PCGVolume Sampler Settings

C++ Source:

  • Plugin: PCG

  • Module: PCG

  • File: PCGVolumeSampler.h

Editor Properties: (see get_editor_property/set_editor_property)

  • break_debugger (bool): [Read-Write] If a debugger is attached, triggers a breakpoint inside IPCGElement::Execute(). Editor only. Transient.

  • category (Text): [Read-Write]

  • debug (bool): [Read-Write]

  • debug_buffer_size (int32): [Read-Write] Size (in number of floats) of the shader debug print buffer.

  • debug_settings (PCGDebugVisualizationSettings): [Read-Write]

  • description (Text): [Read-Write]

  • determinism_settings (PCGDeterminismSettings): [Read-Write]

  • dump_cooked_hlsl (bool): [Read-Write] Dump the cooked HLSL into the log after it is generated.

  • dump_data_descriptions (bool): [Read-Write] Dump the data descriptions of input/output pins to the log.

  • enabled (bool): [Read-Write]

  • execute_on_gpu (bool): [Read-Write] Whether this node should be executed on the GPU.

  • expose_to_library (bool): [Read-Write]

  • point_steepness (float): [Read-Write] Each PCG point represents a discretized, volumetric region of world space. The points’ Steepness value [0.0 to 1.0] establishes how “hard” or “soft” that volume will be represented. From 0, it will ramp up linearly increasing its influence over the density from the point’s center to up to two times the bounds. At 1, it will represent a binary box function with the size of the point’s bounds.

  • print_shader_debug_values (bool): [Read-Write] Enable use of ‘WriteDebugValue(uint Index, float Value)’ function in your kernel. Allows you to write float values to a buffer for logging on the CPU.

  • seed (int32): [Read-Write]

  • unbounded (bool): [Read-Write] If no Bounding Shape input is provided, the actor bounds are used to limit the sample generation domain. This option allows ignoring the actor bounds and generating over the entire volume. Use with caution as this may generate a lot of points.

  • use_seed (bool): [Read-Write] deprecated: Implement the PCGSettings virtual UseSeed() override.

  • voxel_size (Vector): [Read-Write]
