H13 new copy sop

[MENOZ]

from the doc:

Copy stamping now support stamping template attributes. You can also stamp string attributes.[/CODE]

what does it mean stamping template attributes? I don't understand what's the difference from before.

also

[CODE]There is an option on the Copy node to cache the input geometry during stamping. If a stamped instance has already been computing and is in the cache, it will be reused. Turn this option on if you expect many stamped instances to be similar to each other.[/CODE]

what does it means with similar? if each copy is just rotated randomly for example, does it works? what are the requisites for 2 copies of geometries to be considered similar? What if I just copy the geometry and i only change a Cd attribute? does it makes dinstiction between point poisition and other attributes?

EDIT:

my guess is that copy sop works with paked primitives as long as only the transforms are modified and nothing else. is it ok transforming the input geo with a transform sop then? this actually changes the P attribute. So I guess I should rely on Pscale, N, up attributes on template geometry to make it work properly.

thanks!

sorry if I continue to queue up questions but they are all related to these new features.

In this case I can't stamp correctly strings.

What i'm doing wrong in this hip file?

how can I stamp strings attributes?

I get correct results only if i stamp values to string unsing stamps.

if i try to stamp strings i get 0 or 1 values (maybe i get also other results but this is what i have so far)

thanks

that's why you now have handy parm Attribute stamps, you can simply list there attributes you want to stamp and then you will be able to access them through stamping

no custom variable creation needed so you can stamp strings as well

ahh wow, I didn't see that new attribute stamps at all yesterday..

thank you anim, very handy.

so problem 1 solved, what about the geometry packing and caching options?
