So I have been running into an issue where I am wanting to delete polygons from a terrain that are outside of my camera frustum. But, the points that are included inside the group are correct on one side but incorrect on the other side. There seem to be points in the group that are not even inside the bounding object.

I have attached a photo to show this.

Does anyone have an idea why this is happening?

how exactly are you grouping the points? can you share your hip file?

Ah, so I think I figured out the issue. On the geometry representing my camera frustum, I had a really large value for the distance it was projecting out. So I lowered it and everything grouped correctly. Don't know why that is though.
