GRS Studio v1.92
Take an evolutionary leap in garment and hard-surface retopology. Build your mesh in 2D, evaluate in real-time 3D with Live Preview and dynamic Thickness, then project and stitch it onto your model with flawless mathematical precision.

Work in 2D while instantly evaluating the result in 3D. The engine projects your flat mesh onto the Highpoly model in real-time, automatically syncing materials to check edge flow and texture stretching. Now featuring O(1) optimization for zero FPS drops even on extremely dense meshes!
Enable non-destructive thickness dynamically in Live Mode. Adjust volume and offset to see how the garment fits without visual clutter, and bake it into real modifiers upon snapping.
Retain ultimate control over complex geometry. The add-on generates pattern boundaries as N-Gons, allowing you to use the Knife tool to slice them into logical blocks and direct your main edge loops.
The engine natively recognizes and routes topology around internal cutouts, pockets, and buttonholes.
Select 4 corners of any prepared block and hit "Fill Grid". The procedural engine instantly fills the segment with a perfect quad-grid, featuring parametric smoothing and internal edge distribution.
Any manual tweaks instantly snap back to the guide curves. The smart normalization algorithm equalizes edge lengths across homologous seams, guaranteeing 100% stitchability.
Project your 2D mesh back onto the Highpoly target with absolute precision. It doesn't just stick to the surface—it bakes exact 1-to-1 UV coordinates and mathematically forces 3D seam edges into identical coordinates.
Say goodbye to pulled UVs and deleted polygons. A surgical point-merge algorithm safely welds even complex T-junctions, preserving multiple loops to create physically correct, distortion-free UV seams.
A killer feature for GameDev. Mark inner layers of folded hems and collars with "Ignore Stitch". They will snap perfectly to the model but won't be welded, completely preventing "non-manifold" geometry.
Select your High-poly mesh. UVRetopo analyzes existing seams, extracts them onto a 2D plane as editable curves, and automatically places structural corner points (Endpoints) for your future patches.
Fill the perimeters with N-Gons and direct your main loops with the Knife tool. Then, simply select the 4 corners of any segment, and the procedural Coons Patch engine will fill it with mathematically perfect topology.
Use Clamp Mode to slide vertices along curves like rails. With a single click, sync your manual edits and normalize edge spacing across all seams so they match perfectly in 3D.
Send the mesh back to 3D! The engine wraps it perfectly around the high-poly surface, generates flawless 2D UV islands, and surgically welds the specified edges while safely ignoring hidden multi-layer details.
