A Voronoi-based Lava effect which separates two layers of textures according to their distance from the edges between Voronoi cells.

Parameters

Surface Options

  • Workflow Mode - Choose between Metallic and Specular workflows. This affects how the shader calculates lighting and changes some of the options presented to you.
  • Surface Type - Toggle between Opaque and Transparent rendering.
  • Render Face -Choose whether to render Front, Back, or Both faces
  • Alpha Clip - Toggle whether the shader should apply the Alpha Clip Threshold.
  • Alpha Clip Threshold - Pixels with final base color alpha values below this threshold will be culled if Alpha Clip is enabled.
  • Receive Shadows - Toggle whether realtime shadows should be applied to the object.

Voronoi Properties

  • Voronoi density - How tightly packed the Voronoi cells are.
  • Voronoi Angle Offset - A parameter for creating the Voronoi cells. Use values above zero.
  • Voronoi Thickness - Width of the edges between Voronoi cell shapes. This controls the distribution of Layer 1 and Layer 2 pixels.
  • Voronoi Falloff - Smooth falloff region between both texture layers.

First Layer Properties

  • Base Color - The albedo color of the object. The alpha channel may be used for transparency.
  • Base Texture - Similar to Base Color, can be used to change the albedo color of the object. The tiling and offset settings used for this texture are applied to the other Lit textures supplied to the material.
  • Metallic - Appears only in Metallic workflow mode. Controls how metallic the object is – 1 means the object is fully metallic, whereas 0 means it is completely non-metallic.
  • Specular Color - Appears only in Specular workflow mode. Controls the color of specular highlights that appear on the object’s surface.
  • Smoothness - A value between 0 and 1 representing how smooth the surface is. Rough surfaces tend to have no specular highlights, while totally smooth surfaces tend to have small, bright highlights. The smoothness value is equal to the texture sample multiplied by the slider value.
  • Convert From Roughness - Some 3D modelling packages output roughness textures instead of smoothness textures. Ticking this option will convert a roughness texture applied to the Smoothness slot into smoothness data.
  • Normal Map - A texture representing normal vector directions on the object surface. The slider controls the strength of the augmented normal vector data.
  • Heightmap - A texture which lets you simulate raised or lowered parts of the surface using UV offsets. Using this option incurs an increased performance impact.
  • Ambient Occlusion - The amount of lighting that falls into small crevices on the object surface. 1 means the surface is fully lit, while 0 means that part of the surface is obscured (occluded).
  • Emission Color - Applies an emissive color to the surface, which will be visible regardless of whether the object is in shadow.

Second Layer Properties

Same as each of the First Layer Properties as seen above.
