but when I need to writes these values to each point, I cannot ? (the index value of the for begin outputs a constant instead of (0,1,2,3…)

Hey there Probiner, did you manage to get the indices back from an array ?
How comes when I do this loop, it does takes the index of the loop and fills the array with it.

I found a solution.
If you are a super noob (as I am), I attached a picture to explain.

Hi there,
I'm doing a water jet using Flip and I'd like my particles to “die” after a few seconds.
How should I do that ?
I found an @life attribute in wrangle (Pop_Wrangle), but I'm not sure how to use it.
Is there a simple exemple somewhere ?
Thank you !

Hi Eetu. Yes, in polyframe I tried it, I can set a N and (tangent)up Vectors.
But I'm not sure of the result for the up.
Hi Sanostol. Can you elaborate on the Vex method ? could you share the syntax? I'm bold with Vex, is it possible to build it in VopSop as well ? I'm specialy interested in that orientation you describe.
Thank's a lot for your help guys

Hi Mandrake and thank you.
Yes, I'm aware of this thread @Odforce, but it's only about placing the object at the center of each poly, which I think I already got well.
Though, the convert to circle seems to do some magic.
I'm looking for a good way to orient the object localy per polygon.
I've watched Kim Goossen's tut, I'm ok with normals. The “up” part is interesting as it shows what Houdini expects. For an “overal” up looking at Y (0,1,0) it's ok. But a bit like what he shows with the Comb technique, I'm looking for some Per Polygon orientation.
In xsi we have PolyReference frame, I believe it outputs a Matrix or something convertible to an orientation, and it's per Polygon.
Thank you !

Hi gang,
Slowly getting to houdini here, and I have a dumb question that might have a simple answer.
I'm trying to do a copy of an object (cube) onto another object (torus), but instead of copying per point, I'd like to copy per primitive (polygon).
So that in the end I have one little cube centered on each polygon of the torus.
While I'm able to position each cube centered onto each polygon, I'm having serious difficulties having them well oriented to their corresponding polygon.
I can have the cube oriented with the normal, that works “okay”, but I still need some kind of up vector to have a local orientation.
If someone can point me to the right direction, or to a tutorial that would be awesome
Thank's
