Method

Combines multiple geometry nodes and freezes them into a single mesh, preserving the materials of the source geometry. The resulting mesh is static: it won’t be regenerated or updated again until the timeline is reset.
Once frozen, the source geometry nodes are disabled from rendering and updating; they will appear hashed out in the nodegraph, with a “frozen” icon on top. Do not hide the source geometry nodes manually or the Freeze Geometry node will be unable to regenerate them.

When the Freeze Geometry node is disabled or it becomes inactive because the time bar is out of range, the source geometry nodes are restored to visibility.

The diffuse/lightmap UV set for the source geometry is laid out onto a grid, with a cell per input geometry node, preserving the uniqueness of these UVs for lightmap baking for use with the Bake Lighting To Object node.

This node is useful for combining several pieces of geometry into one, to optimise complex scenes with lots of nodes.

Rendering

Name Description
Visible Control whether the node is visible or not to the scene.
Seen By Rays Determines whether the geometry is visible to the ray tracer.
Per Object Composite Alpha Overwrites the alpha channel beneath the object, giving simple effect of transparency. Best used when the mesh won’t overlap with other objects, as other meshes will not be seen through the mesh.

Lines

Name Description
Lines Visible Control whether the node is visible or not to the scene.
Lines Alpha Control the alpha value of the lines.
Colour Control the colour value of the lines.
Use Vertex Colours Colour lines based on the vertex colours of the geometry.
Blend Mode Control how the lines blend with the rest of the scene.
Thick Lines Use lines with thickness relative to their distance to the camera.
Hide Back Face Lines Hides the lines around back faces of geometry.
Lock Width Lock the line width to be consistent regardless of distance from the camera. Only functions with Thick Lines enabled.
Thick Line Width Control the thickness of all the lines. Only functions with Thick Lines enabled.
Show Silhouette Lines Draws lines along the edges of the object relative to the camera.
Show Normal Difference Lines Draw a line along the edges of the mesh, depending on the angle difference between their mutual faces.
Show Unshared Lines Draw lines along all edges of the shape.
Show Other Lines Show all the lines for each edge of the Mesh.
Unshared Lines Weight Greater control over the alpha of the unshared lines.
Silhouette Lines Weight Greater control over the alpha of the silhouette lines.
Normal Difference Lines Weight Greater control over the alpha of the normal difference lines.
Other Lines Weight Greater control over the alpha of the other lines.
Line Normal Difference Angle Change the threshold angle between two face normals that will generate a line along their common edge. Only functions with Show Normal Lines enabled.
Line Normal Fade Sharpness How much the drawn normal lines will fade away the closer the edge angle is to the Line Normal Difference Angle.
Line Depth Bias Exaggerate the width of the lines based on the distance to the camera. not functional with Lock Width enabled.
Line Silhouette Fade Sharpness How much the drawn silhouette lines will fade away based on the size of the edge angle to the camera.

Inputs

Name Description Typical Node Input
Geometry Sources Sources of geometry to be combined into a single object. Shape 3D

Outputs

This node outputs the normal transformation and translation values, but it also outputs geometry which can be Deformed or used as a mesh so
