Unreal Engine Integration

Unreal Engine powers many modern games, and Simplygon has extensive experience optimizing projects built on this platform. By using the Simplygon SDK, you can effectively address many common performance issues within Unreal Engine environments.

Simplygon offers a plugin for both Unreal Engine 5 (UE5) and Unreal Engine 4 (UE4), providing powerful automated optimization features out of the box:

• LOD Recipes: Define Level of Detail (LOD) chains for groups of skeletal and static meshes.
• Stand-in Outline: Optimize scenes non-destructively, ideal for kit-bashed assets, with the Stand-in Outline feature.
• HLOD Generation: Utilize Simplygon's remesher to create Hierarchical Level of Detail (HLOD) for distant areas in your game.

Advanced users can leverage the plugin’s blueprint library commandlets, and Python hooks to automate and customize optimization workflows. Additionally, the plugin’s source code is fully accessible, offering complete control over the optimization process.

Key features of the plugin include:

• Automatic creation of LOD meshes for skinned and static meshes.
• Draw call optimization through Material Merging and Object Aggregation.
• LOD mesh creation for hard surfaces and organic meshes using the Triangle Reducer.
• AAA character optimization, preserving skinning and blendshapes.
• Complex character rig optimization using skinning influence reduction.
• Decimation of large 3D scanned or sculpted meshes with the High-density Reducer.
• Vegetation asset optimization, such as trees and bushes, into simple boards.
• Creation of distant Flipbook impostors with an included shader.
• Overdraw removal from kit-bashed assets with aggregation using stand-ins.
• Low poly HLOD proxies or distant LOD meshes creation via Remesher.
• Triangle removal not seen from any camera angle in-game using visibility culling.
• Material flattening to support any Unreal Engine material.

Simplygon’s Unreal Engine plugin empowers technical artists to automate 3D asset optimization. Used extensively in AAA game productions, the plugin is continually improved through collaboration with developers worldwide.
