Sorry that I didn't check, Dade.
It still looks wrong on my end.
This is with shutter = 0.5, both green sphere and camera moving at same speed, background stationary: But it's also weird that when only object motion blur is enabled (no camera motion blur), the result is different from Cycles.
Maybe I'm doing something wrong in the addon.

Spawned a dedicated thread.

Here's the BlendLuxCore issue: https://github.com/LuxCoreRender/BlendLuxCore/issues/16
There are also other weird things going on, like that the object seems to travel further than it's start and end points with long shutter values.

I think I'll write some unit tests, maybe that will help me sort it out.

Uhuh, the problem is in Embree when using negative time values. If you use PATHOCL it works fine. This explain some of the confusion and why it was working for me and not for you.

I'm checking if it is a bug in LuxCore Embree-related code or in Embree (or is the expected Embree behavior).

Some bug is incredible: https://github.com/LuxCoreRender/LuxCor ... eef0d22d5d

The Embree-related code was always using time between 0.0 and 1.0 because of a Min() swapped with a Max().

Now everything is working fine here.

I was in the area so I added the support for Embree multi-segment motion blur

I had a good laugh at this log:
"Let's make an issue, but don't do it right now because it's probably complicated"
"Wait - it's actually really simple"
"Done."

It took about 1 minutes

BTW, a couple of days to let the things settle down and I guess we can release alpha2

Yes.
I'll try to fix a bug where particle and hair systems on hidden layers are exported before we release alpha2.
