Render Configuration

Engines

The choice of engine decides how lights are traced in the scene.
LuxCoreRender offers the following engines (integrators):

• Path (CPU/OpenCL)
• Tiled Path (CPU/OpenCL)
• Bidir (CPU only)

Samplers

The sampler decides how points on the film are chosen (in which area to fire more/less light rays).
LuxCoreRender offers the following samplers:

• Sobol
• Metropolis

Light strategy

The light strategy controls how much processing power is spent on each light in the scene.
All lights in the scene can be sampled with the same probability (uniform light strategy), but some light sources are much brighter than others, the image will be more noisy because a lot of processing power is spent on weak lights that are not contributing much to the lighting.
The solution to this problem are the power and log power light strategies. They dedicate more processing power to lights that are brighter.

The following light strategies are available:

• Uniform
• Power
• Log Power (default)
