Thank you for using Amplify Motion, we really appreciate it. Correctly representing motion blur on fast rotating objects such wheels or propellers can be quite troublesome, we usually recommend excluding them all together and using an alternative dedicated shader effect.
Based on the screenshot it seems that AM might not be properly setup, the wheels should definitely not look like that. Did you add the Amplify Motion Obj Script to the parent object GR500? Both chassis/body, wheels, or any additional parts, should have the AM object at runtime.
We've got a way better result now : (althought motion scale is really too high ! )
anyway, still got problem in "Photo mode". ( we set timescale=0 for this). motion blur seems not update when we rotate the camera : ( any idea how we can fix this ? )
we've also think about a shader. do you have one in mind ? (assetstore,...)
Our apologies for delayed reply. Unfortunately it wont be possible to support a "Photo Mode" using the Timescale value to freeze the scene, we cannot properly access the required information when it's set to 0.
