Values above 1 (original diffuse color) aren’t physically correct, but they can be useful as an art direction knob to increase the amount of bounced light in the scene. Best to keep below 2 as it also causes reflections to be brighter than the scene.lumen_final_gather_lighting_update_speed(float): [Read-Write] Controls how much Lumen Final Gather is allowed to cache lighting results to improve performance. Larger scales cause lighting changes to propagate faster, but increase GPU cost and noise.lumen_final_gather_quality(float): [Read-Write] Scales Lumen’s Final Gather quality. Larger scales reduce noise, but greatly increase GPU cost.lumen_front_layer_translucency_reflections(bool): [Read-Write] Whether to use high quality mirror reflections on the front layer of translucent surfaces. Other layers will use the lower quality Radiance Cache method that can only produce glossy reflections. Increases GPU cost when enabled.lumen_full_skylight_leaking_distance(float): [Read-Write] Controls the distance from a receiving surface where skylight leaking reaches its full intensity. Smaller values make the skylight leaking flatter, while larger values create an Ambient Occlusion effect.lumen_max_reflection_bounces(int32): [Read-Write] Sets the maximum number of recursive reflection bounces. 1 means a single reflection ray (no secondary reflections in mirrors). Currently only supported by Hardware Ray Tracing with Hit Lighting.lumen_max_trace_distance(float): [Read-Write] Controls the maximum distance that Lumen should trace while solving lighting. Values that are too small will cause lighting to leak into large caves, while values that are large will increase GPU cost.lumen_ray_lighting_mode(LumenRayLightingModeOverride): [Read-Write] Controls how Lumen rays are lit when Lumen is using Hardware Ray Tracing. By default, Lumen uses the Surface Cache for best performance, but can be set to ‘Hit Lighting’ for higher quality.lumen_reflection_quality(float): [Read-Write] Scales the Reflection quality. Larger scales reduce noise in reflections, but increase GPU cost.lumen_scene_detail(float): [Read-Write] Controls the size of instances that can be represented in Lumen Scene. Larger values will ensure small objects are represented, but increase GPU cost.lumen_scene_lighting_quality(float): [Read-Write] Scales Lumen Scene’s quality. Larger scales cause Lumen Scene to be calculated with a higher fidelity, which can be visible in reflections, but increase GPU cost.lumen_scene_lighting_update_speed(float): [Read-Write] Controls how much Lumen Scene is allowed to cache lighting results to improve performance. Larger scales cause lighting changes to propagate faster, but increase GPU cost.lumen_scene_view_distance(float): [Read-Write] Sets the maximum view distance of the scene that Lumen maintains for ray tracing against. Larger values will increase the effective range of sky shadowing and Global Illumination, but increase GPU cost.lumen_skylight_leaking(float): [Read-Write] Controls what fraction of the skylight intensity should be allowed to leak. This can be useful as an art direction knob (non-physically based) to keep indoor areas from going fully black.lumen_surface_cache_resolution(float): [Read-Write] Scale factor for Lumen Surface Cache resolution, for Scene Capture. Smaller values save GPU memory, at a cost in quality. Defaults to 0.5 if not overridden.mobile_hq_gaussian(bool): [Read-Write] Enable HQ Gaussian on high end mobile platforms. (ES3_1)motion_blur_amount(float): [Read-Write] Strength of motion blur, 0:offmotion_blur_max(float): [Read-Write] max distortion caused by motion blur, in percent of the screen width, 0:offmotion_blur_per_object_size(float): [Read-Write] The minimum projected screen radius for a primitive to be drawn in the velocity pass, percentage of screen width. smaller numbers cause more draw calls, default: 4%motion_blur_target_fps(int32): [Read-Write] Defines the target FPS for motion blur. Makes motion blur independent of actual frame rate and relative to the specified target FPS instead. Higher target FPS results in shorter frames, which means shorter shutter times and less motion blur. Lower FPS means more motion blur. A value of zero makes the motion blur dependent on the actual frame rate.override_ambient_cubemap_intensity(bool): [Read-Write]override_ambient_cubemap_tint(bool):
