PlaneMesh

public PlaneMesh();

Creates a 2×2 XZ rectangle with normal +Y, centered at (0, 0, 0). Without subdivisions it has 4 vertices and 2 triangles. It has zero thickness; a wall, physics shape or closed volume needs the corresponding additional setup.

public Vector3 CenterOffset { get; set; }

Local offset applied to every vertex, default (0, 0, 0). Changes geometry and its Aabb within the resource, not MeshInstance3D Position. A shared resource applies the change to every instance.

public PlaneMesh.OrientationEnum Orientation { get; set; }

Positive normal axis: X, Y or Z; defaults to Y. Y creates an XZ plane, X a YZ plane and Z an XY plane. Changes resource geometry, not instance Transform. Supply a valid enum value; back-side visibility and double-sided rendering depend on orientation and material.

public Vector2 Size { get; set; }

Two full rectangle dimensions, default (2, 2). With Orientation Y, size X maps to local X and size Y to local Z; with X they map to Z and Y; with Z to X and Y. These are resource-local axes, not the Entity world rotation. Use finite positive dimensions. Changes update geometry and the lightmap hint when AddUV2 is enabled.

public int SubdivideDepth { get; set; }

Additional cuts along the second Size.Y direction, default 0. Negative input is stored as 0. This is not necessarily local Z: with Orientation X or Z the second direction is Y. Segment count is value + 1.

public int SubdivideWidth { get; set; }

Additional cuts along the first Size.X direction, default 0. Negative input is stored as 0. Segment count is value + 1; the corresponding local XYZ axis depends on Orientation. Regenerates geometry without changing dimensions.

public Vector3 GetCenterOffset();

Returns CenterOffset. Local offset applied to every vertex, default (0, 0, 0). Changes geometry and its Aabb within the resource, not MeshInstance3D Position. A shared resource applies the change to every instance.

public PlaneMesh.OrientationEnum GetOrientation();

Returns Orientation. Positive normal axis: X, Y or Z; defaults to Y. Y creates an XZ plane, X a YZ plane and Z an XY plane. Changes resource geometry, not instance Transform. Supply a valid enum value; back-side visibility and double-sided rendering depend on orientation and material.

public Vector2 GetSize();

Returns Size. Two full rectangle dimensions, default (2, 2). With Orientation Y, size X maps to local X and size Y to local Z; with X they map to Z and Y; with Z to X and Y. These are resource-local axes, not the Entity world rotation. Use finite positive dimensions. Changes update geometry and the lightmap hint when AddUV2 is enabled.

public int GetSubdivideDepth();

Returns SubdivideDepth. Additional cuts along the second Size.Y direction, default 0. Negative input is stored as 0. This is not necessarily local Z: with Orientation X or Z the second direction is Y. Segment count is value + 1.

public int GetSubdivideWidth();

Returns SubdivideWidth. Additional cuts along the first Size.X direction, default 0. Negative input is stored as 0. Segment count is value + 1; the corresponding local XYZ axis depends on Orientation. Regenerates geometry without changing dimensions.

public void SetCenterOffset(Vector3 offset);

Sets CenterOffset. Local offset applied to every vertex, default (0, 0, 0). Changes geometry and its Aabb within the resource, not MeshInstance3D Position. A shared resource applies the change to every instance.

public void SetOrientation(PlaneMesh.OrientationEnum orientation);

Sets Orientation. Positive normal axis: X, Y or Z; defaults to Y. Y creates an XZ plane, X a YZ plane and Z an XY plane. Changes resource geometry, not instance Transform. Supply a valid enum value; back-side visibility and double-sided rendering depend on orientation and material.

public void SetSize(Vector2 size);

Sets Size. Two full rectangle dimensions, default (2, 2). With Orientation Y, size X maps to local X and size Y to local Z; with X they map to Z and Y; with Z to X and Y. These are resource-local axes, not the Entity world rotation. Use finite positive dimensions. Changes update geometry and the lightmap hint when AddUV2 is enabled.

public void SetSubdivideDepth(int subdivide);

Sets SubdivideDepth. Additional cuts along the second Size.Y direction, default 0. Negative input is stored as 0. This is not necessarily local Z: with Orientation X or Z the second direction is Y. Segment count is value + 1.

public void SetSubdivideWidth(int subdivide);

Sets SubdivideWidth. Additional cuts along the first Size.X direction, default 0. Negative input is stored as 0. Segment count is value + 1; the corresponding local XYZ axis depends on Orientation. Regenerates geometry without changing dimensions.
