Field to Grid Node

The Field to Grid node creates one or more new voxel grids by evaluating geometry fields on the topology of an existing grid. This allows generating new volumetric data (such as density, temperature, velocity, or distance fields) directly from field inputs defined in the node tree.

Each input field is sampled at the voxel positions of the provided topology grid, producing a corresponding output grid that matches the same resolution, transform, and domain. This enables consistent evaluation of multiple attributes or procedural quantities across the same volume structure.

Inputs

Topology

The reference grid whose voxel layout, resolution, and transform define where the input fields will be evaluated.

Additional input sockets can be added for each field to be evaluated. Each field defines a scalar or vector value to sample on the topology grid.

Fields can be added by dragging them into the blank socket area.

Note

When a color field is connected, it will be evaluated as a Vector data type, since color grids are not currently supported.

Properties

In the properties panel, each field input can be configured individually. This includes setting its data type (such as Float, Vector, or Boolean) and managing the order of evaluation. Each field input produces a corresponding output grid.

Outputs

For each field input, a separate grid output is created that contains the evaluated voxel data. All output grids share the same topology as the input grid, ensuring that they are aligned and compatible for further processing or combination.
