Motion Vector Pass
Posted 24 February 2010 - 12:36 AM
I would like to know how to create a motion vector pass with houdini. I found two forum topics and this shader (http://www.sidefx.co...8&versionid=608) on the net they didn't work for me. Could someone please explain me how to create a motion vector shader/pass? That would be great, all the other passes work fine.
Thanks a lot!

Note the "allow image motion blur" parm that i added to the mantra rop and turned off so that the output isn't blurred.
I dunno how much you know about shading so ask if anything doesn't make sense!

Attached an example using a basic surface and exporting a pass set ...

Can you show how to use the same setup but on the geometry level? I've tried using your setup and realized that if I have anything animated on the geometry level, the vector pass doesn't work.

(You can also add Geo Time Samples to a single object if you don't want it as a global setting, add the setting to your object with the gear icon > edit rendering parameters)
