Which engines are cross-compatible? I know UE5 is backwards compatible with UE4. UE3 to UE4 is a no-go.
Of course you can do a remake of a game in the same engine - it just never happens, so it's not something to make a debate about. If every debate was about making extreme unlikely scenarios, we would'nt get far.
So it's a remake..
Definitely a remaster.. "Porting a
Goldsource model to the Source engine is a short process. For best results, have all original source content ready for the model: original 3d package file, textures, and
.QC file.
SMD files may also be useful if the original 3d package file is unavailable.
For the most part, porting models is straightforward: Set the
VPROJECT properly, convert old textures to
VTF format, tweak .QC file to include new Source syntax, and then compile the new content into a new Source model file." -

Guess it was backwards compatible?
