Title: Can we have both the previous HDRI and sun in the new HDRI image?
Post by: fa2020 on January 02, 2017, 08:02:39 AM
Hi guys,
When I try to edit HDRI for adding a physical sun, I lose the previous HDRI and just the sun and simple sky is added. How can I keep the previous HDRI and just add the sun to it?
the reason I want to add the sun is that the sun existed in HDRI produces blurry shadow of the objects.

I think that's coming soon .... see https://www.youtube.com/watch?v=aXUrmGO1188 it doesn't show specifically HDRi + SunSky combo but you never know it might sneak its way in!

Photoshop open and writes HDR files. So you can create both HDR's and blend them In Photoshop together.
If you create a sun and sky HDRI, you can save this as a HDZ file. Now create a new scene in KeyShot with a frame ratio of 2:1  (e.g. 1000x500 Pixel). There's no need for an object to render. Then change environment setting to backplate and choose your new Sun&Sky HDZ file.
And now you can render a 32-bit TIFF or PSD file in the resolution you need, to use this in Photoshop.

Check the attached files. The HDR is very bright!

Hope that helps

Cheers
Marco
