Hi there,
Maybe someone with some experience in Davinci could help me out here.
I'm just having trouble getting my images to look the same in Davinci as they do in Houdini.

Here's my render in Houdini, I have the view set to 2.2 and the render at Gamma 1

In Davinci it's way darker but here are my colour settings

I'm not trying to match a grade or do anything tricky, I just want to render out some character turnarounds that will eventually be viewed as QT movs.

Any ideas,
Thanks
Pete

I'm using Resolve 12.5…and exrs always are darker like you have when I load them up.

I found I only have to adjust the gamma wheel, bringing it up usually between 0.1 and 0.25.(In Resolve)

I wouldn't try to match gamma 2.2, it looks like shit. Get the aces ocio configs, and you should be able to get them to match.

Hey thanks for the response,
I managed to get pretty close using these settings, it still looks a lot more vibrant in Houdini though.

I haven't tried the ocio configs yet, not sure where to begin with that, which one would you use?
I'm really surprised it's such a challenge to get the same look in Davinci, I would have thought there'd be a way to make it exactly the same.

Thanks,
Pete

can you upload your file please - color-space stuff is full of jargon but it's quite simple.

Yeah - it was my mistake - for perfect colour set the render to ‘linear to sRGB’ in DaVinci. I would use the RMB menu on the clip, not the project, but both work.

The one on the left is your ROP mantra render, and the one on the right is the Davinci 12.5 with default settings;

With the exception that Gamma is brought up to .22

Hey that's awesome, but I'm still doing something wrong

Are there any other places this is set? I tried both approaches but it still looks wrong.

Does this look right? I just made a new project to test it.

dug into it and it's specific MacOS only setting in Davinci in preferences. See the attached project and screengrab for settings.
