Flashlight-v2 (PSX)

Note: This game asset is only compatible with Unity's URP pipeline.

The demo includes a demonstration scene and several prefabs, showing how to use a hollow cone to fake volumetric light.

Important Assets

• Flashlight/Model/Open Cylinder.fbx
  A cone-shaped model with a cap and base, 1 meter in height, used to fake volumetric light.
• Flashlight/Materials/ShaderGraph/FakeVolumetric.shadergraph
  A simple shader graph for controlling the "fake" volumetric light material effect. After creating a material from it and assigning it to the hollow cone model, you can adjust the model's Z scale to change the beam length, and tweak the following material properties:
  • MainTex (Texture2D): Can be left empty, but it is recommended to use a gradient light texture (a suitable one is included in the asset).
  • Range (float): Controls the size of the small end of the hollow cone. There is no specific unit; adjust according to the visual result.
  • Alpha (float): Overall transparency.
  • Density (float): Controls the attenuation of transparency.
• Flashlight/Materials/UnityLit_FakeVolumetric.mat
  This is a Unity Unlit material, set to Transparent, Additive blending mode, and Two-sided rendering. Drag a light gradient image into the BaseMap slot, then assign this material to the hollow cone model to create fake volumetric light.

Additional Components

• A simple player controller: SimpleCharacterController.
• A flashlight controller script: Flashlight.cs. Press the middle mouse button to toggle it on/off, and scroll the mouse wheel to adjust the light focus. For more details, refer to my other asset: Flashlight.
