduce the issue with the linked angel_rigged.zip model. Toggle “Include joint positions” and “Joint position overrides,” then compare the preview’s Z position with the model after uploading and wearing it in-world; done means the preview no longer gains the unintended offset.
