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.
