View Full Version : Poly points to FFD points?

I'm almost 100% sure this can be done.
I copied out the points from an FFD to a blank Polygon object. Now I just want to set up an Xpresso to make the Poly object points to drive the FFD object.

I assume you use a point node, but that's pretty much where I get stuck.

( I suppose it doens't have to be Xpresso driven. Just looking for the fastest way for the FFD to be driven by the Poly objects points.)

Thanks so much in advance!

Use points nodes on both your poly object and your ffd object, iterate through the points and use the poly objects points position output to drive your ffd objects points position input.

Thanks Per!

I got it react at least. To bad it was to Collapse all the points to one spot.

Any hints as to what I have wrong? (see attached)

You created a position input for the point node assigned to the cube, this lead to all the cube points beeing set to what you entered in that port, in this case very likely 0/0/0
If you don't create an input node the point node will only output data, just like you intended.

Thanks Srek! I didn't know unlinked ports could affect the output in XPresso, that might explain problems I've had in the past. Working perfectly now!

Unlinked input ports work like if a constant node is connected, so you don't have to create them.
