Thank you.
Yeah, I was kind of afraid it might be something like a dynamic shader... Since I don't know Blender, I cannot "reverse engineer" the shader setup in Blender.
So, basically, no wrinkles on characters exported to C4D for the time being, i.e. until and unless Reallusion provides an Auto-setup for C4D as they appear to do for Blender or documentation on how to use which blend-shapes to control the which masks (Control how? The opacity of the mask?).

BTW: I guess the same problem applies not only to C4D, but also to Maya, 3D Studio, and any other 3D application except for Blender and the game engines.

In short, here is no mesh deformation. You essentially have to build a dynamic shader where wrinkle texture (9 baked maps) would overlay/blend the original (diffuse/normal/roughness) utilizing various masks based on values of certain blend-shapes.

This is how shader looks in Blender for instance:

Hi Peter,
Thanks for getting back to me on this.
Having to do things manually on the C4D side is something that also applies to the rest of the iClone exports (materials), so that is not unexpected. ;-)
I watched some of the tutorials you linked to but, as far as I can tell, these have more to do with editing wrinkles or their use in iClone.
What I would like to know is how to use the textures exported from iClone in my C4D materials:
a) Do I need the wrinkle textures for the bump channel of my C4D material or for deformation (i.e. are the wrinkles an optical effect (bump) or actual mesh deformation)?
b) Do I need to layer up the various wrinkle and basic textures using the masks for the different facial areas so as to have one "flattened" layer for the bump/deformation channel in the skin material? Does the same apply to roughness (flattening those layers into one using the same masks)?

Hi...

Unfortunately we don't have an Auto Setup tool for C4D as we do for Unreal, Unity and Blender. This means everything has to be done manually on the C4D side. We also don't have any dedicated Wrinkle C4D tutorials for this pipeline as yet, but hopefully we can work on one for the future.

However, you can find lot's of information about how Wrinkles work and transfer in the available documentation and video tutorials.

No information available? Really?

When I exported a character with wrinkles from iClone, I noticed additional textures for the head: 3 each of wrinkle_diffuse, wrinkle_roughness, wrinkle_flow, wrinkle_normal. Is there documentation/a tutorial on what each of these textures do and how they can be used in shaders outside of iClone, in my case Cinema 4D with Redshift?
