Considering the last trends in real time rendering productions and how the responsivity in terms of prototypes validation is needed by design companies, Unity introduces the HDRP technology to compete with the stunning graphic impact of Unreal Engine.
The Lexus LC 500 teaser part I, at top of the page, is a demo released by Unity mixing the HDRP technology and CAD optimising tools released by PiXYZ.
The principles of the HDRP (High Definition Render Pipeline) are:
Physically based rendering
Unified and coherent lighting
Features independent of the rendering path.
Physically based rendering relies on three pillars: Lighting, Material, and Camera. Lighting and material rely on physical interaction and there should be a clear decoupling between them to get a coherent result under various lighting conditions. The camera interprets how the resulting lighting will be displayed on the screen. The goal is to make it easier for the artists to achieve a plausible result.
Unified lighting means that all objects and participating media in the scene should receive the same lighting. There shouldn’t be any distinction between opaque, transparent or volumetric materials. Coherent lighting means that a material must interact correctly with the lighting produced by any light sources (reflection probe, area lights…), even when modified by a Decal for example. This results in a more coherent look.
There are various rendering passes used in real-time rendering: Deferred/Forward, SinglePass/Multipass, Tile/Cluster… It is common in game development that the selection of a rendering path limits the set of graphics features. For HD RP we have tried to get the same set of graphics features whatever the rendering path. The result is that the choice of a rendering path is solely based on performance and not on which features are required for a game. More onHDRP technology here.
To boost the presence in the Automotive and Transportation market, Unity has partnered with PiXYZ Studio, a company that has released a complete software suite to manipulate, optimise and import CAD data format into game engines, included Unreal Engine.
The Lexus LC 500 teaser is the result of a collaboration between the companies teams and much more about the project making of can be read here.
