The asset browser
Find, filter and drag media and saved subgraphs into the graph.
The browser lists what has been found in your asset folders, the subgraphs and graphs saved in your library, the files the nodes in the current graph already point at, and anything you linked with Import.
Browsing and filtering
Search filters the grid by name. Hold Cmd and scroll, or pinch, to change thumbnail size; past a point the grid collapses into a compact list of icons and names. Plain scrolling scrolls.
The sidebar is a type filter rather than a folder tree: All Assets, then Images, Videos, Audio, 3D Models, Subgraphs and Plugins, each with a count and each shown only when it holds something. It can be resized to give a long list more room. Below the filters, Import links files where they sit without copying them, and + Add Folder registers another folder to scan.
Only images get a real picture, and only the first 32 of them. Everything else shows a type icon.
Selecting
Click a row to select it, Shift-click for a range, Cmd-click to toggle one. Right-click gives Delete and Deselect, and Delete or Backspace does the same as the first. Only subgraphs and graphs held in the library can be deleted this way; files on disk are left alone.
Drag to create
The browser drops into the The node graph and the viewport, and nowhere else. The node kind follows the file type, so an image becomes an image node and a model becomes a 3D node. A .ply file is read as a splat rather than a mesh. See Importing media.
A node dragged out of the browser arrives with no file attached. You get an empty node of the right kind and have to set its path yourself. Dragging the same file in from Finder does bind it, and dropping onto a socket does nothing at all.
When an asset can't be found
A file that goes missing does not stop the graph loading. A missing image renders as a magenta-and-black checker placeholder and is listed in the Missing Assets panel, with its path shortened to $PROJECT/… when it sits inside the project. Each row offers Retry, which re-imports from the same path, Reveal, which opens the containing folder, and Copy, which copies the path to the clipboard. There is no relink button: to point a reference somewhere new, edit the node's own path.
Only images are tracked this way. Video, 3D models and splats still load through an older path-based route, so a missing one of those never reaches the panel.
