Searching Doom by Humus (not a perfume), I can link to this post:
It's an old format. If IDs are not directly maintained when migrating then you can't do simple regular expression conversion and need to use lookup tables. Xenforo supports both but it could be that neither was done during migration.
Thanks Shify but it was an earlier post from when Humus, found evidence that part of Doom 3's lighting interaction was originally planned to be done via shader math instead of via texture lookup. Humus re-enabled this method and modified the way it worked so that ATI hardware gained significant performance
Shortly after Doom 3 was released, one of the best Demo coders out there, Humus, found evidence that part of Doom 3's lighting interaction was originally planned to be done via shader math instead of via texture lookup.

BTW @Albuquerque you can certianly use URLs with brackets and other formatting symbols, it works fine with regular [URL] tag syntax - you can simply paste the bare URL into the text edit form and it auto-converts to code tags: [URL unfurl="true"]https://forum.beyond3d.com/search/7540/?page=8&c[older_than]=1121017390&c[users]=Humus&o=date[/URL]
Or use the extended tag syntax which encloses the actual URL in single or double quotes - the latter is the default behavior of the 'Insert Link (Ctrl+K)' button on the toolbar: [URL='https://forum.beyond3d.com/search/7540/?page=8&c[older_than]=1121017390&c[users]=Humus&o=date'] Search all posts by Humus older than...[???][/URL]
