Vray motion blur problem

[larex]

I realy dont know but it worked. I also tryed the scanline renderer but it has sometime some bugs like collorfull splotches in motion blured image.. And also when we are using plugin like vray scatter we cant render image with holdouts because it is not working with scanline. Can you please solve this issue and len the vray render exact same image like scanline is with motion blur effect?

Thanks
