Most Iray HDRI environments set don't allow depth of field use easily and DIRECTLY out of the box.

UltraHD IRAY HDRI With DOF - Concrete Boardwalk does!

You won't have to tweak anything, all the presets are there for you to just click and render.

What you'll get is 1 ULTRA HD (up to 16K) custom made Environment, with or without Depth of Field presets.

This environment is a country road, perfect for "ready to render" and "fast to render" scenes...

This environment is provided in 4 different resolutions, based on your needs and computer capabilities:

• 16000 x 8000
• 8000 x 4000
• 4000 x 2000

• Each resolution is provided with or without Depth of field capability.

You can also use the DOF enabled environment and NOT activate the DOF of the camera for a 3rd and different effect.
