Attached an example made with the product viewer of a free model downloaded from cgtrader in Rhinoceros format and imported via unreal study.
It’s all very simple and fast.
The only problem I found is that when it is exported to html 5 there are problems with geometry with too many polygons.
Infact when it exceeds a number of polygons the geometry is broken, so you have to export it to different pieces.
This ruins the perfect division of the pieces.
Furthermore, the light has no effect.
This does not happen for the dekstop version.
But I think it’s a known problem since when you open the product viewer the possibility of exporting to html5 is blocked.
