Bind stamp in to VOPnoise

[andrejklimov]

Hello all,

I'm modeling some tentacle creature and ran into a problem. I don't know how to stamp attribute into the VOP sop and use it to drive turbulent noise to randomise shapes for every copied tentacle. Then i want to copy that tactically geometry again and randomise tentacle shape and/or animation.

I have tried to just bind stamp("../../copy" , "id", 0) into the vop and connect it to Offset of the Noise, but for some reason, Houdini just stuck in the loop.

Please see .hip below. I feel like it is something obvious, but I cant see it. Please advice

Just apply the noise after the copy, that should give you a random noise for each shape.

Thank you Hernan, your approach works fine, but just out of curiosity do you know how to do it by Stamping attribute into the VOP. I remember it from one of the tutorials which I can't find right now.

Stamping is now obsolete, and the new method is to use "for each loop" for varying copys. http://www.sidefx.com/docs/houdini/copy/tutorial_stamping.html

Thank you for the link Thomas.

Based on the description it is exactly what I would like to do, but how do i bring "point("../foreach_begin2", 0, "id", 0)" function into VOP to control my noise?

If you promote whichever vop parameter your trying to copy stamp, then outside the vop, the parameter will become available and you can place your copy stamp function into it

Hello Chris ,

Thank you for joining the brain teaser. Could you check out my .hip file? What I would like to do is to randomize my Turbulent noise inside the pointVOP with the point attribute from the other side of the copy sop "id".

Hey Andrej,

Take a look at what ive done, think it was what you were after (added a small sticky note with what I added/did also)

Thomas and Chris, thank you for your input. Now I understand what I have missed in Stamp solution. The for-each approach is a bit new to me, but it looks promising.  I will play around with both and choose the best one for the job.
