Hi,

I am on Paraview 6.0.1 and when I load a HDRI and enable it as Environment with OSPRay, the scene is very dark and the background HDRI is also very dark.

Here’s a free HDRI that I used:

> **[Free HDRI Map 812 HDRI SKIES](https://hdri-skies.com/free-hdris/hdri-map-812/)**
>
> Free hdri sky map for CGI visualizations, VR, AR, Virtual Productions, VFX and media.

And this is what it looks like in Paraview with OPSRay on:

When I use PBR with the Skybox instead, the background image looks better, although it is still a bit too dark.

Dark is not the best word because the colours are shifted, noon is actually turned into a sunset.

I confirm the behavior, that OSPRay rendering with HDRI is darker that it should be. Please open an issue.
