" 1. Begin the import process by using one of the methods listed above.
2. This opens the Interchange Pipeline Configuration window."
“methods listed above” are the ones listed in " For more information on importing files, see Importing Assets Directly." While these traditional importing methods do not invoke Interchange Pipeline Configuration window.
You are importing through editor? No automation through scripting?
The Interchange Dialog window should popup if you drag and drop asset in content folder, or if you do the right-click import or the import in content folder menu.
Which format are your trying to import?
Interchange import dialog can be hidden in the settings. By default for textures files UE does not show the import dialog. That can be re-enabled if needed.
You can type the following console command
Interchange.FeatureFlags.Import.FBX true
But keep in mind this feature is still considered experimental in 5.3.
Especially I would avoid “import into level” of FBX, Interchange import is still missing many features for that use case.
No worry, I’m not in a project, I was just looking for “local lights buffer” (no info found) and I found Local Light is under “Interchange”, and was curious about it
