Mesh Volume SDF


The Mesh Volume SDF node will import a 3D model in .obj format and convert it to a Signed Distance Field, SDF volume. By default, the Mesh Volume SDF node has a DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters. material attached to it (figure 1). This can be changed to any other material type under the MaterialThe representation of the surface or volume properties of an object. rollout on the node. The node rebuilds a Signed Distance Field based on the Voxel Size and Border Thickness parameters available in the Import Settings (figure 2).

The resolution or voxel size of the volume can be adjusted using the Edit Settings button (figure 2).
