JESUS
BLENDER 4.2 LTS • 5.0 • 5.1.1+ READY
WEIGHTFLOW PRO
Ultra-Fast Surface Weight Transfer • Auto Rig Detection • Game Engine Safe
By JESUS / JUSTVFX • For GTA V, FiveM, Unreal Engine, Unity & Cinematic Rigs
Stop wasting hours fighting messy vertex weights and mesh spikes!
Traditional weight transfer causes annoying weight bleeding between fingers, thighs, and clothing layers, requires endless manual clicks in Weight Paint mode, and leaves uncapped bone influences that break exports to GTA V / FiveM (Sollumz), Unreal Engine, and Unity.
WEIGHTFLOW PRO re-engineers weight transfer using Blender’s C-spatial acceleration (
WEIGHTFLOW PRO re-engineers weight transfer using Blender’s C-spatial acceleration (
mathutils.bvhtree & mathutils.kdtree), automatically scans your source rig's bone limits, projects live GPU viewport rays, and transfers weights in milliseconds with zero bleeding. ⚡ 1-Click Smart Presets
👕 Tight Cloth
BVHTree barycentric surface conform for shirts, pants, underwear, and skin-tight suits. Zero limb bleeding.
🧥 Layered Outerwear
Normal Raycast projection. Bridges heavy jackets, coats, and hoods without cross-surface jumping.
💇 Hair & Cards
KDTree K-Nearest search with Inverse Distance Weighting. Perfect for poly hair strands and fur cards.
🛡️ Rigid Armor
Assigns 100% influence to the single closest bone. Ideal for pauldrons, helmets, holsters, and weapons.
🧬 Topology 1:1
Direct index-to-index transfer. Instantaneous copy for identical mesh topologies, LODs, and blendshapes.
🚀 Core Professional Features
🎮 Auto Rig Scanner (GTA V / FiveM / Unreal Engine Safe)
Scans your source mesh and automatically detects its bone influence limits. Detects 4-bone limits (GTA V / FiveM / UE safe), 8-bone limits (Cinematic / Film), or rigid 1-bone armor. Setting Max Influences to
AUTO enforces the exact source standard on your clothes with zero export spikes. ⚡ 4 Accelerated Transfer Engines
Switch between Surface BVHTree (barycentric coordinates), KDTree Nearest (C-accelerated high-poly speed), Normal Raycast (floating clothes/coats), and Topology 1:1 (index match).
🎛️ Layer Matching & Mix Modes
Filter transfer by All Groups (By Name), Active Group Only, or Selected Pose Bones. Blend weights seamlessly using Replace, Max (Keep Higher), and a fine-tunable Mix Factor slider (0.0 to 1.0).
👁️ Real-Time Viewport GPU Rays (Blender 4.2 to 5.1+)
Displays glowing cyan connection rays and contact points directly in the 3D Viewport without forcing you into Weight Paint mode. Compatible with Vulkan, Metal, and OpenGL.
🌐 7-Language Instant Switcher (i18n)
Switch immediately between English, Español, 简体中文, 日本語, 한국어, Deutsch, and Français in 1 click right in the N-Panel header. All dynamic tooltips and description cards update in real time.
