Kodon is described as 'aims to provide sculpting experience for beginners, semi-pro and professionals, with a hybrid of surface and volume sculpting - delivering a VR alternative to apps like ZBrush and 3DSMax' and is a Digital Painting Tool in the Photos & Graphics category. There are six alternatives to Kodon for a variety of platforms, including Windows, Oculus Rift, Steam, Oculus Experiences and Self-Hosted solutions. The best alternative is Oculus Medium. It's not free, so if you're looking for a free alternative, you could try A-Painter or Blocks. Other great apps like Kodon are Tilt Brush (Paid, Open Source), MasterpieceVR (Paid) and Quill by Story Studio (Paid).
Medium is an immersive VR experience that lets you sculpt, model, paint, and create tangible objects in a VR environment. You can create expressive works of art with Oculus Touch controllers using authentic hand gestures and movement for a natural, tactile experience.
A-Painter lets you paint in VR in your browser. A WebVR-enabled browser is required. For controls, the experimental Chromium build on Windows supports HTC Vive controllers. You will need to enable Gamepad Extensions in about:config.
Tilt Brush lets you paint in 3D space with virtual reality. Unleash your creativity with three-dimensional brush strokes, stars, light, and even fire. Your room is your canvas. Your palette is your imagination. The possibilities are endless.
MasterpieceVR is the easiest, most natural way to quickly create 3D content. Sculpt and draw using intuitive, dynamic features that let you easily create high quality models for use in games, animation, digital art, VFX, industrial design, 3D printing, etc.
