There aren't really that many, unless I misunderstand. + +--- + +_**Assistant**_ + +You're absolutely right! Looking at the screenshot, it shows "Found: 1663" linked assets, which seems way too high for a typical Blender scene. This suggests there's an issue with how we're counting linked assets. + +The problem is likely in our scanning logic - we're probably counting the same asset multiple times or including things that aren't actually user-linked assets. Let me fix the scanning operator to be more accurate: + + +--- + +
