This adaptively updates the light selection in direct light sampling, to help learn the current scene and where the lights are in that scene.
AI Light option is useful when the scene has complex lighting, for example a large scene with a lot of lights individually affecting a small local area in direct light coupled with the light emitters having a lot of polygons.Įnables dynamic AI light update. The "tool" must always be fit for the purpose. These two tools are completely to ease your work, not to create miracles. Remember, never use low samples when using AI Light or AI Denoiser. However, for the quality factor, it still needs your eyes and your point of view, which you cannot produce artificially. The following scene obviously needs more samples but AIs have done their job properly.
However, the low number of samples is not good enough for AIs to learn the scene. In the below picture, AI Light and AI Denoiser are used together. If you use AI denoiser and/or Adaptive sampling, you can achieve much better results. Just as we explained in AI Denoiser, "Data" is needed for AI to learn the scene and work efficiently.That's exactly what AI Light does. However, AI Light can make smoother and cleaner renderings as the number of samples increases. It is interesting that the AI Light function to learn about the scene and create a render strategy accordingly. The difference is obvious when AI light is on. We suggest you read it.Īs you can see in the test, we used 128 samples to render both AI Light on and off. We made a detailed explanation about "Blackbody" subject in the this section. The lights on the floor were created with cloner and cloner cubes have emissive material (ie blackbody emission). The scene is from the content browser of Cinema 4D. To test AI light, you can make a setup as you see in the picture below. When used with Adaptive Sampling, AI Light gets even better, since it will learn that other lights become more important, as some pixels are no longer sampled. The learning is all done in the renderer, it is fully unbiased and tracks emissive points live and in real time. As a learning system, AI Light improves as more samples are rendered. Octane’s Artificially Intelligent Light provides a great improvement in light sampling, especially in scenes that have many lights with localised distributions. However, note that GI clamp is a biased clamping method used to reduce fireflies, therefore it is possible the use of GI clamp can result in slightly different brightness in parts of the image between the old light sampling and AI Light. It is designed to learn the scene that it is rendering and improve its sampling strategy over the course of rendering the image. You can find the Octane Light kit here.AI Light is a lighting algorithm in Octane V4, and is implemented so that there is no difference in the resulting rendered image for unbiased rendering. Spotlight with Gobo support and some Gobo textures are included.There are scripts for each Light that you can use to integrate them into your Layout. You don´t have to use the Content Browser to put light in the scene.Copy lights easily, with same controls.Lights are preconfigured with all settings (also texture projections).
Solo or Un-solo all 4dm lights with a button.Use the Cinema Light placement tool for moving lights, specular or targeting lights.Supports all lights (Area/Shape, Spot- and Sunlight, HdriSky, Seamless Floor) with simple settings (all settings in one tab).With it, you are able to move lights, set targets for the lights, and set the specular controls. The lighting setup has all the light attributes in one convenient place. The kit has area and shape lights, spotlights (with in view visualization), sun and HDR sky lights. His Octane Light Kit is a simple and easy to use light setup for Octane. His latest is a handy Light Kit for Cinema 4D Octane users.
