public static AssetBundle LoadFromMemory (byte[] binary, uint crc= 0);


binary Array of bytes with the AssetBundle data.
crc An optional CRC-32 checksum of the uncompressed content. If this is non-zero, then the content will be compared against the checksum before loading it, and give an error if it does not match.


AssetBundle Loaded AssetBundle object or null if failed.


Synchronously create an AssetBundle from a memory region.

Use this method to create an AssetBundle from an array of bytes. This is useful when you have downloaded the data with encryption and need to create the AssetBundle from the unencrypted bytes.

Compared to LoadFromMemoryAsync, this version is synchronous and will not return until it is done creating the AssetBundle object.
