Hey Guys, It’s weird - i just can’t get proper motion blur alignment with the mr prim method. Setting the motion blur start interval for the Hair to: “start” produces the best result but it’s still plain wrong (check frame 11) Am I doing something wrong?

perhaps you need subframe motion blur geo sampling? trys setting it to 4-6

[image]Problem With rectangular light effect on renderings perhaps you need subframe motion blur geo sampling? trys setting it to 4-6 Nope, that doesn’t work either. going from two to three samples (with wich the image is renderred) helps a bit but no change above that.

Ok, setting the motion blur interval of vray to 0,25 solved the problem - it seems hair & fur has odd settings for the motion blur (it was set to “beginning”)

Duration and position of the motion blur interval for the Hair&Fur effect are controlled from the Hair&Fur render effect, rather than from the respective V-Ray settings. This is mentioned here: Chaos Docs
