Provided it is set to a value greater than 0. This means that when this Shading Model is selected in the Material Editor that material will write either the value of the CustomData0.x channel, when exposed by the Shading Model, or the value of the console-variable r. Materials that use this Shading Model will be treated as reactive. Option in the FSR2 section of the project settings or using the r.Ĭonsole variable. This can be reduced by ensuring such materials write into the Reactive Mask generated in the plugin.įor the Deferred Renderer this can be achieved by selecting a Shading Model for the Reactive Shading Model Animated opaque materialsĪnimated opaque materials which don’t generate motion vectors for the animated content, such as in-world video screens, may also blur or ghost when obscured by static geometry. If it is necessary r.Velocity.ForceOutputĬan be used to force all primitives to emit velocity. In this version the default is to render velocity in the base pass and this can be changed using r.VelocityOutputPass
Unreal 5.1įor Unreal 5.1 the handling of WPO has changed and more objects with WPO should render velocity by default. When changing the content grass layers attached to Landscape actors require a new console variable r.īe enabled, this will change their mobility to Stationary so they render motion vectors. Which renders velocity for all objects during the base-pass.įor cases where this is too expensive and changing content is infeasible follow the installation instructions to install the correct version of the ‘ImproveStaticWPO’ engine patch to avoid this issue or ensure that all objects using a WPO material are set to Stationary or Movable. Then disable the console variable r.SelectiveBasePassOutputs One option is to enable the console-variables r.BasePassOutputsVelocity
This affects FSR2’s ability to correctly upscale such materials and results in blurring/ghosting of the affected objects. Static objects that use a material with World-Position-Offset do not generate motion vectors. The pre-built binary version of the 5.1 plugin requires Unreal Engine 5.1.1 due to an ABI incompatibility between 5.1.0 and 5.1.1.
