Epic Games has posted a video showing details of the new materials workflow in Unreal
As far as we’re aware, the footage is the first public glimpse beneath the hood of the game engine, previously seen mainly in more carefully stage-managed presentations, such as the recent Infiltrator demo.
The video is fairly brief, but the Unreal Engine website goes into more details about potential benefits of a layered material workflow, including the power to paint maps at a per-pixel level and change mapping at run-time, or animate layer masks.
Epic tells us that the video will be the first in a series focusing on other new features from the engine, and how they integrate into games pipelines – including a look at how parts of the Infiltrator demo itself were created.
