I know that the gamma 1.0 has been explained before, but if a new build for VRay next is in the pipeline, is there any way to work with gamma 2.2.
I raise this point as I have had numerous issues with importing purchased models that use normal mapping as well as other 3rd party plugins/scripts - Realpeople Resizer script to name but one.
Thanks.
That said, any version of SR for Vray next would be greatly appreciated.

Hello !
Not sure to understand clearly your needs... if you want we can discuss deeper about the buttons into the Preview panel of solidRocks. Maybe it can help (srgb and post buttons)
About Vray next, Please have a look on the Project status section in this moment, there's good news !

Hi. Thanks for your email. Unfortunately the project status section is locked - it has been locked for a long time. Even when logged in it doesn’t work. I’d love to see what’s in there!!

Regarding the gamma, as far as I can see, SR changes the image output gamma from 2.2 to 1.0.

For some reason, this has caused issues with 3rd party plugins that write out an image then re-uses it ( like the example I gave). It also doesn’t handle 3rd party models who have textures with gamma set to 1.0 (normal maps).- I have to go through each texture and change it.

A long time ago you explained to someone why SR worked with 1.0 but I can’t remember why. I was just wondering if everything could default to gamma 2.2 for input and output?

Hello ! Oh really ? i need to check that !! i'll solve the restrained access to project status issue asap

Did you tried the "post" button into the mini preview panel of SR ? maybe it can help you ? It does not applies gamma 2.2 ;)

Yes, this might be down to user error.
I use sRGB and 'Post' switched on. It's the only way I can find to save images with the correct gamma for my system (2.2).

You can see this issue in the VFB History. Any images saved to the VFB History that weren't rendered using SR, automatically go darker when SR is launched - this might only apply to my settings above?

I know SR does alter the image I/O gamma setting on launch, so I was just wondering if the gamma could be left untouched and we have Gamma 2.2 throughout as a default? Is Gamma 1.0 needed anymore seeing as the industry has moved to 2.2?
Thanks

Would you please try this ?
Into SR preview panel, you can uncheck srgb button. After taht, SR will let you manage your gamma manually.
You'll need to save these settings to SR via the init/save panel to make this change permanent for you new scenes.
Does it helps ?
