Polycam to Unity cleanup

Clean up a Polycam scan before importing it into Unity

Prepare a Polycam, phone photogrammetry, LiDAR, GLB, OBJ, PLY, or ZIP scan package for Unity by checking scale, pivot, orientation, mesh noise, texture weight, material links, file size, and GLB or FBX handoff notes before engine import.

Best Answer

A Polycam scan can be useful for Unity prototypes, but it is rarely Unity-ready by default. Treat it as a captured asset package: upload the exported GLB, OBJ, PLY, or ZIP, preview scale and pivot, inspect noisy geometry, holes, texture size, material references, polygon count, and file weight, then optimize or convert only after the scan passes a Unity import checklist.

Who needs this Polycam-to-Unity cleanup page

  • Unity developers importing Polycam, phone photogrammetry, LiDAR, or scan-derived GLB, OBJ, PLY, ZIP, and texture folders into a prototype scene.
  • Technical artists deciding whether a captured prop, room, statue, collectible, or environment piece is light enough for Unity WebGL, mobile, or playable prototype use.
  • Teams comparing scan workflows with Meshy, Tripo, Hunyuan, Luma-style capture, marketplace, or handmade assets while keeping upload_click, file_type, engine_target, export_format, and failed_upload_reason measurable.

Unity import risks to catch before opening the project

Scale and pivot drift

Scans can arrive with real-world units, odd origins, tilted orientation, or a bounding box that does not fit the target Unity scene.

Noisy geometry and holes

Photogrammetry surfaces may include floor fragments, wall edges, holes, spikes, or dense triangles that need cleanup before collision or gameplay use.

Heavy texture packages

Scan exports often include large texture maps or texture folders that inflate build size and slow Unity WebGL or mobile loading.

Material and format mismatch

OBJ, PLY, GLB, and ZIP handoffs may preserve different material details, so inspect the actual package before choosing GLB, FBX, or OBJ.

Editor-first Polycam to Unity workflow

  • Upload the exported scan package and record file_type, source_tool=unknown, and failed_upload_reason when the package is unsupported, too large, corrupt, or missing textures.
  • Preview the scan outside Unity first: inspect scale, pivot, orientation, bounding box, texture links, material slots, polygon count, texture size, file size, and visible capture artifacts.
  • Optimize only what helps the target Unity scene: reduce triangles, compress textures, crop noisy capture fragments, normalize scale, and keep before/after notes.
  • Convert after inspection, then export Unity handoff notes for GLB, FBX, or OBJ and record engine_target=unity and export_format so the cleanup funnel is measurable.
  • Use Unity, Blender, MeshLab, or coding-agent scripts after the asset review when deeper mesh surgery, import automation, or scene placement is required.

CTA and measurement plan

  • Primary CTA uses upload_click because Polycam visitors usually already have a scan export and need a cleanup gate before Unity import.
  • Use source_tool=unknown until analytics has a dedicated scan-source taxonomy; segment by file_type=glb_obj_ply_zip and engine_target=unity instead.
  • Track editor_open, editor_action, optimize_click, convert_click, export_click, edit_to_export, sample_asset_use, signup, paid_conversion, and failed_upload_reason to compare scan cleanup with AI-generated model cleanup.

FAQ

Does SEELE integrate directly with Polycam or Unity?

No. This page does not claim a direct integration with Polycam, Unity, or Unity Asset Store. It covers an editor-first cleanup workflow after a user has an exported scan package.

Can I import a Polycam scan directly into Unity?

Sometimes for rough visual prototypes, but most scans should be checked for scale, pivot, noisy geometry, texture weight, material references, file size, and target-platform limits first.

Should I use GLB, FBX, OBJ, or PLY for Unity?

Choose after inspecting the actual package. GLB can be convenient for compact preview, FBX may fit some Unity pipelines, OBJ is common for mesh handoff, and PLY or point-cloud data may need extra conversion.

What does the CTA track?

The page should track upload_click, file_type, source_tool=unknown, failed_upload_reason, engine_target=unity, export_format, sample_asset_use, optimize_click, convert_click, export_click, edit_to_export, signup, and paid_conversion.
