OpenCL engines can run on GPUs, CPUs and other types of computing devices, they require OpenCL to run. Render scaled down film for the first few frames after a scene edit (to make interactions more fluid) Supports the same properties as "PATHCPU" plus the following: The sampler must be set to RTPATHCPUSAMPLER when using this engine. The path depth where Russian Roulette starts to be usedĮngine optimized for interactive scene editing and camera movement. LION has an intensity-weighted average diameter of 52 nm (polydispersity index 0.2) measured by dynamic light scattering. Warm up period for the convergence test expressed in samples per pixel Set to 0 to disable (so rendering will stop at the noise level) Multiply noise level with this number when all tiles have met the previous noise level. Re-render the image until a halt threshold is met or indefinitely The sampler must be set to TILEPATHSAMPLER when using this engine.Īll diffuse/glossy/specular samples are multiplied with the squared aa size: final_samples = aa^2 * (diffuse^2 + glossy^2 + specular^2) 0.0 = disabledĮnable when rendering with transparent film and premultiplied alpha, to avoid artifacts with semi-transparent areasīiased path tracer with many control options and support for tile rendering. Samples brighter than this value are clamped, helps to reduce fireflies. The threshold over which Russian Roulette is used The path depth where Russian Roulette stars to be used The following CPU engines are available: "PATHCPU"Ī path tracer with full image plane rendering (i.e. The number of threads will be used for the rendering Save the resume rendering file every specified amount of time (value in seconds). ![]() Options related to periodic save operations. Two images rendered with the same seed will have the same noise pattern. The global seed value that is used to generate random numbers. A backup of the output is always valid even in the case of a system failure 1.3.4 Experimental and debugging enginesĮnable/disable "safe save" mode for resume rendering file.
