Syntax

int32 OriginalDataSectionIndex

Remarks

This represent the original section index in the imported data. The original data is chunk per material, we use this index to store user section modification. The user cannot change a BONE chunked section data, since the BONE chunk can be per-platform. Do not use this value to index the Sections array, only the user section data should be index by this value.
