Hi all,

I have a question in H13.
I try to copy an object to points of particles.
and scale this object with attribute of particles like AGE by stamping.
I attached simple test Hip file.
As you see particles have non zero value for AGE.
but stamping do not work well.

hope someone could give me some advice ?

Thanks,

takahiro )

Hi Takahiro,

You just found a bug.

It seems the attributes created by the new POPs is causing the Copy SOP's stamp function some confusion.

If I use the old POP Network and create particles, your example works right away.

If you need this to work in the meantime, you can reference age with a point() function in the Stamp SOP.

Please submit a bug report through the Support > Submit Bugs and RFEs link above.

Cheers!
steven

While this may be a bug, I would suggest using pscale on the particles to scale the geometry. You can create a pscale attribute using age on the particles themselves, and the copy sop will read pscale and use that as a multiplier when copying.

Or alternatively, you can pass age through as an attribute rather than a variable in the ‘attribute stamps’ field. Check out this example.
