Motion blur for rotating objects

AiKodex released Simple Spin Blur for Unity 2020.3.14 and later. The script adds motion blur to rotating characters and objects, with single-object and volumetric modes, support for arbitrary trajectories, submeshing and motion cutoff.

The implementation was described as GPU-instanced and CPU-optimised, with compatibility across shaders and support for material and lighting response.

Shader requirement

The shader needed to use an Alpha Test or Transparent queue because the script modifies alpha to create transparency. Standard shaders worked best in Transparent or Fade mode. Verify current render-pipeline support before production use.
