How to use VrayVelocity with realsmart MB pro 3.2 and AFX

[stilgarna]

Hello guys,

i d'ont underdstand the way to use Velocity pass with realmart motion blur pro 3.2...
I'm using Vray 1.5Rc2 with Max 8 and After Effect CS3

Do I use RSMB vectors ?

Does the VrayVelocity works with RSMB ???

Do I miss something ???

I don't know... I'm going crazy... Can someone help me please !!!!!


Best regards...

import rgb's and vel. in ae set vel. to invisible and say Reelsmart MB "get motion from" vel. layer.

but doesn't work too good imo...

I think vrays velocity outputs a motion vector read by nuke. It is not a motion vector which is accepted by RSMB.

Aoutch... bad news...

indeed. I hope this will be implemented. For now, if you dont have a complex scene, ie vray proxies, displacements, you can generate the correct MV from mr and use those.

I hope too...

But how to make a MV with mr ( La maison shader ???)... and when you use vrayphysical cam... ???


Are you working with AFX at Zoic ?

we are not. But RSMB is ported to many comp packedges, shake, combustion etc...
If you are using physical cam, unless you are using some special settings, I think you can reproduce it with usual camera and render that.

thats why it havn't worked well....

The velocity channel output by V-Ray was designed to be as close to the one output by the scanline renderer. I wouldn't know how that relates to RSMB though; I suppose I'll have to take a look at it.

So this worked fine in my quick two tests that I did; see this thread for more explanations:

I think vrays velocity outputs a motion vector read by nuke. It is not a motion vector which is accepted by RSMB.

On the contrary, it looks to work fine... again, see the thread in the link above.
