What you think about ACES / ACEScg


Recommended Posts

Hello Artists

 

ACES here ACES there..... 

 

Not every Software and Renderer supports ACES and ACEScg yet but I think it will change the Rendering, colorgrading and post workflow.

This is a great side to see and learn what colorgrading and ACES is.

What are your experience with ACES and ACEScg? Do you start using it? What you think about?

Hello!

 

ACES starts to change the way we grade the projects' color. And now we can notice it in different movies. Some software and rendering engines start to support it as you mentioned, and I will mention some of them (After effects, Davinci Resolve, Arnold, Redshift, etc.)

 

I have been using this color system for a year now, and I will never go back to the old color grading.

 

Hope all the software support ACES, so everyone can experience it.

Provide tools and tutorials. Follow Up!

From what I have understood, ACES are most valuable when you have different Cameras angles in the scene and basically what ACES do is midigate light differences, especially if you have different types if Cameras, so you save a tons of time on top of making reflections and lights look more natural and simply better.

It is the future standard for sure.

 

Have you converted your textures to ACES? Since C4D cannot do it it is not really ACES.

 

ACES in C4D and Adobe is a horror pipeline at the moment since both do not care to support. Maya and Nuke you are fine. As always.

 

The whole ACES thing is an overcomplicated mess at the moment but it is because many apps not yet support it. And because of that it would be important that MAXON and Adobe implement it properly because then it would work its way into mainstream graphics world out of the VFX/Hardcore Tech area.

I agree with Zenden. I think ACES and OCIO are the professional future.   I hope MAXON take a really serious look at their whole colour management workflow to be honest. 

 

Even basic linear workflow is a bit of a mess. I work with Redshift. Every other DCC and pro renderer is based on a fully linear workflow. I know the node materials are linear based, but there are so many problems using them with something like Redshift, I have to stay with the Xpresso based shader graph - and sRGB / linear workflow.

Yes, Igor, you are right! But also the Idea of ACES is to support everything that generates imagery: cameras, Software, etc. and maybe we will see that on every display, who knows!

Yes! I have converted all the textures to ACES with Arnold. You are right C4D still not supporting ACES, but After Effects does, you only need to download the OpenColorIO plugin.

ACES is a new inbetween standard. ACES is just the System. Try to not mix things together. There is ACES the System and ACEScg or ACEScc and ACEScct. Inside that System. What for 3D Artists is important to know in the system ACES is ACEScg. ACES cg is very similar to Rec709. In Cinema 4D and Redshift you can use OCIO and a Node that converts the sRGB Diffuse texture to the ACEScg colorspace. Its more an work arround but it works. Now starts the System. So you export an open EXR rendered out with OCIO profile and inport it into your comp software. Now the input is ACEScg and that goes into ACES the System where the colorgrading happen. After that goes to Rec709 or what ever Outputformat you need.

The trouble is - it's a partial and cobbled together system at the moment - and will remain so until MAXON fully embrace it.

For example: lets say you want to pipe in a solid colour picked from the C4D picker into diffuse. Once that goes through ACES conversion it won't be the same colour. Therefore very difficult to pick the right colour in the first place...
