Converting a UV texture made for HiFi3D++ into a UV texture for FLAME

[Oocean35]

Hi @csbhr,
Thanks a lot for sharing this amazing work ?
Any idea how to convert a UV texture made for HiFi3D++ into a UV texture for FLAME ?
Thanks a lot !

There are two possible ways to achieve this:

1. Use the interactive nonrigid registration tool to align the HiFi3D++ UVmap to the FLAME topology;
2. Recreate the FLAME topology assets, and redesign the DataSet_Step4_UV_Texture process to generate the FLAME version of FFHQ-UV.

However, converting a HiFi3D++ UV map to a FLAME UV map is not a trivial matter.
We have provided a way to directly apply the HiFi3D++ UVmap on the FLAME head mesh, please refer to [here].

hi, is there some more detailed steps

I think there are still limitations to FLAME heads, but if I had a head model created by Character Creator4, how should I convert this
