Render sequence not recognizing color management

Anonymous
Not applicable

I am having a problem with getting render sequence to recognize my color management settings.  If I save the image directly from the render view then the color management settings work fine.  However, as soon as I save a series of images via render sequence it seems to ignore the color management settings.

Hi!

 

View Settings are only for the actual View(er Window) and not for rendering (burn in)

Check Render Settings and set Output Transform or Gamma Correction there.

I have "Apply output transform to renderer" checked in the color management preferences, but that doesn't seem to do anything.

I am having the exact same problem.

 

Based on this tutorial: https://www.youtube.com/watch?v=uUmq8q23wJ8

 

a 16 bit image should hold the information needed, so when you bring it into Photoshop it will correct it (even if you don't see the correction in fcheck). That is not working for me though.

 

If you check "Apply Output Transform to Renderer" it should force the color correction. This is to be used for 8bit images. That does not work for me either.

 

What I am doing now is disabling color management altogether. This will cause Maya to act like 2015 and previous versions where you had to enable it manually if you wanted it.  Go to your preferences > Color Management > and uncheck the box. I'll try to compensate with lighting just to get the darn piece done.

 

I had this problem last week with a toon shader I was using. It was driving me crazy and then when I restarted Maya, color management suddenly worked. I am suspicious it is a defect in the software. If I had more time on my project, I'd look for a service pack update, but there is no way I'm going down that rabbit hole right now.

Basically, as I can see it, Maya will only provide color correction in the preview, not in the batch renders. Trying to force it with "Apply Output Transform to Renderer" doesn't work. It is better to apply color correction in the next step of your workflow, for example in Photoshop or After Effects.

 

In After Effects, you can go to Effect > Color Correction > Gamma/Pedestal/Gain. Increase the Gain for each RGB channel to 2.2. This should match sRGB setting.

 

In Photoshop you can use Image > Adjustments> Exposure. Increase the gain to 2.2.

 

 

That is the best I can figure out.

Hi!

 

What renderer are you using?

 

Color management is not supported with the Maya Software, Maya Hardware, or Maya Vector renderers.

I'm using Arnold 4 I believe. 

 

The only solution I can come up with so far is just to manually save each frame from the render window.

Hi!

 

"The only solution I can come up with so far is just to manually save each frame from the render window."

Please don't do this, sounds horrible.

 

Use the Gamma Attribute as shown in the link i provided for Arnold 4!

The gamma attribute really doesn't fix the problem.

Hi!

 

What does this mean "The gamma attribute really doesn't fix the problem."  ?

Is the value ignored? It should work.

 

I don't have Arnold 4 anymore so i can't test it.

 

Please render 2 images with different Gamma settings and upload the result.

As you can see by this image, turning down the gamma doesn't do anything for the white areas that are blown out.

Hi!

 

"turning down the gamma doesn't do anything for the white areas that are blown out."

Of course not.

 

My advice: Install Arnold 5 and Use View Transform (it should be the best option for you),

or learn more about Color Management and Color Spaces.

Hi!

 

Looking at your image i wanted to add:

 

If you use any of the image tools in render view like Exposure or Gamma (slider) (they are not part of Color Management like "sRGB gamma"), these are just for preview and can not be set to be part of the render process. If you want to change exposure you have to adjust the lighting in your scene, or change exposure setting of the camera.

 

If you want to simulate "sRGB Gamma" in Arnold 4, set Gamma in Render Settings to "2.2",

 

but again , i suggest to use Arnold 5, as this is better integrated in the Color Management Process and has some huge shader improvements.
