I made a 360º panorama in a folio (DPS). It is made with Pano2VR exported as HTML 5. Placed in InDesign with the web overlay panel and It works great.
Now I trying to do the same in EPUB3. I can not get it to work.
Can you insert your own HTML files (not OEM) in Indesign?
or are there other ways to get panoramas into EPUB3?
Folio overlays are not supported in EPUB. The only way to pass HTML content to EPUB is via HTML object in InDesign. Goto Object->Insert HTML. In the dialog that opens up, paste the HTML code you want to embed and press OK.
These HTML objects are only supported in EPUB as of now.
