set_influence_target()

void MayaFlux::Nexus::Agent::set_influence_target

(

std::shared_ptr< Buffers::RenderProcessor >

proc

)

Set the render processor to target for GPU-side influence delivery.

Creates a UBO matching the InfluenceUBO layout, registers a binding named "u_influence" at set=1 binding=0 on the target processor, and binds the UBO. On each subsequent invoke(), the context fields are packed into the UBO automatically.

Parameters

proc	Target render processor. Must outlive this Emitter or be cleared via clear_influence_target() first.
