Assets that have mature content need to have a visual item on the asset viewing box to mark it as Mature. Adding something like a red box around the box would make it stand out the best or have a icon on the bottom right of the box that labels its rating would work since theirs no info there and its just dead space. Putting the asset type in that corner as well. Example: If its a “.fbx” and/or “.blend” and/or “.mp3” file/files putting that logo or the extension there at on the bottom of the ratting icon. Since the information is already kind of there when you hover over the asset adding this to the bottom corner would make it a better user experience for viewing many assets at once.
Assets that are AI generated need to have a visual indicator on their thumbnail.
