Tutorial 12. Copy Stamping and the Foreach Loop

This tutorial describes how to use point attributes to influence upstream input nodes:
- first using the traditional Copy Stamp Node (at 01:30 minutes)
- then again using the Foreach Loop nodes as recommended by sidefx (at 15:35 minutes)
Then it takes an in depth look at the other uses of a Foreach loop:
- Looping groups of points based on an attribute (at 38:17 minutes)
- Looping through connected pieces (at 45:30 minutes)
- Looping a set number of times (at 57:25 minutes)
- Creating fractals (at 64:50 minutes)

I've been having a terrible time trying to understand for loops, this is making things a lot easier, thank you!

[@KZLR]

Great tutorial, and you have a lovely voice for teaching.

Video was great explained for loops much better, I have been having issues exporting my for each loops to alembics, the rop alembics node gives me a bunch of renaming errors which is an issue because each instance exports as a single mesh rather than one single alembic object regardless of what i do or whatever path hiearchy i have set. is there a node or something i should put after the for each loop to mitigate this? any information would be appreciated thank you!

Can you show us how you created the tree hda ? You say that you're using the hda that you created in the first tutorial, but you didnt create it there, you just imported it and used it.
I tried to reverse engineer it, but I couldnt quite figure out the relative references used in the attribute vop.

Susie goes over how to make the trees in the volumes and VDBs episode.

I think the reason you were getting the too many instances of tree #4 at (37 min) Is because you were fitting the random values between 0 and 5 and not 0 to 4. So the last tree variation was getting an extra chance of being chosen.

Good to know, that's the kinda thing i would do, and not realise at all. Syntax, its my downfall. Did i read somewhere you can compile this node (for each) and if som would that speed up the sequential process, without having to do what's looks to be a long winded work around of the sequential stepping through all the trees point numbers (well, seed numbers to be exact).

oh for loop is 1000 times faster than stamping.... thanks
