Hi,
yes, refer to the same 3d-model file (depth, stl or obj) in each pano,
and use different depthmap.origin setting for setting the individual origin/center/camera position for each scene:
https://krpano.com/docu/xml/#depthmap.origin
When the 3d-model is already loaded, it will be automatically reused without new loading or parsing.
Best regards,
Klaus
