How can I convert this textures to flame-textures?

This is an excellent work! I want to use this textures on flame!
But，the head model have 20481 vertices, it is not compatible with flame!
How can I convert this textures to flame-textures?

Hi @gongfc , did you find out how to do this ?
FYI, In https://github.com/csbhr/FFHQ-UV/blob/main/FLAME_Apply_HIFI3D_UV/flame2hifi3d_assets/FLAME_w_HIFI3D_UV.obj , the UV coordinates of the HiFi3D++ UV-texture map corresponding to the Flame vertices/faces are provided (https://github.com/csbhr/FFHQ-UV/blob/main/README_flame2hifi3d.md), using these UV coordinates, the FLAME meshes can look for texture colors from the UV-maps in HiFi3D++ format.
I need to basically copy the pixels from one UV texture into the corresponding location in the new UV texture. Any tips on how to get this correspondence?

Thanks a lot !!
Best
