old amnesia complete asset

[Abion47]

its possible to convert all amnesia object together? there is amnesia mod but few objects. just castlebase and cellar base. but no dungeon and another.. I want to make amnesia style of level but with SOMA engine

It's certainly possible for anyone willing to put in the work. Many of the entities can almost be imported as-is, but a lot also require slight tweaking. At the worst, though, the models and textures all use more or less the same formats, so if you wanted you could recreate the entities in SOMA using the Model Editor.

That being said, if all you are going to do is create an Amnesia custom story in SOMA, I'd recommend just sticking to Amnesia. The new graphics upgrades and shaders in HPL3 really bring out the flaws and datedness in the Amnesia assets, especially if you use SOMA assets alongside them.
