Regarding component generation capabilities, the integrated PartGen has been upgraded to version 1.5. Its core segmentation accuracy has been improved from $1024^3$ resolution to $1536^3$, allowing more complete retention of model details. Notably, the new version introduces an innovative "brush interaction" feature, enabling users to perform fine-grained control over model components with a brush, making complex 3D segmentation tasks more aligned with professional design requirements. This also provides more reusable components for 3D printing.

At the same time, the underlying base model has been upgraded to Hunyuan 3D 3.1 version. Building on the improvement in geometric detail, the new version has deeply optimized the accuracy of texture color reproduction, effectively solving the interference of lighting environments on material colors. In addition, to meet the advanced needs of professional designers, Hunyuan 3D Studio now supports input from single image/four views to "eight views", introducing new reference image injection technology for top, bottom, and 45-degree left and right angles, significantly breaking through the previous modeling perspective limitations.
