An unofficial engine patch for Thief: The Dark Project, known as NewDark, has introduced a significant new feature: dynamic shadows. This update, version 1.29, brings hardware transform and lighting (HTL) to the Dark Engine, enabling GPU-driven effects within the game's gothic steampunk world. This enhancement is particularly notable as it will not be present in Nightdive Studios' upcoming official remaster of the title.
The dynamic shadows cast by moving objects, such as guards, doors, and the player character Garrett himself, were showcased in a YouTube video by Thief fan Bentraxx. The visual impact of these shadows is considerable, but the update also introduces mechanical implications. For instance, opening a door can now flood a dark corridor with light, and closed doors can create shadows that Garrett can use as hiding places.
Conversely, these dynamic shadows can also pose a risk. NPCs can now detect Garrett's shadow, potentially spotting him if he is backlit. Bentraxx notes that in The Dark Project, Garrett's shadow appears as a simple box shape due to his character model's design, whereas in Thief 2, it takes on a more humanoid form.
Beyond dynamic shadows, NewDark 1.29 incorporates additional graphical enhancements. These include dynamic reflections, normal mapping, parallax occlusion mapping, SSAO, volumetric light and fog, underwater effects, and post-processing effects like luminance adaptation and light streaks. These features bring the game's lighting closer to the style seen in Thief: Deadly Shadows and the Doom 3 total conversion, The Dark Mod.
The NewDark 1.29 patch is available via the TTLG forums, though access currently requires premium membership to storage.to. While these community-driven enhancements are impressive, they do not render Nightdive's official remaster obsolete. Nightdive's focus remains on preserving the original game's integrity while improving elements such as models and animations, rather than fundamentally altering gameplay mechanics. The studio has also confirmed that the remaster will feature a new campaign titled The Tarnished Mirror.
