Environment HDRIs don't match the Unity viewport

[adamnerva]

When adding an HDRI texture to the environment in the PBR render target, the HDRI texture doesn't match the Unity viewport. It seems to be a colorspace or gamma issue. The environment texture is just way too dark in the Octane render.

Hi adamnerva,
you need to set the Gamma at 1 for HDRI in Environment node.

Thanks, beppe,

OK, that fixes it. Can we consider this a bug? Why would the environment texture slot be defaulting to gamma 2.2? It would be good if at least there was an option to fix this in the Unity Inspector pane, as it did not occur to me to check the render target node graph.
