Hi,
I'm trying to set up a Pref pass for a simple animated object in houdini/arnold. Im generally a maya user & its as simple as making a texture ref copy of the aniamted object & turning on the pref AOV there, seems not as straight forward in houdini .
any help greatly appreciated
Chris
Did you see the bottom of this page?

The Pref that this creates has 0, 8, or 16 channels ( depending on the Rest node settings, default creates nothing ), where for example P has x,y & z, this has Pref[0] through Pref [15], and every value is 0.0 except for the first and every 4th channel, which is 1.0. Even if I could figure out how to convert this into a vector or float, everything in the aov would just be solid red.
It appears that the Pref value is the *same* as the rest value - ? Unchanged? If that's the case, then all I need to do is get that rendered into rgb, which is pretty straightforward
