VFX Mesh Generator Pro 2.7.3 – Production Stability Update

This release focuses on production stability, safer Unity/Unreal export, improved slash pivot workflow, and Blender 5.x compatibility.

Export & Engine Pipeline

• Fixed Unity export scale so 1 Blender meter correctly imports as 1 Unity unit.
• Improved Unreal FBX unit handling for the standard centimeter-based workflow.
• Removed legacy automatic x100 vertex scaling from the standard export pipeline.
• Added safer FBX unit and scale handling.
• Improved non-destructive export to preserve the original Blender mesh data.
• Fixed export pipeline fallback behavior that could produce files with incorrect axis or scale settings.

Vertex Color & Flow Data

• Fixed unwanted RGB vertex color data affecting material colors in Unity.
• Engine Safe export now keeps Vertex Color RGB white while preserving Vertex Alpha.
• Flow Map data now uses UV1 by default to avoid conflicts with Vertex Color.
• Improved cleanup of preview-only color attributes during export.

Slash / Sword VFX Workflow

• Fixed Slash mesh pivot placement.
• Slash meshes now use the arc center / character center as the default rotation pivot.
• Added Arc Center / Character Pivot support.
• Added a radial pivot guide for easier sword-slash alignment.
• Existing Slash presets using the old Center mode are handled automatically.

Production Tools

• Added Engine Data Layout presets for Unity, Unreal, Packed Mask and Custom workflows.
• Added Engine Data Validator.
• Added Batch FBX Export.
• Improved VFX-aware LOD validation.
• Improved export safety checks and reporting.

Stability & Maintenance

• Fixed missing operator registrations introduced in previous development builds.
• Improved add-on registration validation.
• Fixed Export panel UI issues.
• Removed invalid Blender UI icon usage.
• Improved Blender 5.x API compatibility.
• Refactored duplicated export code into a safer centralized export pipeline.
• Improved package structure and reduced unnecessary package size.

Recommended

• Blender 5.2 LTS
• Blender 4.5 LTS

For existing users, the default Engine Safe export profile is recommended for standard Unity VFX workflows.
