Honokaitj 0 Posted March 9 I'm having trouble figuring out the best way to achieve something. I'm creating a wall of bricks. Each brick will later be replaced by a far more detailed brick. I'm trying to keep my scene as light and memory efficient as possible so I'm using copy to points and pack and instance is checked. However, I need to cut a hole into this wall. In my example it is a tube, but I'd like to figure out how to do this with any shape. What I want to do is figure out how to do one of two things. 1. Prior to copy to points create a group of the points which will later have bricks that need unpacked in order to boolean. 2. After copy to points with pack and instance create a group of packed bricks that will need to be unpacked in order to do a boolean. If you look at the image I've provided you'll see some points are outside of the tube shape, but would still need to be part of the group that gets/remains unpacked. At the same time some are mostly or completely inside the tube and would also need to be unpacked. I know I can just use a peak node on my tube to make it wider just for selecting, but I'm wondering if there is a more elegant way of doing this. I was thinking of something like intersection analysis, but that isn't the right thing. Is there a way to determine if a packed/instanced brick is partially inside the tube geo?

Skybar 352 Posted March 10 Hey! You could compare the bounding boxes, and unpack only those that overlap. Here are 2 similar methods for that Hope it helps! unpackbbox_dv.hip 1 Share this post Link to post Share on other sites
