Volume strange result Redshift

You can not manipulate the Emission gradient that way. There must always be a black chit on the far left 0.0 position of the gradient. That effectively masks out all that temperature noise. Lock that position down, then place a companion color chit next to it to achieve your look.

Yep, but here is a screenshot, the first is the problematic scene, I've changed the shader with the one I use with the second screenshot and I have again a bad result ?

As the temperature value are not in the 0-1 range, you need to tweak the old min and old max value of the emission Remap Range in the advanced tab of the rsVolume.

By the way I've worked in sRGB as I'm not comfortable with OCIO
