Researchers have identified a critical failure mode in state-of-the-art text-to-3D generative models, termed "sink traps." In these regions, the models become insensitive to prompt modifications, meaning changes in text input do not alter the output geometry. This limitation is not due to the model's geometric expressivity but rather its linguistic sensitivity. The researchers propose a new framework that leverages the model's unconditional generative prior to bypass these sink traps, enabling more robust and high-fidelity semantic manipulation of 3D shapes, particularly for out-of-distribution geometries.
