I am not totally sure about VR but you can get 360 spherical panoramic images with any renderer plugin i believe.
Just set a spherical camera and make the resolution 2:1 proportioned. Also creating ‘two-point perspective’ renders might be useful depending on your scene.
Ricoh Theta has a free ‘Spherical Viewer’ for desktop: https://theta360.com/en/support/download/pcmac/
Also you can upload and share your spherical panoramas via this website: http://sky.easypano.com/
