Model File Import

Import Settings Description

model_inspector_import

  • Scale: The global scale of the scene.

  • Improve Cache Locality: Reorders triangles for better vertex cache locality.

    This feature tries to improve the ACMR (average post-transform vertex cache miss ratio) for all meshes. The implementation runs in O(n) time.

Note

This optimization may decrease actual rendering performance. It is recommended to profile the application before and after using this optimization to ensure it is beneficial.

  • Find Same Meshes: Finds identical mesh instances and joins them into one.

Note

This post-process can take a while because it compares all meshes with each other by vertices.

  • Join Meshes: Joins meshes with the same materials and vertex layout.

    If a mesh has skinning, this process will be skipped.

  • Join Identical Vertices: Merges identical vertices to reduce vertex count.

  • Remove Redundant Materials: Searches for redundant or unreferenced materials and removes them.

  • Pre Transform Vertices: Applies node transformations to vertices. It can also merge meshes with the same materials into one mesh.

  • Optimize Scene Tree: Collapses and joins nodes without animations, bones, lights, or cameras assigned.

  • Flip UVs: Flips all UV coordinates along the y-axis and adjusts material settings and bitangents accordingly.

  • Flip Winding Order: Adjusts the output face winding order to be clockwise (CW). The default face winding order is counterclockwise (CCW).

  • Generate Normals: Imports normals from the model file or generates them.

    • ImportNormals: Uses normals from the model.

    • Hard Normals: Ignores normals present in the model and generates new ones.

    • SmoothNormals: Ignores normals present in the model and generates and smooths new ones.

  • Import Meshes: Enables or disables importing meshes from the model file.

  • Import Materials: Enables or disables importing materials from the model file.
