Adequate UV island padding — at least 4 px at 1K, 8 px at 2K. Prevents bleeding at low mip levels.

Re-bake with edge padding — Blender's Bake settings include 'Margin' (set to 16+ px for safety).

Use AI Texturing in Meshy — projects textures with awareness of seam locations to minimize visibility.

For procedural shaders — use tri-planar mapping which doesn't rely on UVs and eliminates seams entirely (great for organic materials like rock, dirt).

Match texel density across islands — uneven density makes seam transitions sharp. UV editor's Display Stretch shows this.

For PBR — ensure normal map seams are 'aligned' (tangent space consistent across islands).

For hero close-ups, add a hand-painted touch-up pass in Substance Painter or Photoshop on the seam regions.

Structural edits + animation, in Meshy + Blender:

Generate or import the base mesh in Meshy.
Use Remesh (optional) to get clean quad topology, which makes deformation smoother during animation.
Export BLEND or FBX.
In Blender: structural edits in Edit Mode (move vertices, add edge loops with Ctrl+R, sculpt with Sculpt brushes). For non-destructive edits, use modifiers (Subdivision Surface, Lattice, Shrinkwrap).
For rigging: Add → Armature, position bones, parent the mesh with automatic weights. Or use Mixamo's auto-rigger by uploading the FBX, downloading the rigged version, importing back to Blender.
Animate via the Action Editor — keyframe the bones, build a walk / talk / idle cycle. Or import Mixamo motion clips for ready-made animations.
Export FBX or GLB with animation tracks baked.

For characters specifically, Meshy's Animate skips steps 5–6 — it auto-rigs and applies preset motions in under 30 seconds. Use it for fast results; use Blender when you need custom motion or hero polish.

Retopo workflow ranked by speed:

Inside Meshy — use Remesh on the asset. Rebuilds clean quad topology with edge loops at joints, re-unwraps UVs, with controllable target polycount. Handles most cases without leaving the browser.
For specialist character work needing precise loop control — export OBJ to Blender. Use the RetopoFlow add-on for snapping new geometry to the high-poly source. Manual but precise.
Maya — Quad Draw tool. Industry standard for hero retopo.
ZBrush — ZRemesher with curves directing edge flow; combined with Multires for sculpting refinement.
After retopo, transfer textures — bake the original textures from the high-poly source onto the new low-poly UVs in Blender (Cycles → Bake → Diffuse, Normal). Or run AI Texturing in Meshy on the retopologized mesh.
Validate — auto-rig with Meshy Animate or Mixamo to confirm topology is animation-ready.

The right tool depends on whether you need 'good enough' (Meshy Remesh) or 'studio-grade' (Blender + manual retopo).

Proportional accuracy means the 3D model matches the input image's silhouette, dimensions, and feature placement. Critical features:

Multi-view support — single-image generation infers unseen sides; enabling Multi-view with front/side/back views captures actual proportions. This is the most impactful setting.
Silhouette fidelity to input — generate, then overlay the model's projected silhouette over your input image; they should match closely.
Predictable scale relationships — the generator shouldn't randomly resize features.
Pose preservation — the input pose should survive the generation.
High-resolution input — at least 1040×1040 px gives more accurate proportions than low-res.
AI Texturing with reference — keeps surface treatment matching the input.

Test method: generate the same character with and without Multi-view from the same source; compare proportions. Multi-view will win on accuracy. For maximum proportional accuracy, provide front + side + back + three-
