Furthermore, these are done without the user having to set up light probes or do any other manual tasks. Now users can get a more interactive experience like EEVEE with more physically correct soft shadows and reflections and refractions. Most of these benefits are realized in the viewport, for lookdev: setting up scenes, and changing lighting, shaders, etc. There are two huge benefits for artists with this implementation of Radeon ProRender: it is an all-in-one solution, and it helps to fill a wide gap between OpenGL viewports (such as EEVEE) and full path-tracers (like Cycles).

And using the universal Radeon ProRender SDK allows the developer and user to change the quality and speed of rendering in only a few lines of code. Minimal changes to the Blender plug-in were made to take advantage of this. The other great part here is for developers.

Dialing up or down these effects is what allows Full Spectrum Rendering to scale for speed and quality. The end effect of the renderer is to harness all the power of the GPU, including taking advantage of GPU ray tracing acceleration where available. These effects are achieved using compute shaders and smart denoising. However, it uses Vulkan for faster rendering, and then can add ray traced effects such as reflection, refraction, and ambient occlusion. This new rendering backend uses rasterization to render the scene like many game engines or the EEVEE viewport renderer in Blender. We use the same Radeon ProRender SDK, but have a different rendering backend for Full Spectrum Rendering. In essence, Full Spectrum Rendering is an extension of Radeon ProRender beyond 'just' a path traced renderer using OpenCL. This gives artists a viewport that can be scaled from super-fast rasterized to fully ray traced, all with physically accurate materials and lighting.

Today, we are providing a beta preview of Radeon ProRender with Full Spectrum Rendering in our Blender 2.80 addon.
