Hi,
got an issue where LineArt doesn’t draw on all objects of a linked *blend file Collection.
The modelled object is a house. LineArt in the model’s *blend file works fine.
But the moment I link the model’s Collection into a fresh *blend file, the LineArt goes crazy. The roof still receives LineArt, while the Walls + Windows are lacking a lot of it.
The Walls + Windows are made from GeometryNodes. The roof is not. This is the only difference I can see.
How to get my proper LineArt back for the linked objects?
Converting the GeometryNodes to a Mesh worked.
So first, before the last GeoNode, add a “Realize Instances” Node. Normals might look awkward now. Then, in the 3D Viewport, click “Object>>Convert>>Mesh” to convert it to a mesh. Normals are still awkward.
Then, you can decide yourself on the Normals again. For example RightClick and choose “Shade Auto Smooth”.
