What's New

Home Screen

Quickly access recent files and discover dynamic content, including tutorials and support articles.

Symmetrical Avatar Posing

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.

Full Layout for All Sizes in Print to File

Export full piece layouts for all sizes, with each size saved as an individual PDF file.

Render with the Latest Version of Blender

Rendering now supports the latest Blender version (4.3) for enhanced output quality.
