Si l’éditeur 64B semble acté, j'ai aussi retenu l'intégration de PowerVR Ray Tracing dans cette version..
Pre-baked lighting
The most common use case for ray tracing today is to support pre-baked lighting in the form of lightmaps or light probes. Leveraging PowerVR Ray Tracing enables light maps to be baked in near real-time.
Unity 5 is the first development platform to ship with in-editor real-time lightmap previews based on PowerVR Ray Tracing technology. This allows for near instantaneous feedback for changes to global illumination lightmaps by displaying an accurate preview in the editor's scene view of how lighting will look in the final game.
With this technology, artists can continue to iterate and refine the look of a level while final lightmaps update and bake in the background, dramatically decreasing the amount of time needed to make artistic adjustments to scenes.
