I've uploaded beta 3 of the mod. It should be downloadable soon. Much has been fixed, but I fear that maybe something has been lost. It's up to you to download it and decide for yourselves. The extra week of development was good, so much that it would have been unplayable before. Here's the changelog:
Beta 3 changelog: from beta 2.
()Players can now run, as they did in original T&A.
()Part 4 added.
()Various fixes and tweaks to various aspects of mod, including attempted AI route improvements, cinematics improvements, and such.
()Now using cubemapped reflections on character's eyes. This creates quite a pleasing effect when compared to the original T&A eyes.
()Added easy switch for HDR lighting, and fixed all known instances where it caused visual errors with boolean checking.
()The HDR compatibility required reworking the credits, because the renderer was oversaturating everything.
()Fixed settings corruption. (Hopefully.)
