Thanks for the mention, appreciated. Chisel and the upcoming version of Speedsculpt are indeed the most powerful SDF modeling Blender add-ons. Outside of Blender there’s the user-friendly free SDF Modeler.
The Blender devs did shortly mention SDF plans during the BCon 2025, but I haven’t heard anything about that since then. Blender’s Geometry Nodes have some SDF functionality, but it’s live-meshed and therefore slower than ray-marched SDF.
