Lights

This section contains lights-related settings, such as lens flares effect, batching and interleaved rendering parameters as well as per-object limits for forward rendering pass.

Lights settings

Lights Settings

Deferred Lights	The value indicating if rendering of lights is enabled. enabled by default. Console access: render_lights_enabled (API control)
Lens Flares	The value indicating if rendering of per-light lens flares is enabled. enabled by default. Console access: render_lights_lens_flares (API control)

Batching Options#

Max Per Batch	The maximum number of lights rendered by a tile (see the ) per batch call. With lights batching optimization, omni lights divided into tiles are rendered in batches: each tile renders the specified number of lights per batch. It allows decreasing the number of DIP calls and increasing performance. The optimization works only for omni lights with point shape and without shadows. 0 disables batching optimization. Range of values: [32, 1024]. The default value is : 1024. Console access: render_lights_max_per_batch (API control)
Tile Grid Size	The number of grid tiles per axis for tiled rendering optimization. During this optimization, the screen space is divided into tiles that render lights in batches (see the ). The optimization works only for omni lights with point shape and without shadows. Range of values: [1, 32]. The default value is : 8. Console access: render_lights_tile_grid_size (API control)

0 disables batching optimization.

Range of values: [1, 32]. The default value is : 8.
Console access: render_lights_tile_grid_size (API control)

Interleaved Rendering Options#

Enabled	The Console access: render_lights_interleaved (API control)
Samples	The Console access: render_lights_interleaved_samples (API control)
Color Clamping	The Console access: render_lights_interleaved_color_clamping (API control)
Catmull Resampling	The Console access: render_lights_interleaved_catmull_resampling (API control)

Forward Per-Object Limits#

Ambient	The value indicating if the transparent ambient pass is rendered. Notice This option takes effect only when the forward rendering pass is used for transparent objects rendering. enabled by default. Console access: render_transparent_ambient (API control)
Lights	The value indicating if the transparent light pass is rendered. Notice This option takes effect only when the forward rendering pass is used for transparent objects rendering. enabled by default. Console access: render_transparent_light (API control)
Multiple Environment Probes	The value indicating if the transparent multiple environment probes pass is rendered. Notice This method takes effect only when the forward rendering pass is used for transparent objects rendering. enabled by default. Console access: render_transparent_multiple_env_probes (API control)
World	The maximum number of World lights per object (available only for materials rendered in the forward rendering pass). You should set the nonzero value to increase performance: it is not recommended to use more than 4 World lights per object. Range of values: [0, 128]. The default value is : 4. Console access: render_lights_forward_per_object_world (API control)
Omni	The maximum number of Omni lights per object (available only for materials rendered in the forward rendering pass). You should set the nonzero value to increase performance: it is not recommended to use more than 4 Omni lights per object. Range of values: [0, 128]. The default value is : 4. Console access: render_lights_forward_per_object_omni (API control)
Proj	The maximum number of Projected lights per object (available only for materials rendered in the forward rendering pass). You should set the nonzero value to increase performance: it is not recommended to use more than 4 Projected lights per object. Range of values: [0, 128]. The default value is : 4. Console access: render_lights_forward_per_object_proj (API control)
Environment Probe	The maximum number of Environment Probes per object (available only for materials rendered in the forward rendering pass). You should set the nonzero value to increase performance: it is not recommended to use more than 4 Voxel Probes per object. Range of values: [0, 128]. The default value is : 4. Console access: render_lights_forward_per_object_env (API control)
Voxel Probe	The maximum number of Voxel Probes per object (available only for materials rendered in the forward rendering pass). You should set the nonzero value to increase performance: it is not recommended to use more than 4 Voxel Probes per object. Range of values: [0, 128]. The default value is : 4. Console access: render_lights_forward_per_object_voxel (API control)
