In our latest 1.5.0 release we added a number of new UVs in FaceBuilder node. Also we added some basic support for custom UVs. Below you can find out how it works.
Our users asked us to change the UV in FaceBuilder because they experienced some difficulties using it in their compositing work, so we decided to add a number of new UVs and keep the old one for compatibility reasons.
First thing first, here’s how to select a UV in FaceBuilder:
And here’s how they all look like:
The most important thing about new UVs is that they use the UV space more efficiently, and the second one, obviously, is that they’re not divided into parts.
Butterfly one is aimed at lowering the distortions not having so many seams as our
Legacy UV has at the same time.
Maxface, on the other hand, gives you as much resolution for the face as possible. And finally, the
Spherical one is actually a slightly adjusted well-known “cylindrical” head UV with better handling of the head top part.
If you’ve been using FaceBuilder and its UVs before, you’d need to recreate the FaceBuilder node in your old scripts in order to use new UVs.
You can also add your own UVs modifying a model in KeenTools installation folder (
data/face_data/mesh103.fbx). Your custom UVs will be shown as
Custom #n in the selection menu. Please keep in mind that FaceBuilder relies on vertices in the model, so if you decide to not only add UVs but to edit geometry as well, keep vertices in the same parts of the face and avoid deleting them.
Here you can download a Nuke example script with UVs showcase.
