The parsing of PRWM file is especially fast when the endianness of the file is the same as the endianness of the client platform.
|
|
The loader will automatically replace the <strong>*</strong> in the model url by either <strong>le</strong> or <strong>be</strong> depending on the client platform's endianness to download the most appropriate file. <a href="https://github.com/kchapelier/PRWM" target="_blank" rel="noopener noreferrer">Specifications and implementations</a><br><br>
