Corona Renderer brings significant speedups in many situations.
Work faster. Much faster.
Speed is an important factor in any production environment, and a renderer must always deliver results as fast as possible.
As a result, we are obsessed with speed! We like to hunt for milliseconds in our own code, and are always looking for ways to cut down parsing and rendering times without forcing users to buy expensive hardware, by focusing on creating smart algorithms under the hood. In every version we release, we look to boost the speed of rendering as much as possible as well as adding new features.
Corona Renderer uses Intel Embree Ray Tracing Kernels, making the CPU–only Corona as fast as many GPU renderers but without any of the limitations of GPU–based solutions…
Denoising is seamlessly integrated into the core as a one–click solution. The denoising level can be interactively adjusted in the VFB after rendering is complete, so that you are not locked in to the level set in the rendering options. This lets you check and adjust the blending between the regular and the denoised image without having to re–render. You can also calculate Denoising in the Corona Image Editor rather than at render time and without the overhead of working in a 3D application.
To learn more about it, you can watch the tutorial from when Denoising was released:
You can change materials, lights, and create or adjust geometry and see your interactive render respond almost immediately. It runs completely on the CPU, so it has no limitations and won’t care what graphics card you have installed.
You aren’t limited to using it only for interactive rendering however – you can also use the GPU denoiser for final renders too if you choose.
Note that this denoiser requires a compatible NVIDIA graphics card. Standard denoising uses the CPU only so can be used with any graphics card.
Interactive Rendering also offers as many render regions as you like, which can be moved and resized as you choose. This means that so that they can act as a “sample brush”, letting you paint–in areas which you want to refine faster or inspect at better quality.
