Also on the topic of extracting 3d models to find secret codes, doesn’t UE4 and other applications change the exact position of vertexes, so that precision limitations and compression would hide/remove any secret data put into vertex positions? Like if the a vertex position was x 12.43561 y 24.42361 z 4.53461 before importing it in UE4, it’s very likely that the .00061 (and any other hidden math) would be destroyed.
