Version 4.3.0

Date: Dec 24, 2025

✨ Features

• High-quality renderer (beta)
  • GPU-based photo-realistic rendering especially enables complex textile materials such as knit, silk, Jacquard, etc
  • Interactive high-quality render can interactively adjust rendering properties in real time and immediately preview the visual results, allowing for faster iteration and more precise visual control
  • AI-powered denoiser delivers significantly faster rendering speeds while maintaining high-quality visual results
  • High-quality render captures up to 4K resolution image and video formats

• Rigid options of patterns and curves #3406
  • Compared to the harden which primarily increases bending resistance, rigid is designed to preserve the original shape more strongly.
  • This makes it especially effective for elements that need to maintain a fixed form, such as bra underwires, bag structures, or corset components, where maintaining the intended silhouette is essential.
  • To use this feature, select the desired pattern or curves and enable it rigid in the Properties panel. Once enabled, users can adjust sliders such as stiffness and density .

• Display the mouse picking point in both the 3D view and the 2D view 

  

• Support more avatar types: infant, toddler, child, girl, and boy
