Hi Fabrizio,

You can set the sun in your Environment Slot and Enable your Visible Environment Pin and plug your desired HDRI into that. Just make sure to enable your Backplate in Visible Environment so you can see the HDRI.

Hope this helps,

Hi Ryan,
and thanks for the tip.
I'm just wondering if it is possible to use hdri as sky light in conjunction with the sun light.

Yes, set the Environment->Daylight Environment->Sky Texture to the HDRI map.

Thank you, Paul.
I tried it and works fine!
Anyway, I haven't much control over the power of the sky (hdri) because the power value (in the Environment) controls sky and sun light. I would like to increase the light of the sky and decrease the light of the sun.

True. You can increase the brightness of the sky texture by decreasing the texture Gamma.
