I'm using an Instancer LOP (method Point Instancer) to animate a missile in Solaris. I have a "v" attribute on the points that get correctly translated to a "velocities" array. How can I copy it to the instanced object? I'm trying to create motion blur.

Can you share an example hip that demonstrates how far you've gotten and where you're stuck?

While creating a demo hip to show this, I found out that it works if I'm setting "Location Source" to "External SOP". Before, I had it on "First Input's Points" and loaded the animated point using a SOP Import.

Ah, yes we do not currently copy attributes from *USD* source points, only from *SOPs* source points. There is an open RFE for this.
