SketchUp to Unity Problems: Missing Textures, Wrong Scale, Broken Faces

Most SketchUp to Unity problems are not about getting a file into the editor once. They show up after import, when the model looks wrong, scales badly, or loses material fidelity.

Wrong Scale Usually Starts at Import Settings

Unity's SketchUp import settings include unit conversion, and the official importer docs call that out explicitly. If the first import comes in too large or too small, fix that before you build prefabs, lighting, or collisions on top of the asset.

Materials and Textures Need an Early Review

Unity can read materials from SketchUp, but not every SketchUp feature survives the trip. The importer docs also list unsupported elements, which is why a messy architectural file often looks incomplete when it lands in-engine.

Broken Faces Often Mean Backface Trouble

Thin surfaces and reversed faces are common in SketchUp-originated models. If the asset starts disappearing from certain camera angles, inspect face orientation before blaming Unity.

A Safer Recovery Path

• Re-import after checking unit conversion.
• Audit reversed faces and paper-thin geometry in the source.
• Move to FBX if you need a more conventional engine handoff.
• Use GLB when runtime preview and reuse matter more than editor-native import.
