CLOSED - I figured it out. I missed one item in the submission form which stopped upload. Process is a bit confusing. I realized later the subdirectory was for the install, not the upload., and was able to create pack afterwards.
https://marketplace.reallusion.com/earth-globesphere---animated How do I upload props with Content Uploader? They're not in the list of options. I created a 3D like spinning globe prop that uses 2 popVideos as sprites - One sprite is a still, the 2nd a spinning globe - but I haven't figured out yet how to upload them the the Marketplace.
I'm faced with a few obstacles
1) Props aren't listed in the dropdown box
<Update: I found props under Scene, but still getting error message about sub-types generation>
2) The uploader says I'm missing sub type files, but I can link them in - I added a path to the Subfolder, but that doesn't work.
3) I thought I could group then in the store, but I can't upload to try that - uploader still asks for sub-type files
4) I tried projects, but then I'm back to step 2.

Thanks for any help. I'm guessing the solution is simple, but I'm not figuring it out today.
