FBX SDK 2016.0 by default writes FBX files with new format, incompatible with previous SDK version. There is a note about it in a readme:
Updated file format to 7.5 (compatible with 2016+ products) which now uses 64bit integers in the binary block headers to allow for large file support (>2GB). These new FBX files will NOT import in older products (2015 or less), so make sure you set the right export format if you need to target these older products.
But I can't find a way to "set the right export format" in my code to export into previous format.
Tried this in my export setup code with no luck:
fbx_manager_->GetIOSettings()->SetIntProp(
EXP_FBX_EXPORT_FILE_VERSION, FBX_FILE_VERSION_7400 );
What is a correct way to request saving with older format version?
