Simple Spin Blur is a Visual Effect based on the Video/Optical Feedback Motion Blur Technique

Check out the WebGL Demo on our website in the Try It Out section.

Highlight the main spinning/swinging object with a simple lightweight motion effect to increase the visual quality of your game.

Available in both HDRP and URP!

Main Features :

- Single object Motion Blur - Affects only the object the script is attached to

- Accurate Materials and Lighting - Normals, displacement, and metallic maps are preserved

- Compatible with any Shader - Normally, transparent render queues work best, but this blur techinique supports any shader that is present on the object.

- Volumetric Blur - The object is blurred in 3D and not just a 2D image effect

- GPU Instanced & Accerlated- Multiple meshes are rendered on the GPU for maximum performance

- CPU optimization - Uses native linear data structures to increase performance

- Motion sensing and cutoff - Designed to be as efficient as possible, the script cuts off motion blur if there is little to no angular rotation

- Any Trajectory - Works with any motion trajectory

- Submeshing - Ability to render motion blur on parts of a mesh if the mesh has different materials on it

This technique mitigates the artifacts caused by linear motion vectors on rotating objects. Works by interpolating samples between two quaternions with transparent meshes.
