Maine reasons for trying this :
- 69 megapixel resolution !!!!!!!!!… you don’t need Backplates
- 9 frame stops dynamic range (Check the preview video link…)
- [included] The Building 3ds max scene, with Vray setting
- [included] A huge Backplate with more than 44 megapixels
- Background 100% render able
Overall Observations
This huge “360×180 Panosphere HDRI ”, needs 8 frames to get made: 6 horizontals, 1 from the sky and a last one for the ground. Each frame (HDRI) is made from a set of 9 bracketing pictures, starting at stop -4 and ending at stop +4.
Du to the extreme largeness of this Panosphere, the pack includes a single .hdr and no other High Dynamic Range format.
The Quality
With 69 Mega pixels (11748×5874 pix), the background pixels coverage is fine!… You’re free to place your 3D camera anywhere, and render without using black plates.
In fact, this will bring you the necessary freedom for animating your scenes.
HDRI Backplate!
…However, this package contains a Backplate… but a huge one!! …with more than 44 Mega pixels, this backplate would answer to any of your production needs.
Backplate provided in JPG best quality
Backplate size : 9690×4584 pix

8 HDRI were necessary to get this Panosphere.
Etch Basic HDRI Frame was merged from 9 pictures of that frame,
exposed with these values: from -4 to +4 stops, centered at 1/45 sec.
6 HDRI to fill the horizontal line (6frames x 9pictures = 54 pictures)
1 HDRI to fill the sky (9 pictures)
1 HDRI to fill the nadir (ground view)
… But in did, the pano-head and the tripod, both holding the shooting camera,
get included in those nadir set. This is why 3 set of 9 pictures must be made
while the camera’s looking down, producing 3 HDRI .
So 3 HDRI were edited in my picture editor in order to get a Nadir HDR view, cleaned from holding camera materials.
In conclusion, 81 shots, 4288×2848 pix each, were used to get this Panosphere HDRI .
Bonus
The 3ds max scene file, used to create those preview images with a building, is also provided with this package. I hope this is going to help you to set your HDRI scenes with Vray. (3ds max 2009 / Vray 150sp6)
