What's New
Home Screen
-
Quickly access recent files and discover dynamic content, including tutorials and support articles.
-
Multi-selection and rotation of joints: Edit multiple joints at once using Shift to add selections.
- Symmetry mode: Rotate one side of the avatar skeleton, and the other side adjusts automatically for symmetry.
- Mirror Joint Rotation: Apply mirrored joint rotations for selected joints.
- Select Hierarchy: Quickly select a chain of connected joints, useful for manipulating fingers or mirroring multiple joints (e.g., selecting an entire arm by hierarchy and mirroring).
- Copy-Paste Settings Dropdown: Transfer all rotation values (X, Y, Z) from one joint to another.
- Known Issue: Some avatars may display asymmetrical poses when using Symmetry Mode or Mirror Joint Rotation, due to skeletal structure inconsistencies.
PBR Material Improvements
-
Automatically generate Specular Level Maps to ensure fabrics are rendered realistically and maintain consistency in exported 3D files.
-
The Material Editing Menu has been reorganized to align with the standard Metalness/Roughness PBR Workflow.
YKK Metal Finish Presets
-
Predefined YKK Metal Finish Presets can now be applied to 3D trims for a more accurate representation.
Export Colors of SBSAR Materials to Tech-Pack
-
Ensure SBSAR material colors are accurately displayed in Tech-Packs to align with industry standards and improve collaboration.
GPU Troubleshooting Detection
-
Detects hardware limitations and provides notifications on operating system settings that should be adjusted for an optimal experience in VStitcher and Lotta.
Tech-Pack Improvements
-
Full Pieces Layout Export for All Sizes: Each size is now exported as a separate PDF file and stored in the Tech-Pack Folder (not included in the Tech-Pack layout preview).
- New Option: Remove Piece ID from exported PDFs of full pieces layouts.
- Artwork Page: Improved presentation of artworks and color names on Excel Tech-Pack.
