Clayxels is an interactive volumetric toolkit that allows you to sculpt, animate, and procedurally generate game assets or clay-like effects in Unity. It provides real-time meshing and splatted volumetric rendering modes, and can be used in both the editor and in-game. You can freeze your work to a plain standard Unity mesh, and the splatted look persists on frozen meshes. Auto skin weights are generated automatically for any frozen mesh.
With Clayxels, you can create complex architectural shapes in seconds, and export your models to FBX for use in other packages. The toolkit can output meshes, point clouds, or fully shaded volumetric shapes, and can be animated in the editor or used with procedural motion at runtime. Physics work with standard colliders, and you can even use Clayxels to generate its own mesh colliders.
Clayxels is highly customizable, with open C# code, editable render shaders, and signed-distance functions. You can extend or hack the provided APIs, write new shaders, or add your own mathematical functions to change how the signed distance field is generated.
Performance may vary depending on the available GPU, especially when using Clayxels at runtime in your game.
Clayxels is compatible with Unity 2019-2021, and supports Windows and Mac (new gen M chips), all render pipelines (built-in, URP, and HDRP). It does not support mobile, VR, AR, consoles, or WebGL. However, clayxels creations can be frozen to plain standard meshes and deployed anywhere.
