I recently encountered and resolved an issue after the 36.10v update, and I’d like to share the solution in case it helps others.
After the update, I started seeing the following error log:
/{MyProjectName}/Maps/{MyProjectName} Errors logged while validating asset
Root Scene Component was not a Primitive component type, could not calculate overlaps for actor Actor_UAID_6C02E0519CA4F96702_1736387240.
Root Scene Component was not a Primitive component type, could not calculate overlaps for actor FortPlaysetRoot_UAID_6C02E0519CA4F96702_1737382609.
Through investigation, I found that this error occurs when a LEGO asset is placed as a child of a Root Scene Component that is not a PrimitiveComponent. This prevents overlap calculation from working properly.
To resolve this, I made sure that LEGO assets are not attached under a non-primitive Root Scene Component, and that fixed the issue.
Hope this helps others facing the same problem!
