.. _bpy.types.ShaderNodeVolumePrincipled: ***************** Principled Volume ***************** .. figure:: /images/render_shader-nodes_shader_volume-principled_node.png :align: right Principled Volume. The *Principled Volume* shader combines all volume shading components into a single easy to use node. Volumes like smoke and fire can be rendered with a single shader node, which includes scattering, absorption and blackbody emission. Inputs ====== Color Volume scattering color. Color Attribute Volume grid for coloring the volume. Use "color" for smoke simulations. Density Density of the volume. Density Attribute Volume grid to define the density, typically "density". Anisotropy Backward or forward scattering direction. Absorption Color Volume shadow color tint. Emission Strength Amount of light to emit. Emission Color Emission color tint. Blackbody Intensity Blackbody emission for fire. Set to 1 for physically accurate intensity. Blackbody Tint Color tint for blackbody emission. Temperature Temperature in kelvin for blackbody emission, higher values emit more. Temperature Attribute Volume grid to define the temperature, typically "temperature". Outputs ======= Volume Standard shader output. Examples ======== .. figure:: /images/render_materials_components_volume_principled.jpg
