Adaptive Sampling identifies noisier areas and more sampling iterations are produced for them.Clamp Radiance controls the intensity or the maximum brightness of samples in the scene. ![]() This allows you to avoid self-shadowing and lighting artifacts common with ray tracers. Ray Cast Epsilon sets an offset that moves rays of light away from the geometry for ray-surface intersection calculations.In this case, the quantity of the Render Samples is predetermined by the program itself. Max Ray Shadow controls the accuracy of shadows from transparent objects, which are similar in terms of the noise level.This parameter is used for transparent materials like glass. Max Ray Refraction indicates the maximum number of times a light ray is refracted.Max Ray Glossy indicates the maximum number of times a light ray bounces from specular surfaces.Max Ray Diffuse indicates the maximum number of times the light is reflected from the diffuse surfaces.Return to the default value of 1, if an outside scene is excessively bright. If that’s not the case, change the brightness of lamps in your project. It is used to render indoor scenes in which daylight is meant to be the main source of illumination. The Environment Light Intensity parameter adjusts the brightness of the sunlight or moonlight.When you’re satisfied with the resulting image, run the final render with the needed resolution and 100 render samples (this quantity should be enough for most projects). Experiment with different Tonemap filters that may help correct too light or dark spots on the scene. In the Filters section, it is recommended that you turn on the denoiser in the Denoise drop down list. You can run further tests increasing the image size and render samples values. The render will take about one minute, though the result will be noisy. ![]() The resolution of 800圆00 pixels and 30-50 samples will be enough for evaluating the attractiveness of the 3D scene. It will help you understand how to make your 3D scene brighter and more eye-catching. It is recommended that you start with renders of lower quality and then gradually improve the quality. Rendering duration may last very long even with the average dimensions in the Resolution list and with the number of Render Samples below 100. The tiles’ dimensions can be set up in the Tile Size field. All you need to do for switching tiling on is click on the Use Tiles option. When the process is finished, these tiles will be united into one object once again. In this case, each image can be split into multiple images or tiles, and each of them will be rendered separately. ![]() Those who need to render objects with high resolution may face a problem-their devices may not be able to support such advanced functionality due to the lack of device memory. The Stop Render and Save buttons will cancel the process and save the file. To proceed with the rendering process, you need to click the Render button. Please remember that this parameter influences the rendering process time immensely-longer rendering time means better quality. ![]() The higher number of samples you set in the Render Samples, the better the result will be. The process of creating a high-quality final image implies making many iterations, each time casting multiple light rays on each pixel and choosing the average color. You can use the predefined dimensions for your render images or adjust them with the Resolution and Size controls. You need to select the camera view you want to use for rendering in the Camera drop-down list. The CPU Threads indicates the number of CPU threads that will be used for the renders. The list of available CPU and GPU devices is located in the Render Devices box.
