AutoDecalMerger Plugin is very useful for adding up certain gore level for your top down game, or for similar concepts.

The Plugin merges overlapping Vertically Projected Decals (spawned by DecalManagerComponent) thus reducing pixel overdraw to as low as possible.

 

This allows you to have hundreds of translucent Decals in a dense area, the denser the area the more decals you can merge.

 

The heavy processing is done on a background thread, allowing as less performance impact on the game thread as possible.

 

*Note: The merging is done by approximation of the material's textures thus having some error level.

*Note2: Therefore the plugin is not intended to be used with close-ups.

 

AutoDecalMerger Plugin is a great tool for creating great games.

Technical Details

Example project (4.17): https://drive.google.com/open?id=0B0IdKcPdt9ldX3l6d1NFeWYxN1U

 

Use DecalManagerComponent to spawn decals. DecalManagerComponent utilizes an adjustable background thread that merges decals without stalling the main thread.

 

*Note: AutoDecalMerger Plugin does not merges every deferred decals spawned in the level, it merges only decals spawned by DecalManagerComponent.

 

Texture requirements:

  • Compression settings must be VectorDisplacementmap (RGBA8)
  • Mip Gen settings must be NoMipmaps
  • sRGB gamma correction must be turned off.
  • Never Stream option must be turned ON.

 

Material requirements:

  • Material must have a texture parameter named "Texture" !
  • The sampler type of the texture parameter must be "Linear Color".

*Note: The more complex the material is, the bigger the error level will be. The plugin accounts only the texture itself.
