Motion blur behavior

Hi everybody. I need help with motion blur.
As you can see in the attachment, light trail isn't perfect. I think it's subdivided by time steps (i use 32).
I can't see any options that make any objects trail perfectly smooth and I don't know if it's my fault or some motion blur limits.
Another question. What's more real? After, centered or before? For me it's centered
Thx for your help

Hi,
in short, it is a matter of speed, if you decrease the speed of the sphere by half, the issue is not visible:

A Good question from the topic starter.
And what to do if we need that exact speed and a long light streak in the frame?
I guess this is the engine's limitation?

It's not casual limitation. Developers don't want to have more than 32 time steps cuz they consider thus quantity enough for most of the scenes. I hope it's not the same idea for caustics depth in photon tracing

I have tested with 100 steps, nothing changed. It's a different issue I believe

But how if 32 is the maximum allowed in C4D plugin?

Because there are certain things that Ahmet can do in code to test various situations...

Yes as a developer I can do any testin.

Ok. I hope you'll can find the solution.
