OneClick Asset Pre-Check is a lightweight Blender add-on that helps you quickly identify common asset issues without exporting anything.

It provides a fast PASS / WARN overview and optional safe fixes, making it ideal as a last check before export or asset delivery.

What it does:

• Runs validation on selected objects, the active collection, or the entire scene

• Optional filters to require mesh objects and skip hidden objects

Checks performed:

• Object is not a mesh

• Scale is not applied (scale ≠ 1,1,1)

• Object has no materials

• Mesh has no UV maps

• Ngons (faces with more than 4 vertices)

• High polygon count (over 200,000 faces)

• Duplicate object names within the checked scope

Informational hints (not warnings):

• Object names starting with UCX_ / UBX_ / USP_ / UCP_ (collision-style naming)

• Object names containing “LOD”

Report & results:

• Generates a readable report inside Blender

• Stores the last report and status for review

• Result status is PASS or WARN

• Report can be saved to a Blender Text Block, copied to clipboard, or cleared

Safe fixes (Fix Selected):

• Sanitize Names – trims whitespace, replaces spaces with underscores, and removes duplicate underscores

• Apply Scale – applies object scale (sets scale to 1,1,1)

• Origin to Geometry – sets the object origin to its geometry (bounds-based center)

Fixes do not modify mesh topology, but they may change transforms or origin placement.
