Motion Blur Shutter Efficiency

[White Wizard]

I'm not seeing any difference with shutter efficiency set to 0.1 vs 1.0. I'm using the 3dsmax Physical Camera, rendering in Next GPU.

Perhaps I'm wrong in my understanding of the effect?

From what I could gather, lowering the shutter efficiency should shift the intensity of motion blur towards the midpoint of the blur, creating a more natural gradient at the beginning and end of the blur. Currently I have sparks moving across frame and the motion blur has a very harsh beginning and end, being completely uniform in intensity across the entire blur.

Hello,

Unfortunately the V-Ray for 3ds Max shutter efficiency setting is currently not supported in V-Ray GPU (or Chaos Cloud too). We've logged an issue about that in our system (VMAX-8930) and will post back when it is fixed. We'll also update the docs with that information.

Sorry for the inconvenience.

Best regards,
Yavor

Okay. Thank you for letting me know.
