Path Tracer Tab

Setting	Description
General	Contains settings used by the path tracer or ray tracer depending on the tab you choose. Some settings are common between Path tracer and Ray Tracer. These settings include: Stroke Tolerance Depth of Field Blur Camera Projection Shadow Ignore Default Lighting Ignore Open Elements and Text Render Geometry Outside View Compute Physically Accurate Caustics
Path Tracer	Contains the following settings, specific to path tracer: Max. Samples per pixel - Controls the maximum samples per pixel used by the path tracer before the render is complete. The higher this value the better is the quality and longer is the time needed to finish. You can always set this to a higher value than you need and interrupt the render when you achieve desirable results Max. Rendering Time - This value in minutes when set, is how long to let the path tracer render before stopping. You may need to increase the number of samples if that option is checked. For example, if Max Samples per pixel is 256 and you set Max Rendering Time to 120 minutes most likely the render will stop when it hits the sample limit before reaching the time limit Render VUE Spectral cloud layers - When selected, the dynamic clear sky model will be replaced with a progressive sky environment map, filled on demand by the path tracer, that will include VUE spectral cloud layers. Note: For performance reasons, the sky environment map will always be rendered from a low altitude point of view (regardless of the actual camera placement), making it suitable for most architectural scenes. For in or above clouds points of view, it is recommended to use VUE Ray Trace renderer. PathTracer Denoiser - Options are None, NVIDIA, and Intel. Intel denoiser will be used by default, NVIDIA denoiser requires a Maxwell or later based GPU with a driver version 435.80 or higher Use Albedo and Normal passes to improve denoising - When enabled extra channels are used to improve denoising. Denoising results are much better when the denoiser can use Albedo and Normal multi-passes. When the corresponding tick is checked, these multi-passes will automatically be computed by the render engine
