Pixel-Perfect Fog Of War

Pixel-Perfect Fog Of War is a line of sight tool that can project a field of view from any number of objects, and hide objects within un-seen parts of your scene.

Pixel-Perfect Fog of war is the Ultimate fog of war tool, perfect for your next RTS, Moba, Social deduction, or horror project!

Pixel-Perfect Fog Of War has many features, and advantages over its competition:

• All Render pipelines are supported
• No extra cameras or render textures are required for FOW to operate
  • No rendering overhead due to extra cameras
  • World size cannot limit FOW, it will render at full resolution no matter how vast your scene is
• Greater performance
  • Zero GC Allocations
  • Most of the FOW operations are caluclated on the GPU
  • The CPU side of FOW is accelerated using the C# jobs system and burst compiler
• Greater Customization:
  • Choose between Soft and Hard FOW
  • Fog Transparency
  • 4 fog rendering modes out of the box:
    • Solid Color
    • Gray Scale
    • Scene Blur
    • Scrolling Texture Fog
  • Scene-Wide world bounds to darken the out of bounds portion of your scene
  • Option to permanately reveal areas seen by revealers, and optionally regrow the fog slowly over time
  • Option to set revealer opacity
• No custom materials required, FOW will work out of the box with your existing scene
• Compatible with the vast majority of assets on the asset store, with support provided in the case you find an incompatibility
• Lightweight, the whole package is under 1mb!
• Easily hide GameObjects within the Fog, abstracted for easy implementation of custom behaviors!
• FOW mask generation for minimaps, with camera frustum generation
• FOW fully supports both 2D and 3D projects. For 3d fog, you can project onto any axis, and render in both orthographic and perspective cameras
• FOW will render on any graphics backend (excluding WebGL)
• Active and quick support through the discord
• Frequent feature and performance oriented updates, including most community feature requests!
• Super quick setup: get FOW in your scene in under 1 minute!

Technical details

This package has many advantages over the competition:

• Zero GC Allocations during the Update loop
• No extra camera necessary
• Compatible with all shaders. This tool using Image effects for the built-in render pipeline, render features for URP, and the Volume framework for HDRP.
• No render textures necessary. line of sight data is calculated per-pixel on the GPU.

This package utilizes the Burst Compiler and C# jobs system. You must have these packages installed for the system to work out of the box. If you cannot use these for whatever reason, contact me for a resolution.

Several Quick-Start demo scenes are included with this package.

Compatible Graphics APIs:

• DX11
• DX12
• Vulkan
• OpenGL
• OpenGL ES 2.x
• OpenGL ES 3.x
• Metal

Incompatible Graphics APIs:

• WebGL

LIMITATIONS:

• While this package is for 3d scenes, the fog of war logic acts on a 2d, "top down" (or with the 1.3 update, the forward X/Y or Z/Y) perspective. this means that line of sight is based off the revealers height, and cannot see up or down. This is partially a design choice so that revealers taller than sight blockers can see over them completely.
