Text-guided 3D face synthesis has achieved remarkable results by leveraging
text-to-image (T2I) diffusion models. However, most existing works focus solely
on the direct generation, ignoring the editing, restricting them from
synthesizing customized 3D faces through iterative adjustments. In this paper,
we propose a unified text-guided framework from face generation to editing. In
the generation stage, we propose a geometry-texture decoupled generation to
mitigate the loss of geometric details caused by coupling. Besides, decoupling
enables us to utilize the generated geometry as a condition for texture
generation, yielding highly geometry-texture aligned results. We further employ
a fine-tuned texture diffusion model to enhance texture quality in both RGB and
YUV space. In the editing stage, we first employ a pre-trained diffusion model
to update facial geometry or texture based on the texts. To enable sequential
editing, we introduce a UV domain consistency preservation regularization,
preventing unintentional changes to irrelevant facial attributes. Besides, we
propose a self-guided consistency weight strategy to improve editing efficacy
while preserving consistency. Through comprehensive experiments, we showcase
our method's superiority in face synthesis. Project page:
