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 Node Graph 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).
