Method
Extracts a surface from a procedural by first voxelising it (but only voxelising the spatial areas which are required) and then constructing a smoothened surface over the voxels. The surface produced is a triangle mesh which can be texture and deformed, can cast shadows, and can be used as a particle emitter among other things.

Transform
| Name |
Description |
| Position X |
Move its position along the x-axis in local space. |
| Position Y |
Move its position along the y-axis in local space. |
| Position Z |
Move its position along the z-axis in local space. |
| Rotation Heading |
Rotate the object about the x-axis. |
| Rotation Pitch |
Rotate the object about the y-axis. |
| Rotation Bank |
Rotate the object about the z-axis. |
| Scale X |
Scale along the x-axis. |
| Scale Y |
Scale along the y-axis. |
| Scale Z |
Scale along the z-axis. |
Inherit Transform Channels
Toggle which transform channels should be inherited. By default, all are on.
Attributes
| Name |
Description |
| Grid Width |
Width of the adaptive voxel grid. |
| Grid Height |
Height of the adaptive voxel grid. |
| Grid Depth |
Depth of the adaptive voxel grid. |
| Error Tolerance |
If the procedural distance field has too much distortion then it may be necessary to raise the error tolerance. A higher error tolerance may reduce performance, so this is a trade-off. |
| Smoothing Iterations |
The number of vertex smoothening iterations to perform. This will smoothen out sharp edges. |
| HQ Smoothing |
When enabled, vertex positions will be projected back on to the procedural surface. This preserves sharp edges without increasing the voxel grid size. |
| Distance Field Normals |
Vertex normals will be extracted from the procedural distance field. This can be more accurate, but slower. |
| Seal Boundaries |
When a procedural intersects the bounding box, usually a hole is created. Enabling this option will fill in the hole. |
| Generate Colours |
Uses colours set in procedural nodes (such as 3D Primitive) to colourise the generated vertices. This can reduce performance slightly. |
| Generate UVs |
Generate texture coordinates at the generated vertices, for use with a material. This can reduce performance slightly. |
| Visible |
Control whether the node is visible or not to the scene. |
| Dynamic |
When set above 1.0, the mesh will be re-generated on every frame. When set to 0.0, the last-generated mesh will be cached and re-used as a static output. |
| Vertex Buffer Size (100,000s) |
Limits the generated vertex buffer size. |
| Triangle Buffer Size (100,000s) |
Limits the generated triangle buffer size. |
| Show Metrics |
Displays information about the amount of mesh geometry being generated. |
| Tessellation Enabled |
Enables GPU-side tessellation. Note that post-tessellated geometry is processed last. |
| Max Tessellation Factor |
The maximum level of GPU tessellation. |

Inputs
| Name |
Description |
Typical Node Input |
| Procedural Root |
Use a Procedural Root as an input, so the renderer is treated seperately from the roots transforms. In this case, the renderer itself would be connected to the scene Root node. |
Procedural Root |
| Bounding Box |
The region in which the surface will be voxelised and generated |
Bounding Box |
| Render Transform |
Takes the transformation of another node and applies it to the rendered mesh. |
|
| Material |
A material to apply to the rendered mesh |
Materials |
| Transform Modifier |
Links all transform properties to the input node. |
Null |
| Target Node |
Always faces the x-axis towards the inputs anchor point. |
Null |
| Local Transform Override |
Override the transformation values of the node, relative to its parent. |
Null |
Outputs
There are no outputs from this node.
