Sims 4:0x034AEECB

Format from Maxis Documentation

This information was provided on Sept 5, 2014 by SimGuruModSquad on [official forums] as part of the Modding Documentation.

The layout will be using the Maxis provided data type descriptors, i.e.: UINT32 vs DWORD

This is what was discovered early in the process -- now obsolete

 DWORD version	// 0x1a is current
 DWORD offset	// to resource reference table from end of header (ie offset + 8)

 DWORD presetCount? // For all files I read so far, it's 0. It might still be a count
 7STRING		// UnicodeBE
 FLOAT sortPriority	// CAS sorts on this value, from largest to smallest

 // This block hasn't been test for multiple files.
