remove gamma 2.2 from vfb?

[Stefan-L]

Hi

for some special tonemapping workflow i usually use, i needed to get rid if the gamma 2.2 in the vfb in c4d corona.

in vray this is easy in deactivating the "srgb" button in the vray vfb. is there a way to do similar in the corona frame buffer?

thx for help
Stefan

any news from this?

even a simple gamma setting like the c4d picture viewer has it would help already to remove the unwanted gamma(setting gamma to 0.4545 worst case).

we add custom curves instead of the default lwf, so needed a clean workflow without the baked in gama 2.2 applied.do i oversee anything or is this not yet possible in corona?

in vray this works well and easy... it prevents us to use corona yet in production

Hi Stefan,

in the Corona you could use a LUT with negative range gamma. You could make it in photoshop

Yes, you could. You can also simply bend the curve. ;)

But that's not the point.

For any tonemapper, simple gamma control is an essential part of the tool. Corona's VFB & CIE shouldn't be an exception.
Especially considering its philosophy: "Effortless simplicity."

I rebump this question. Is this something achievable soon?
We need the possibility to  adjust the gamma of a scene as max do it (slider with  scene gamma, to set it up to whatever value needed).
