> The scene file names are stored as CRC hashes in the file. Because hash
> is one-direction thing, I have to parse scene names from maps' entity
> lumps and hash them.
>
> But I have a problem. In scenes.image, the hashes (or not hashes, in
> source code they're called crcFilename) increment from file to file,
> from somewhere near 0x00000000 to somewhere near 0xffffffff. It doesn't
> really look like a CRC hash, because CRC is completely random and
> randomly changes if even a single bit was modified. When I hash scene
> names in maps, they are completely different.
>
> And it doesn't appear that the hash is stored in the binary scene
> itself. It isn't the scene's CRC either.
>
> Please help if you know the format. Thanks in advance.
