using samples in blender cycles render layer tab I recently ran into the samples in the blender cycles layer tab (see picture). Somewhere I read I could change the sample rate for a specific layer. This can be useful if one layer doesn't need as many sample rates as others.

Does someone know how to use this? Would be awesome.

As indicated by the tooltip when hovering the mouse pointer over it, the Render Layer Samples setting allows you to override the Number of samples used. Setting it to 0 (the default) tells Blender to use whatever is the default for the scene (ie, the number of samples set in the Samples panel of the Render properties). Setting it to a non-zero value will use that number of samples for that render layer.

Eg, setting it to ‘1’ will render that layer as if the Render Samples is set to 1.
