Further discussion about this here, and why it is needed: viewtopic.php?f=9&t=79783&p=421776#p421776

To sum it up, objects that require displacement on only particular parts of the object is not currently supported well - requires UV maps and image masks right now, which is a lot of work when other texture projection types would suffice. The ability to use vertex maps as masks for displacement would be very beneficial, and is something that is currently supported in Redshift. Using subdivision surfaces and doing all of the displacement in c4d so that you can use a vertex map instead of relying on Octane's subdivisions and doing displacement in the material has considerable negatives (harder management and having to manage multiple things instead of doing it in one place, lack of interoperability between Octane nodes and materials and features with the c4d system, extreme scene degredation and performance penalities when using lots of subdivisions, as well having the SDS constantly recalculating when moving around the scene or playing animation keyframes, etc).

Read the thread for further info. But that's the general idea.

Yes, I applied for that just now too.

In any other software it is possible. In order to test and see if it's possible, I did it in Redshift and it works, I saw that it's possible in Blender with Cycles and even in Modo too.

This is a very powerful option that is sorely needed.

I hope it will be possible to do this soon in Cinema 4D's Octane

Hi!
Is there any update about this?

No update on Octane side, but it will not be much different than using C4D's displacement effector. Eventually this is vertex based displacement.

Main problem is that vertex displacement mixer doesn't work with vertex maps :
Strange that Disp Mixer works fine with Field Texture but not in Shape mode :

The best is to use image mask with adaptive subdivision creating by this mask :
But painting doesn't work correctly if image is used somewhere in Octane material.

The displacer effector doesn't work if you want very small details, I normally use texture displacement for that, and I don't get the same result applying a displacer effector, also it increases a lot the polygons on scene.

Octane presents some problems with vertex maps that already has been solved by other render engines. I love octane but I'm already changing to other engine renders for some specific projects.

I know it's a challenge to update the render with all the particles, smoke, and other new features of C4d but I wish it will be so octane users could test it same way.

Thanks anyway.
