Hi Dr. Sassi,

If it is okay with you, could I see a screencapture of you UV unwrapping a symmetrical character head? I was amazed at how you have this symmetrical UV of this character’s head in this post: https://www.cineversity.com/forums/viewthread/4700/

I tried doing it with UV relax and assigning different points as “pins”, but I can’t get that symmetrical look correctly
Thank you so much

Hi openmindedcomedy,

If you have just the initial unwrapping in mind (not the symmetry painting:

Please note that the frontal project is vertical aligned (edges and Y-axis); the viewing angle will determine the result! Hence why I show it a few times.

I was unsure if you needed the symmetry paint, as you pointed to the thread with that specific question, or how to align a mesh.

Here are two screen captures.

Besides that, I would highly recommend going through Thanassis’ series about UV.
https://www.cineversity.com/vidplaytut/hard_surface_modeling_uv_unwrapping_introduction
and
https://www.cineversity.com/vidplaytut/hard_surface_model_uv_unwrapping_-_introduction_ui_scene_overview

Yes, they are not directly for organic shapes, but the certainty you gain with those might be worth the time.

Does this answer your question? If not, please provide a scene file (Dropbox, Amazon, Adobe, Apple, Google, Wetransfer, please do not shorten the URL, thanks. I can also provide an upload link.)

Enjoy your weekend

The first screen capture answered my question. Thank you so much! I guess that workflow just automatically symmetrize UV. This is the exact workflow that I do, probably I just forget that it symmetrize automatically because my instinct instantly goes to fixing the UV distortions. Do you have a way to fix distortions while maintaining the symmetry of the UV? (Either by using some sort of command/commands or like a tool like UV Magnet Tool)

I think I’ve already watched that course like a few months ago (I think that’s where I learned the Project > Relax workflow). I’ll try to re-watch it again some other time

Thank you!

Thanks for the feedback, openmindedcomedy.

There is a Magnet Tool:
https://help.maxon.net/c4d/s24/en-us/Default.htm#html/11715.html#PLUGIN_CMD_17040

However:
The key is to get the Frontal Project as good as possible from the start. If you need that precision, use a camera set to the exact center of the mesh, then pull it back to frame the object (I guess pulling the z-axis should be the right one in most cases).
(Set UVW from Projection is sometimes worth a try, before “relaxing”.)

Since I try to find always new ways, let me share this one with you:

Go into the UV layout and use the PoseMorph slider.
(Works as well with Magnet-Tool created poses.) grin

All the best
