In Unreal Engine 5.4, to ensure that TSR (Temporal Super Resolution) does not add motion blur to your Spine sprite, you need to adjust the material settings used by the Spine renderer. The material you should be looking at is the one assigned to the SpineSkeletonRenderer component.
Here are the steps to follow:
Identify the Material: Ensure you are using the correct material that comes with the spine-ue4 package. This material is typically assigned to the SpineSkeletonRenderer component in your UE5 project.
Adjust Material Settings: Open the material in the Material Editor and look for the settings related to motion blur and pixel animation. You need to ensure that the "Has Pixel Animation" option is enabled. Additionally, make sure that Anti-Aliasing (AA) and Output Velocity are properly configured.
Check for Premultiplied Alpha: If you are experiencing issues with blending or transparency, ensure that your texture atlas is exported with the correct alpha settings. UE4/5 generally requires non-premultiplied alpha for proper rendering.
Post-Processing Effects: If you are using any post-processing effects, ensure they are compatible with the material settings and do not introduce unwanted artifacts like motion blur.
For more detailed adjustments, you might need to refer to the specific documentation or settings within the Unreal Engine related to materials and post-processing.
