Recorder - Cant output linear unclamped?!?

[newguy123]

Hi guys

Seems there’s no way of outputting unclamped linear data from Unity. Or, there’s also a strong possibility I’m just doing something wrong!

I posted this originally on the HDRP section based on my findings with GameView, but then I tested it by atually outputting to EXR from targetted cam, and the result is a clamped linear image

Game View clamped to 8bit color - So Tonemapping not visually correct for HD unclamped output

Hi Guys Since the GameView appears to be clamped to 8bit color, any tonemapping mapping like ACES or Custom curve does not seem to have the full range uf unclamped info available to properly tonemap the image. This becomes claringly apparant, when either switching to Neutral, Aces or adjusting a custom curve. The resulting image in Gameview is dull and clearly not correct. Is there a way I can correctly see the correct output? If I for example use Recorder and output unclamped EXR image from …

That’s clamped!

Hey @newguy123 ,

Looking at your other thread, the Recorder settings are good (Target Camera, Linear EXR) but there a couple of other settings in the project that could prevent getting unclamped values.

On you rendering camera you’ll want to:

• Disable the “dithering” option (when this option is enabled, it applies an 8-bit dithering over the image that clamps values)
• “Post Anti-aliasing” is not set to FXAA (other types of anti-aliasing are fine but FXAA clamps values at the moment)

The following HDRP post-processes also clamp values and need to be disabled:

• Tonemapping
• Film Grain

Let us know if you still can’t get unclamped values in your recordings after this. Cheers!

Ah brilliant thanks @cguertin I had dithering enabled on my cam. After disabling that, it sorted it, thanks!
