View Full Version : How to use a Velocity Pass

09 September 2008, 05:56 AM
Hi all! I'm new to compositing, so I'd appreciate any/all help you guys could throw my way. I'm using 3D Studio and want to use the Velocity pass to apply motion blur in post rather than render it out. I had 2 questions regarding this:-

1) Whats the difference between Filtered and Unfiltered Velocity passes (its an option present in 3D Studios' Render Elements tab)?
2) How do I use/apply the Velocity pass in Combustion?

Thanx for all your input guys! :)

first read previous post before ,you may find answer about blur ,
to be clear render your job at rpf file and choose option velocity,finaly filtred or infiltred try and see the difference:p

Filter applies anti-aliasing to the velocity channel, unfilter renders without AA. Filtered can give smoother and better looking motion blur, but the results won't be accurate since color values will be combined anywhere AA is applied.
