Features

• Blender Scripting - Implemented as a suite of Python-based Blender add-ons to automate mesh and armature operations.
• Avatar Optimizations - Provides a specialized pipeline for optimizing character polygon counts and textures for VRChat avatars.
• Skeletal Structure Optimization - Optimizes model structure by reparenting bones, removing unnecessary joints, and combining materials.
• Avatar Import Pipelines - Brings models from formats like MMD and Mixamo into Blender with corrected normals and naming.
• Avatar Pipeline Automation - Automates the process of preparing 3D models for VRChat by coordinating polygon, bone, and texture optimizations.
• Armature Merging - Combines multiple armatures into a single base structure and aligns meshes via transformations.
• Avatar Format Import and Export - Loads and saves models from various formats using optimized settings for compatibility with target environments.
• Blender Add-ons - Implemented as a suite of optimization plugins that integrate directly into the Blender environment.
• Shape-Key Preserving Decimation - Reduces polygon counts while calculating and projecting the new geometry onto existing blend shape targets.
• Mesh Optimization - Offers mesh optimization tools to reduce polygon complexity while managing shape keys for high-detail models.
• Texture Atlases - Includes a texture atlas generator that combines multiple images into a single sheet to reduce draw calls.
• Rig Cleanup - Removes unused bones and deletes zero-weight bones to simplify the character rig.
• Skeletal Rigging - Provides tools for cleaning skeletal structures and merging bones to simplify character rigs for real-time platforms.
• Skeletal Simplification - Simplifies skeletal structures by merging groups of bones based on a percentage to improve rendering performance.
• Transformation Baking - Bakes position, rotation, and scale of armatures and meshes directly into the base mesh data.
• Polygon Simplification - Implements polygon decimation that reduces vertex counts while preserving essential shape keys.
• Facial Animation - Implements facial animation setup including lip sync visemes and eye tracking for realistic character expressions.
• LOD Variant Generation - Creates simplified versions of models to maintain performance on lower-specification hardware.
• 3D Model Importers - Includes utilities for importing and cleaning 3D models from formats like MMD, Mixamo, and DAZ.
• Mesh Geometry Processing - Provides geometry manipulation tools for separating meshes by material, joining parts, and removing duplicate vertices.
• Automated Lip Sync Generators - Ships tools that automatically generate mouth shape keys for realistic lip-sync animations.
• Avatar Eye Tracking - Implements artificial eye tracking capabilities that allow 3D characters to look at nearby users.
• Bone Hierarchy Organization - Groups related bones under a single root bone to facilitate the use of dynamic bone physics.
• Pose Capturing - Captures relative vertex offsets from a character pose and stores them as additive shape key deformations.
• Rig Restructuring - Reorganizes armature parent-child relationships to meet specific technical constraints for game engine imports.
• Vertex Weight Reassignment - Redistributes weights from deleted bones to parent bones to maintain mesh deformation after skeletal simplification.
• Weight Redistribution - Merges weights from deleted bones into parent bones to maintain mesh deformation after simplification.
