Cinema4D version 2022.1.1-R6 (Obsolete stable) 08.07.2023

[Kalua]

New build (R4) is out with some fixes! Enjoy it!

Thanks a lot!
Looks great!
Is there a demo scene to learn how to set the Field Shape Texture node? Have been trying it out but with no results.

I understand technically why you say Aces doesn't do this and shouldn't.

But as artists wanting speed and primarily caring about what the visual image looks like, this is important. I don't want to look at my image in liveviewer and then be like "I think this will look good if I take it into photoshop or aftereffects or an alternative app to do more color correction". Aces I find is giving me a nice look, however I think its very important as an artist to then have the ability to break the rules and have further ability to force tonemapping and change highlight compression and gamma. It may not be 'technically' the right thing to be doing but visually it looks good. So I believe we want to have this feature or otherwise another color correction set of tools that can be done during the liveviewer process to do this. So we aren't jumping around between programs.

Lastly, I posted a video a few comments back using aces and had this ability in the 2021 plugin. Potentially it may have been setup wrong but from what I can tell from using it for the past year, It was setup correctly and was allowing me to do this feature.

Thankyou for your responses though SSmolak and Arronwestwood

On your last point re your video, you can still turn on force tonemapping in the current version (2022). But doing so, this is no longer ACES and will produce incorrect color interpretation. You also double dip and turn on ACES in the camera which switches to Octanes implementation of ACES, this isnt needed if you are using the OCIO from the IPR drop down menu. You can pick 1 or the other but don't need to do both.

Without knowing how much you know, but OCIO is a color management tool. Its not a LUT or a filter and is made to be exact and consistent which is why you have limited control. Its not a 'rule breaking' type workflow, its purpose is accuracy.

With what you are wanting, I think you would get far more mileage finding a LUT set you like which gives more 'creative' options in the IPR which allows for full camera imager functionality. As mentioned the devs do want to implement more post processing and post color correction workflow tools for compositing down the track, but until then I think your best bet is LUTS.

Hello there! Any chance to solve this issue? If i have object with transparency inside of a VDB volume i can clearly see the mesh boundaries.

Thank you for Shape Fields ! It is very powerfull for creating dirts around chosen objects. But I found two issues :

1. It doesn't work correctly for sdf from objects ( space translation issue )

sdf_1.jpg

It works fine for regular sdf's

sdf_2.jpg

2. Using SDF's in scene cause crash while restart rendering.

3. Field Shape doesn't work while connecting Projection node to it.

Scene attached.

Hi, SSmolak
Would you mind sharing the setup on how to make this "Field shape node" to work? Have been trying to make it work with no success.

Hi, scene attached. You need to drag SDF object to Shape Input in Field Texture also link it in Transform Node too to match position.

If you use restart render in Octane LV - it will crash.

Thank you!
I will take a look and share my experience!

As wrote in release notes, shape field is not stabilized yet. Crash are expected. Also there are unoptimized structure on my side. You need to wait for stabilization.

It works pretty good as for first implementation. I think that would be great if shape create more wider texture. At the moment it distance is very small even on max setting.

I'm noticing when I change over to Aces Tone mapping.

It would be reducting to qualify ACES solely as a "tonemapping" (tool or whatever). It isn't.

I'm unable to change gamma values?

As it should. Typical Transfer functions are handled through the ACES OCIO config-file (IDTs, ODTs).

Also if want to render out my aces tone mapped version just a straight 16bit Png. No AOVs or anything. What do I need to set in the render setting to get the same look as the live viewer?

JPG over PNG and then simply the ACES sRGB ODT, assuming everything else has been set correctly. PV should have its own "color profile" disabled (named as such, IIRC).

ACES disable gamma and highlight compensation.

OCIO does*

To art direct my specific look. (...) Aoktar - Please re-enable this feature as Aces has a great look but is very limiting with the use of highlight and gamma abilities

That's an ACES limitation. Octane is one of the few to support OCIO Looks, which allows OCIO-level customization but does require some familiarization with OCIO itself. A similar thread.

As mentioned the devs want to implement more CC/PP tools, but these will sit ontop of the OCIO just like in any other compositing/grading app.

Spot on. I've been mentioning it in the past, one of the best additions is ASC-CDL which works in conjunction with any OCIO config-file and is also industry-standardized from digital cinema cameras to post-workflows.

As far as OCIO’s go, I like using either blender filmic or AGX as I prefer the outputs, and provides ’more’ contrast control. Or you can find a lut that gives a mimic effect to ACES and still use that in conjunction with the base imager, not ideal but the option is there. Either way, bunch of options to play with

AgX more than "Blender Filmic" as this one falls into the deprecated category.

I'm also finding it difficult to get out my aces rec709

I'm assuming sRGB (ODT) was implied, not the Rec.709 one (slightly different purpose).

I know its not 'Accurately' the right way of working. But for artists like myself. Its about speed and efficiency and have the liveviewer being the final image a lot of the time.

Unfortunately, it's a fallacious thinking. The "digital imaging world" is chaotic enough that such thinking doesn't have its place. Evidently, nobody will arrest you for doing it wrong but it shouldn't be normalized, especially for working around in-renderer limitations (there are none in-post).

ACES profile

This has absolutely no meaning. Let's avoid screwing up the defined and usable terminology.

In the custom AOV node editor, when adding a new node it seems to mess up the current placement of nodes, i was using comment boxes, so maybe something to do with that? - cheers!
