Technical Specifications: Parameters

 

1. 2D Point Light

The Point Light provides omnidirectional illumination from a central point, featuring four intuitive control groups.

• 00_Light_Control (Core Settings)
  • Light_Color: Sets the emissive color of the light source.
  • Light_Intensity: Controls the overall brightness and power of the light.
  • Light_Radius: Defines the effective radius of the light's reach.
• 01_Appearance (Visuals)
  • Hardness: Adjusts the density and sharpness of the light's core.
  • Light_Pow: Controls the falloff curve, determining how smoothly the light fades towards the edges.
  • Light_Alpha_Mul: A weight multiplier for fine-tuning the final opacity output.
• 02_Animation (Dynamic Effects)
  • Blink_Speed: Sets the frequency of the light's flickering animation.
  • Blink_Mul: Adjusts the intensity range of the flickering effect.
• 03_Advanced (Technical)
  • CenterPosX / Y: Allows for manual offset adjustment of the light's center coordinates.
  • Light_Prev_Max: Limits the maximum threshold for previews or rendering.

 

 

2. 2D Spot Light

The Spot Light provides directional illumination with specific angles, including advanced atmospheric effects like dust particles.

• 01_Spot_Shape (Geometry)
  • Spot_Angle: Sets the angular spread of the cone-shaped light.
  • Spot_Divide: Determines the horizontal expansion rate, controlling the sharpness of the cone.
  • Spot_Rot: Provides full 360-degree control over the light's rotation.
  • Spot_Start_Offset: Adjusts the apex starting point to soften the light's origin.
• 02_Spot_Appearance (Atmosphere)
  • Spot_Color / Alpha: Defines the color and final opacity of the spotlight.
  • Spot_Attenuation: Sets the rate at which the light fades over distance and environment.
  • Spot_Pow: Controls the internal density distribution within the light cone.
  • Spot_Post_Mul: A master multiplier applied to the final brightness after all calculations.
• 03_Spot_Dust (Visual Detail)
  • Dust_Tex: Assigns the texture for dust/particles flowing within the light beam.
  • Dust_Rate: Controls the animation speed of the moving dust particles.
  • Dust_Tiling: Adjusts the scale and repetition of the dust texture.
