SMLoader.PostProcess

Calculates the tangents and bitangents for the imported meshes.

Identifies and joins identical vertex data sets within all imported meshes.

Converts all the imported data to a left-handed coordinate space.

Triangulates all faces of all meshes.

Removes some parts of the data structure (animations, materials, Generates normals for all faces of all meshes. light sources, cameras, textures, vertex components).

Generates smooth normals for all vertices in the mesh.

Splits large meshes into smaller sub-meshes.

<hr>Removes the node graph and pre-transforms all vertices with the local transformation matrices of their nodes.

Limits the number of bones simultaneously affecting a single vertex to a maximum value.

Validates the imported scene data structure.

Reorders triangles for better vertex cache locality.

Searches for redundant/unreferenced materials and removes them.

This step tries to determine which meshes have normal vectors that are facing inwards and inverts them.

This step splits meshes with more than one primitive type in homogeneous sub-meshes.

This step searches all meshes for degenerate primitives and converts them to proper lines or points.

This step searches all meshes for invalid data, such as zeroed normal vectors or invalid UV coords and removes/fixes them. This is intended to get rid of some common exporter errors.

This step converts non-UV mappings (such as spherical or cylindrical mapping) to proper texture coordinate channels.

This step applies per-texture UV transformations and bakes them into stand-alone vtexture coordinate channels.

This step searches for duplicate meshes and replaces them with references to the first mesh.

A postprocessing step to reduce the number of meshes.

A postprocessing step to optimize the scene hierarchy.

This step flips all UV coordinates along the y-axis and adjusts material settings and bitangents accordingly.

This step adjusts the output face winding order to be CW.

This step splits meshes with many bones into sub-meshes so that each su-bmesh has fewer or as many bones as a given limit.

This step removes bones losslessly or according to some threshold.
