Advanced Rendering Features

This section describes important rendering options and tools that can significantly improve your application.

• Unreal Forward Shading Renderer (PC)
  Unreal Engine 4.14 introduced an experimental forward shading renderer optimized for VR. We recommend that all future PC titles use the forward shading renderer.
• VR Compositor Layers
  In some versions of Unreal, you may add transparent or opaque quadrilateral, cubemap, or cylindrical overlays to your level as compositor layers.
• Multi-View (Mobile)
  Multi-view is an advanced rendering feature for Gear VR, available in experimental form in Unreal 4.14 and later. If your application is CPU-bound, we strongly recommend using multi-view to improve performance.
• Hybrid Monoscopic Rendering
  Hybrid monoscopic rendering is an experimental feature introduced in Unreal 4.15 that renders objects close to the viewer in stereoscopic 3D, while rendering all objects that lie past a culling plane only once.
• Adaptive Pixel Density
  Adaptive Pixel Density allows applications to scale down the application viewport as GPU resources exceed 85% utilization, and to scale up as they become more available.
