Remesh

Produce a new triangle count from an existing mesh - a Detailer or a Sculptor result - without regenerating the texture. Fast. A Detailer pass is not a prerequisite: you can remesh a Sculptor output directly.

The quick way to simplify a mesh

To lighten a model you already have, remesh it rather than re-running the Detailer at a lower decimation_target. Remesh reuses the existing geometry and texture, so it's much faster and cheaper - and you keep the same model, just lighter, instead of generating a new one.

Re-decimate a mesh

POST /api/v1/detailer/remesh

Requires API key.

Two modes:

Whole-mesh (default) — leave focus_on_node_names empty and the new decimation_target is spread across every part of the model.
Part-focused — pass one or more part names in focus_on_node_names and the budget is applied only to those parts. Every other part keeps its current resolution, so you can lighten (or refine) a single component without touching the rest.

Whole-mesh remesh works directly on a Sculptor output - you do not need to run the Detailer first. Part-focused remesh is the only exception: it needs per-part data, so it is only supported on part-preserving Detailer results (created with preserve_parts: true). A merged or Sculptor-based parent has no per-part data and returns 400 for part-focused mode.

Request Body

Name	Type	Description
`parent_submission_id`	string (required)	ID of a completed Detailer or Sculptor submission. Whole-mesh remesh accepts either; part-focused remesh requires a part-preserving Detailer.
`decimation_target`	integer	Target triangle count. 1,000–200,000. Default: `200000`. Whole-mesh when `focus_on_node_names` is empty; otherwise the budget applied to each focused part.
`remesh`	boolean	Run quad remeshing before decimation. Default: `true`.
`focus_on_node_names`	string[]	Restrict the new budget to these named parts. Empty = whole mesh. Part-preserving detailer parents only.
`project_id`	string	Assign to a project.
