Yes, there seems to be a little discrepancy.
Can you make a bug report on github so I don't forget?
Just include the images and the test scene.

Re: first steps on luxcore
The Cycles motion blur looks very wrong, are you sure it isn't using a some fake approximation ?
Re: first steps on luxcore
Done thanks you

here is the cycles Motion blur panel. but don't really know how they have implemented this inside the core.
but they recently get a huge boost in DOF AND MB: here you have more info about :

Re: first steps on luxcore
Like I said the Cycles motion blur look wrong, there is barely any highlight motion blur. Are you using a not linear shutter curve ?
Re: first steps on luxcore
no shutter curve like in the panel i've uploadedAre you using a not linear shutter curve ?
Re: first steps on luxcore
I've maybe found a bug here : my lake shader don't want to render in viewport (giving a matrix invert error output) and appear matte at final render. Blend attached :

Re: first steps on luxcore
The Z scale of object "Plane.027" is set to 0.
If you change it to 1, it exports correctly.
Not sure how we should handle cases like this.

- We could add a small epsilon to all values of the transformation matrix if determinant == 0 (when the matrix is non-invertible)
- Or we could provide a better warning/error message
Re: first steps on luxcore
The first option is more user friendly !
Re: first steps on luxcore
Well, I kind of implemented both now.
You get a warning, but the object is exported regardless.

Luxcore Vs Cycles:
Both render under 1mn. same lighting condition. you will also notice that luxcore become darker and noisy when smoke volume is rendered while the lighting stay unchanged.
