Getting At Cd[0,1,2]

[kai.scorpio]

I'm trying to make a copy/stamp with the color of the boxes to be stamped based on the color of the template points. So I created a copy node with 3 stamp attributes, RED, GREEN, BLUE, set to point("../point1", $PT, "???",0). what would I have to put instead of the ??? to get only the red, green or blue value of Cd (Cd[0], Cd[1], and Cd[2]).

If this is not enough to go on I can post the .hip file later.

The last argument of the point expression is the attribute index, so all you need to do is put in point("../point1", $PT, "Cd", #) to the 3 fields, replacing # with 0 for red, 1 for green and 2 for blue.

you are just about there. RED would be point("../point1", $PT, "Cd",0), GREEN would be point("../point1", $PT, "Cd",1), BLUE would be point("../point1", $PT, "Cd",2). the last field represnts what index of the attribute, in this case Cd, you want to access. so 0 is RED, 1 is BLUE, and 2 is GREEN.

Ah, beat me to it...yeah, do what Hammy said.

Wow replies already... thanks a lot! I thought the last value was what is put if nothing is found, like with stamp().
