Remarks
Updates a section of this procedural mesh component. This is faster than CreateMeshSection, but does not let you change topology. Collision info is also updated.
Parameters
| Name | Description |
|---|---|
| Vertices | Vertex buffer of all vertex positions to use for this mesh section. |
| Normals | Optional array of normal vectors for each vertex. If supplied, must be same length as Vertices array. |
| UV0 | Optional array of texture co-ordinates for each vertex. If supplied, must be same length as Vertices array. |
| VertexColors | Optional array of colors for each vertex. If supplied, must be same length as Vertices array. |
| Tangents | Optional array of tangent vector for each vertex. If supplied, must be same length as Vertices array. |
| bSRGBConversion | Whether to do sRGB conversion when converting FLinearColor to FColor |
