clip sop wont split geo properly

[rich_lord]

Im having alot of trouble with the clip SOP.

When I apply it within a for each sop, it isn't properly splitting up the primitives. Huge primitives get created, rather than lots of small ones.

I made a hip file to demonstrate the problem. It uses the clip SOP to split a grid into pieces inside a foreach. Then it puts one primitive inside a group per frame, so you can move the timeline forward and see the shape of the primitives it generates.

I see in a peter Quint tutorial that this technique works for him, but I cant see any difference in how he is implementing it and how I am.

Any ideas?

Thanks!

You're cutting initial grid every time and merge it. But you need to cut geo from last loop. I changed each sop (actually added mine) so that every new turn clip SOP gets geo from last iteration.

Thats great bloomendale - really helps me understand the foreach. I was misunderstanding the feedback and the Merge Results flag on the foreach node.

Thank you!

Just turn off the merge results option on foreach sop

Thanks Sadhu - I noticed that the feedback checkbox was connected to this via an expression. Got it working now.

The ForEach is a bit of a tricky fellow.
