splitMesh
| Name | Description |
|---|---|
| splitMesh(node, policy, createChildNodes, removeOldMesh) | Split mesh into sub-meshes by VertexElementMaterial. Each sub-mesh will use only one material. Perform mesh splitting on a node |

| removeOldMesh | boolean | Remove the old mesh after split, if this parameter is false, the old and new meshes will co-exists. |
Result: VertexElementUV
splitMesh
| Name | Description |
|---|---|
| splitMesh(scene, policy, removeOldMesh) | Split mesh into sub-meshes by VertexElementMaterial. Each sub-mesh will use only one material. Perform mesh splitting on all nodes of the scene. |

| removeOldMes | boolean | null |
Result: VertexElementUV
splitMesh
| Name | Description |
|---|---|
| splitMesh(mesh, policy) | Split mesh into sub-meshes by VertexElementMaterial. Each sub-mesh will use only one material. The original mesh will not get changed. |
Result: Mesh[]
buildTangentBinormal
| Name | Description |
|---|---|
| buildTangentBinormal(scene) | This will create tangent and binormal on all meshes of the scene Normal is required, if normal is not existing on the mesh, it will also create the normal data from position. UV is also required, the mesh will be ignored if no UV is defined. |
Result: Mesh[]
buildTangentBinormal
| Name | Description |
|---|---|
| buildTangentBinormal(mesh) | This will create tangent and binormal on the mesh Normal is required, if normal is not existing on the mesh, it will also create the normal data from position. UV is also required, an exception will be raised if no UV found. |
Result: Mesh[]
