This ensures that the light cache is consistent across computers with a different number of CPUs. Each pass is rendered in a separate thread independently of the other passes.

Number of passes - The light cache is computed in several passes, which are then combined into the final light cache.

The actual number of paths is the square of the subdivs (the default of 1000 Subdivs means that 1 000 000 paths will be traced from the camera.)

Subdivs - This determines how many paths are traced from the camera.

In the 'Light Cache' rollout, put 3000 for 'Subdivs' and set the 'Number Of Passes' to 5.

Each of the bounces in the path stores the illumination from the rest of the path into a 3D structure, very similar to the photon map Light Cache - The light map is built by tracing many eye paths from the camera.

This mode will not clip bright colors, but will instead saturate them. This can be useful to prevent Burn-outs in very bright areas (for example around light sources etc).

Adaptive subdivision - This sampler divides the image into an adaptive grid-like structure and refines depending on the difference in pixel Intensity.Īlso in the 'Color Mapping' rollout, change the color mapping 'Type' to 'Exponential', this mode will saturate the colors based on their brightness.

Adaptive DMC - This sampler takes a variable number of samples per pixel depending on the difference in the intensity of the pixels.

Fixed - This sampler always takes the same number of samples per pixel.

Image sampler refers to an algorithm for sampling and filtering the image function.

In the 'Image Sampler (Antialiasing) rollout, select 'Adaptive DMC' for the 'Type', and 'Catmull-Rom' as the 'Antialiasing Filter'.

Off - The default lights in the scene will be always switched off.

Default lights - Allows you to control the default lights in the scene.

In the steps below we will do the render settings in V-Ray, press 'F10' and then in the 'Global Switches' rollout uncheck 'Default Lights '.
