Validation & errors

Recognize common validation failures before export and fix the source data in Blender.

Validation exists to stop structurally invalid exports before they turn into confusing Unreal-side problems.

Typical checks

• Missing required source data
• Duplicate or ambiguous LOD levels
• Broken collision associations
• Unexpected naming or asset structure
• Invalid placement or instance references

Fix the source

When validation reports an error, correct the Blender source rather than working around the message in the destination project. The source scene should remain the authoritative version of the asset.
