Engine Capabilities

[MulleDK19]

Amnesia uses the same base engine as Penumbra last I checked.

No, it uses a new engine written from scratch.

Both engines uses Collada, though, so you could possibly import the models, with a few changes.


But it wouldn't be legal in either way.

Ah ok. I just had a look online and found that the Penumbra series uses the HPL Engine 1, while Amnesia uses the new and improved HPL Engine 2.

I'm not very knowledgeable on the subject, but I usually wouldn't see many limitations if it's just importing models despite the engine difference. That is unless we say that the HPL Engine 2 is indeed built from scratch and not heavily modified (why build something from scratch again when you can use what you have to help save an incredible amount of time and effort?).

It is rewritten from scratch.

There are various reasons. Slobby coding in the old engine, or simply because it's easier, etc.

It depends on whether the two games use the same model format.

And their is the legal issue of using models and textures that are both, not yours and not provided with the tools.

Both HPL and HPL2 uses Collada for both maps and models, but I doubt both engines uses the same properties for entities, etc.

The HPL1 viewer is not capable of viewing HPL2 models.
