unreal.NiagaraSystemScalabilitySettings

class unreal.NiagaraSystemScalabilitySettings

Bases: StructBase

Scalability settings for Niagara Systems for a particular platform set (unless overridden).

C++ Source:

  • Plugin: Niagara

  • Module: Niagara

  • File: NiagaraEffectType.h

Editor Properties: (see get_editor_property/set_editor_property)

  • budget_scaling (NiagaraGlobalBudgetScaling): [Read-Write] Settings related to scaling down FX based on the current budget usage.

  • cull_by_distance (bool): [Read-Write] Controls whether distance culling is enabled.

  • cull_max_instance_count (bool): [Read-Write] Controls whether we should cull systems based on how many instances with the same Effect Type are active.

  • cull_per_system_max_instance_count (bool): [Read-Write] Controls whether we should cull systems based on how many instances of the system are active.

  • cull_proxy_mode (NiagaraCullProxyMode): [Read-Write] Controls what, if any, proxy will be used in place of culled systems.

  • max_distance (float): [Read-Write] Effects of this type are culled beyond this distance.

  • max_instances (int32): [Read-Write] Effects of this type will be culled when total active instances using this same EffectType exceeds this number. If the effect type has a significance handler, instances are sorted by their significance and only the N most significant will be kept. The rest are culled. If it does not have a significance handler, instance count culling will be applied at spawn time only. New FX that would exceed the counts are not spawned/activated.

  • max_system_instances (int32): [Read-Write] Effects of this type will be culled when total active instances of the same NiagaraSystem exceeds this number. If the effect type has a significance handler, instances are sorted by their significance and only the N most significant will be kept. The rest are culled. If it does not have a significance handler, instance count culling will be applied at spawn time only. New FX that would exceed the counts are not spawned/activated.

  • max_system_proxies (int32): [Read-Write] Limit on the number of proxies that can be used at once per system. While much cheaper than full FX instances, proxies still incur some cost so must have a limit. When significance information is available using a significance handler, the most significance proxies will be kept up to this limit.

  • platforms (NiagaraPlatformSet): [Read-Write] The platforms on which these settings are active (unless overridden).

  • visibility_culling (NiagaraSystemVisibilityCullingSettings): [Read-Write] Settings controlling how systems are culled by visibility.
