Remesh

Regenerate a model's mesh topology, optimizing face count and arrangement so AI-generated meshes become production-ready.


TL;DR

  • Regenerates a model's mesh topology, optimizing face count and face arrangement.

  • You can specify a target polygon count to balance quality and performance.

  • AI-generated models typically have excessive triangles and irregular topology — Remesh makes them production-ready.

  • Required before 3D printing to ensure a watertight (hole-free, closed) mesh.


When to Use

  • The model's face count is too high and needs to be reduced (games: under 50K, mobile: under 10K).

  • The model needs to be 3D printed — watertight mesh is mandatory.

  • You need cleaner topology for downstream operations (UV unwrapping, animation rigging, etc.).


When NOT to Use

  • The model already has acceptable face count and good topology.

  • You're in the concept exploration phase — Remesh only the final asset.


Step-by-Step

  1. Select the target model.

  2. Enter the Remesh tool.

  3. Set the Target Polygon Count (e.g., 10K faces).

  4. Click Remesh and wait for processing.

  5. Compare the original and remeshed model: check detail preservation.

  6. If satisfied, replace or save as a new model.

FAQ

What does Remesh do in Meshy?
Remesh regenerates a model's topology, optimizing face count and arrangement so AI-generated meshes become production-ready.
How many polygons should a game model have?
Aim for under ~50K faces for PC games and under ~10K for mobile; set your target polygon count in the Remesh tool.
Do I need to Remesh before 3D printing?
Yes. Remesh can produce a watertight (hole-free, closed) mesh, which is mandatory for successful 3D printing.
Will Remesh reduce my model's detail?
Lower targets trade some detail for performance; compare the original and remeshed versions and raise the target if needed.
When should I Remesh in my workflow?
Remesh the final asset before UV unwrapping, texturing, or rigging — skip it during concept exploration.

  • AI Texturing — Retexturing after Remesh produces better results

  • Unwrap UV — UV needs to be regenerated after Remesh

  • Rigging — Clean topology is essential for rigging
