About

This orb shader has been created in Unreal Engine. The shader can be used as a standalone material, or in conjunction with a particle effect. With a few minor tweaks to the opacity mask, the shader would be a fully functional health or mana system. The shader is interactive through exposed material parameters, which allow the developer to modify various properties.

Orb parameters:

Fresnel

  • Outer Fresnel Strength: Controls the outer fresnel strength.
  • Inner Fresnel Strength: Controls the inner fresnel strength.

General

  • Metallic: Controls the metallic surface property.
  • Roughness: Controls the roughness surface property.
  • Specular: Controls the specular surface property.
  • Emissive Strength: Controls the emissive strength.

Normal Map

  • Normal Map Texture: Allows you to input a normal map texture.
  • Normal Map Strength: Controls the normal map strength.
  • Normal Map Tiling & Offset: Controls the UV tiling and offset. RG = Tiling, BA = Offset. (Use a negative tiling value to flip the UVs.)
  • Normal Map Rotation: Controls the rotation angle and anchor point position. R = Angle, G = Anchor point U axis, B = Anchor point V axis. (Use degrees for rotation angle)

Texture

  • Texture: Allows you to input a normal map texture.
  • Texture Tiling & Offset: Controls the UV tiling and offset. RG = Tiling, BA = Offset. (Use a negative tiling value to flip the UVs.)
  • Texture Rotation: Controls the rotation angle and anchor point position. R = Angle, G = Anchor point U axis, B = Anchor point V axis. (Use degrees for rotation angle)
  • Texture Contrast: Controls the texture contrast.
  • Color 1: Controls the texture map colors.
  • Color 2: Controls the texture map colors.
  • Color Contrast: Controls the color contrast.
  • Animation Speed: Controls the animation speed.
