Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 551.86

Blender Version
Broken: version: 4.1.1, branch: blender-v4.1-release, commit date: 2024-04-15 15:11, hash: e1743a0317bc
Worked: (newest version of Blender that worked as expected)

Short description of error
The "Intersections" check box in the Line Art modifier for Grease Pencil adds lines at intersections involving objects outside of it's set collection.

Exact steps for others to reproduce the error
Create two collections. Both has a set of intersection objects. Assign a grease pencil Line Art Collection to each. Check on "intersections" in one of the line art modifiers, and notice how it affects the other objects as well.
Alternatively, use the provided .blend file, toggle on and off the grease pencil object labelled "Intersections".

Hi! thanks for reporting. I consider this the same issue as #104562. And unfortunately it's currently a design limitation of line art filtering system.

Line art are only able to filter intersections by collection with collection intersection bits. You can see more details here on the manual. Thanks!

Will close as a duplicate.

I found that exact post, but I didn't think it was exactly the same, but thank you. I'm glad this is a known issue rather than a sudden, mysterious problem only I have. "Known" means it might get fixes one day, with all the pushing for grease pencil tech.
