Syntax
TArray< FMeshBatch > Materials
Remarks
Materials for each segment, in the form of mesh batches. We will check whether every segment of the geometry has been assigned a material. Unlike the raster path, mesh batches assigned here are considered transient and will be discarded immediately upon we finished gathering for the current scene proxy.
