Goal

A bulk upload flow: pick many files (or a folder) at once, review them in one list, and upload them as a batch -- with LOD and physics meshes found automatically.

Auto-detection of companion meshes

Physics meshes, by name, both as separate files and as objects inside the same file:
- suffixes/prefixes such as _phys, _physics, _PHYS, _col, _collision, and the common UCX_ / UBX_ / UCP_ prefixes;
- matched to their visual mesh by base name (e.g. chair.dae + chair_phys.dae, or object Chair + Chair_phys in one file).
LOD meshes, by name: _LOD0.._LOD3, _high / _med / _low / _lowest (and the same as separate files).
Show what was matched per model (visual / LODs / physics) with a way to override any match; unmatched models fall back to the current defaults (generated LODs, chosen physics shape).
Support the formats the uploader accepts today (COLLADA .dae; glTF/GLB where supported).

Batch review

One list of all models with per-model settings (scale, physics shape type, LOD generation, include textures, rigging/weights) plus "apply to all / to selected".
Per-model and total estimated land impact and total upload cost (L$), fetched the same way the single uploader gets its fee quote, shown before anything is spent.
Validation per model before upload (missing physics, degenerate geometry, too many materials, over size limits) with clear errors.

Upload

Uploads run one after another (or a small, server-friendly number at a time) through the existing mesh upload capability; progress per model; the batch can be paused/cancelled between models.
Explicit confirmation of the total L$ cost before starting; each upload is charged separately by the grid, so a partial batch must report exactly which models were uploaded and charged.
Inventory safety: no blind retries of a request that may have been charged/created; a failed model is reported and can be retried deliberately; results land in one destination folder.

Out of scope / later

Auto-generating physics meshes (convex decomposition) when none is provided -- the existing physics options stay.
Bulk texture upload (separate).

Today the mesh uploader (LL's model preview floater) handles one model per upload, with LOD and physics meshes picked by hand per model. Builders with many models (a furniture set, a modular building kit) repeat the same steps dozens of times. ## Goal A bulk upload flow: pick many files (or a folder) at once, review them in one list, and upload them as a batch -- with LOD and physics meshes found automatically. ## Auto-detection of companion meshes - **Physics meshes**, by name, both as separate files and as objects inside the same file: - suffixes/prefixes such as `_phys`, `_physics`, `_PHYS`, `_col`, `_collision`, and the common `UCX_` / `UBX_` / `UCP_` prefixes; - matched to their visual mesh by base name (e.g. `chair.dae` + `chair_phys.dae`, or object `Chair` + `Chair_phys` in one file). - **LOD meshes**, by name: `_LOD0`..`_LOD3`, `_high` / `_med` / `_low` / `_lowest` (and the same as separate files). - Show what was matched per model (visual / LODs / physics) with a way to override any match; unmatched models fall back to the current defaults (generated LODs, chosen physics shape). - Support the formats the uploader accepts today (COLLADA .dae; glTF/GLB where supported). ## Batch review - One list of all models with per-model settings (scale, physics shape type, LOD generation, include textures, rigging/weights) plus "apply to all / to selected". - Per-model and **total** estimated land impact and **total upload cost (L$)**, fetched the same way the single uploader gets its fee quote, shown before anything is spent. - Validation per model before upload (missing physics, degenerate geometry, too many materials, over size limits) with clear errors. ## Upload - Uploads run one after another (or a small, server-friendly number at a time) through the existing mesh upload capability; progress per model; the batch can be paused/cancelled between models. - **Explicit confirmation of the total L$ cost** before starting; each upload is charged separately by the grid, so a partial batch must report exactly which models were uploaded and charged. - Inventory safety: no blind retries of a request that may have been charged/created; a failed model is reported and can be retried deliberately; results land in one destination folder. ## Out of scope / later - Auto-generating physics meshes (convex decomposition) when none is provided -- the existing physics options stay. - Bulk texture upload (separate).
