Free Studio HDRi Spherical Sky image

Post by Fletch » Sat Jun 20, 2020 9:30 am

Here is a scene with a deceptively simple Studio HDRi we have developed.
Please test for yourself with your objects of choice, and post here so we can see your results.

Any feedback is welcome. :hat:

The skull in the attached file was provided in high-poly format on

Unzip the hdri from the attached .zip file.
Open your Twilight Render Environment settings - and load the .hdr file into the sky channel.
When you load this .hdr spherical image into your future scenes, keep in mind that you will need to rotate the image to match your camera view. ;)

EDIT: Please delete this post - since I could not post the image of the problem, I opened a new thread under Technical Support [V2]

Well, thought I would spend some time understanding how this all works. I downloaded both the HDRI file and the skull model and did some playing around. Then I decided I would take another model I have and see what I could do with it. Think I learned some things but then wound up with some questions:
  1. How can I open your HDRI file so I can look at it and understand what it looks like?
  2. What is the best way/tool to create my own HDRI files?
  3. I used both the Exploration Render facility and the Normal Render tool and see huge differences in the result (see the image below). Why is there such a difference? How should/when is the best time to use the Exploration capability?
EDIT: I did not get the option to add my image to the post.
