Hi,
I'm not sure about my color space workflow.
Normaly, I choose a camera preset, leave the gamma to 1.
But some rendere becomes bright.
What are your color space workflow?
Continu to say that support of the native lw color space thing, if possible, would be a must have.
Thanks.

Octane has it's own color space and tone mapping functions, so the best workflow is use the Octane settings and leave all the LightWave color space settings disabled. In the imager node you have all the options related to image output (gamma, tone map, etc.), and in the texture node you have the gamma parameters to correct the input textures.
If you enable the LW color space settings, it is easy mix the octane tone mapping with the LW color space settings, overcorrecting the image. And anyway, the native Octane output files (render passes and so on) can't use the LightWave color space settings.
In short: Disable the LW color space functions, and work with the Octane gamma and tone mapping parameters.

Thanks Juanjgon,
Ok, but I don't undersdtand something. When I choose a camera profile, is it gamma corrected? Do I need to change the gamma or leave at 1?
What I like with the lightwave color space is that you don't need to do all the colors, images, ecc... corrections. This is auomaticaly done.
With other solution, like the tonemapping in octane or other software, you need to enter the correction for every textures and calculate all colors correction.
And somtimes, this is a pain.
Thank you again for your help.

Yes, as far i know the camera profiles include all the tone mapping corrections, including the gamma, so you should leave the gamma parameter to 1.0
Usually all 8 bit texture files should be 2.2 gamma corrected. Only for the HDR linear images you should set this value to 1.0 in the texture node.
