Arcane SDF

✨ Version 1.2.0Blender 4.2 LTS • 4.5 LTS • 5.x+⚡ Real-Time GPU Raymarcher📦 Zero Required Dependencies

"Sculpt with Math. Blend with Freedom. Model Without Topology Limits."

Arcane SDF brings non-destructive, real-time Signed Distance Field (SDF) modeling directly into Blender's 3D viewport. Create complex hard-surface concepts, smooth organic silhouettes, and intricate mechanical panel cuts without fighting edge loops, non-manifold geometry, or boolean pinching.

🚀Why Model with Signed Distance Fields?

Traditional polygonal boolean modeling requires constant topology clean-up, remeshing artifacts, and fragile vertex welding. SDF modeling changes the rules:

• Artifact-Free Smooth Booleans: Adjust smooth blending radii in real time with mathematically perfect curvature.
• Topology-Free Blockout: Focus 100% on shape, silhouette, and proportion without fighting mesh density.
• Native Blender Workflow: Manipulate shapes with standard Blender gizmos, hotkeys (G / R / S), and Empty controllers.
• 100% Watertight Output: Convert directly to clean manifold polygon meshes or export OpenVDB volume grids for simulation and rendering.
