Reply To: Line Art modifier in Blender 4.2 issue

Hi Dmitry, here to help. I’m curious as to how you are adding this modifier? I have come across this issue before, but there are alot of settings which could ignore backface culling, for example. It also helps to have an active camera in your scene, as the line-art is determined on a camera to project what is seen and what is occluded.

My recommendation would be to delete that grease pencil object altogether and start over like this:

Is your group of objects in a collection? Or are these the only objects in a scene? Shift-A to bring up your Add menu. Choose “Grease Pencil Object” and select either Scene Line Art, Collection Line Art, or Object Line Art (these can be changed later, so don’t worry too much, but try and choose the option that best suits your needs).

This will generate a new Grease Pencil Object called “Line Art” with a new Black stroke material and a single Layer called “Lines”

Thew type you chose will determine the Source Type in the Line Art modifier – you can switch this to another Source Type here. It will determine which layer you’re influencing, and which material you are using. All lines should only show what is facing the active camera.

Try going through these steps and let me know if the issue persists?
