Research direction

Start by locating the Essence Engine and Rayne Engine detection rules and inspect how .sga files are matched. Compare the rules against the Steam depot file lists for apps 1701130 and 919730. Done means both games are detected as Rayne Engine rather than Essence Engine, without incorrectly changing other detections.

Description

False positive
SteamDB link to the game

https://steamdb.info/app/1701130/
https://steamdb.info/app/919730/

What is it being detected as and what should it be detected as? Any other information?

Both listed games are incorrectly detected as using Essence Engine, but they actually use Rayne Engine.
The false positive appears to come from detection of .sga files.

  • In Essence Engine, .sga files are archive containers.
  • In Rayne Engine, .sga files store animation/skeleton data used alongside .sgm model files.
