how to do a long exposure render in Vray 1.5 Rhino 5

[kv1]

Hello,

I am attempting to do something similar to this:


How can I achieve this using vray and rhino?
I made it to here:
http://docs.mcneel.com/rhino/5/help/.../animation.htm
And here:
http://www.vray.com/vray_for_rhino/m...l_camera.shtml

It looks like there is a motion blur filter for the camera in vray. There is also the SetPathAnimation command in rhino. I assume by using both, I will be able to get a long exposure render?

I also have a set of emissive vray materials, which I assume will work under a low exposure. Then I would composite several samples in photoshop. How do I get the motion blur to work though? When I set the animation and record it, all I get is a multiple set of frames, not a single frame with motion blur.

Any help or guidance will be very much appreciated

I think the best approach would be to model long tubes with a self-illuminating material.

@Marc, thanks so much for your help! Still having trouble though; I posted my results in the mcneel thread.

I ended up modeling pipes with an emissive material like suggested. Worked great!
