Sculptura

What Sculptura is

Sculptura 2 is a 3D sculpting app for creatives who want to work on an iPad with Apple Pencil. Its engine uses volumes based on signed distance fields rather than traditional polygon meshes. Artist-curated presets provide starting tools, while the Tool Factory lets users create their own. Models can have separate layers with different volume resolutions, and users can paint materials with vector strokes. Physically based rendering and image-based lighting show models in real-world lighting environments. The app offers interactive path-traced rendering and ray-marched rendering for high-resolution models, with sculpting and rendering accelerated by Metal. Path-traced rendering requires an iPad with an M1 chip or later, which the maker also recommends. Sculptura automatically generates UV maps for exporting models to paint in Procreate, and supports OBJ, STL, and USDZ import and export. The listed Sculptura 2 plan is $14.99 a month, though the plan details say it is a one-time purchase with no subscription. The app is available for iOS; the maker says no macOS version is currently available and Android is not planned.
