unreal.MaterialExpressionRuntimeVirtualTextureSample

class unreal.MaterialExpressionRuntimeVirtualTextureSample(outer: Optional[Object] = None, name: Union[Name, str] = 'None')

Bases: MaterialExpression

Material expression for sampling from a runtime virtual texture.

C++ Source:

  • Module: Engine

  • File: MaterialExpressionRuntimeVirtualTextureSample.h

Editor Properties: (see get_editor_property/set_editor_property)

  • adaptive (bool): [Read-Write] Adaptive: Enable sparse adaptive page tables. Note that the bound Virtual Texture should have valid adaptive virtual texture settings for sampling to work correctly.

  • desc (str): [Read-Write] Desc: A description that level designers can add (shows in the material editor UI).

  • material_expression_editor_x (int32): [Read-Write] Material Expression Editor X

  • material_expression_editor_y (int32): [Read-Write] Material Expression Editor Y

  • material_type (RuntimeVirtualTextureMaterialType): [Read-Write] Material Type: How to interpret the virtual texture contents. Note that the bound Virtual Texture should have the same setting for sampling to work correctly.

  • mip_value_mode (RuntimeVirtualTextureMipValueMode): [Read-Write] Mip Value Mode: Defines how the mip level is calculated for the virtual texture lookup.

  • single_physical_space (bool): [Read-Write] Single Physical Space: Enable page table channel packing. Note that the bound Virtual Texture should have the same setting for sampling to work correctly.

  • texture_address_mode (RuntimeVirtualTextureTextureAddressMode): [Read-Write] Texture Address Mode: Defines the texture addressing mode.

  • virtual_texture (RuntimeVirtualTexture): [Read-Write] Virtual Texture: The virtual texture object to sample.
