Ported from BBS You can now right-click a part and choose Subdivide Part to apply Loop subdivision with multiple iterations. This is useful for models with low original mesh resolution. > [!NOTE] > 1. Only meshes without non-manifold edges are supported. > 2. Color attributes will be lost after subdivision. We recommend subdividing first, then painting and applying colors. Not perfect and it can break some features but a nice to have and we can improve it. https://github.com/user-attachments/assets/33f10e49-f6dc-44d3-8c21-9e12e1fe23dc Best case scenario a sphere: Each picture is a Mesh subdivision step over the other <img width="541" height="495" alt="260202_164257_orca-slicer" src="https://github.com/user-attachments/assets/e62b3f4d-ee6b-4451-95a4-40a154d3a405" /> <img width="541" height="495" alt="260202_164302_%pn" src="https://github.com/user-attachments/assets/f7399457-be8d-45e7-b93f-f42064dadd64" /> <img width="541" height="495" alt="260202_164306_%pn" src="https://github.com/user-attachments/assets/55370035-219f-4b7f-94f4-9b31733820d6" /> <img width="541" height="495" alt="260202_164310_%pn" src="https://github.com/user-attachments/assets/3be8c904-cc6f-4efe-b4f8-f390b50d310c" />
