The Mesh Volume SDF node will import a 3D model in .obj format and convert it to a Signed Distance Field, SDF volume. The node can be found under the Geometry category in the Nodegraph Editor window. By default, the Mesh Volume SDF node has a Diffuse material attached to it (figure 1). This can be changed to any other material type under the Material 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).
