I've a large scene with a lot of custom props. When I decide I don't want to use these props I delete them, but upon saving and using the Resource Collector, I can see by the filesize etc that these props are retained.
Is there a way to actually permanently remove unused models? ie Purge unused?
Thank you for posting your question and you seem to be following all the steps necessary to purge elements, there is one thing that could still be present and that would be the texture. Make sure to have unselected unused materials in the resource collector when's saving the file.
Otherwise you can easily check by going to the Multi/Gallery view in the Thumbnail preview when selecting a material with the material picker. Any material without a check mark should be deleted as it is not being used.
If the file size still did not change there could be something else happening and we would need to investigate to better understand the cause. Please contact us directly to report a bug by using the [ contact us ] button from the home page or by following this link:
