I have done an optimization to the cooking process which involves changing how the CRCs are generated. Everything works ok but the issue is that on the cooking process the CRCs for the pak files (and I have no idea what they are) always have bad CRCs. The result is that OGGs need to be regenerated and that doesn’t allow me to profile what I want. Also the cooking process complains of reflection captures not being valid even though I went into the editor, did a build, and saved the map, but I’m not sure if that’s related to the CRC. How can I generate the CRCs for the pak files so that they are ok?
Here is some sample output:
