how do I create motion vector AOV while not affecting the result of beauty render

[Anonymous]

I checked ignore motion blur and of course turned on motion blur in arnold renderer settings. But when i check the motion vector layer it shows totally black in the arnold render window. Thank you.

It's in the docs: https://docs.arnoldrenderer.com/x/6gtkAg

Is the only way to pull a Motion Vector AOV using a shader in 3Ds Max?

'we must enable Instantaneous Shutter in the Motion Blur settings' doesn't exist in 3ds (that I can see). I can't work this out either?

Thanks.

@Alex Scott Please ask a new question next time.

You may need to update your MAXtoA.

Thank you! I'll do that now! (and will be careful about which thread I post to) - many thanks.
