This is a plugin for Unreal Engine Editor 4.14+.
It repairs static mesh assets that have been imported from FBX with Unreal Engine
in a way that results with a mismatch beween LOD Sections and Material IDs.
This importation bug has been fixed in 4.15, however already imported assets
remain unchanged.
The main donwside of
this bug
is that the drag n drop functionnality for Materials to Static Meshes is broken.
(The material is applied to the wrong section of the Mesh.)
Also, it breaks code that relies on equality between sections and elements.
Add this folder to the Plugins folder in your project directory.
If the folder doesn't exist, create it alongside Content.
Relauch the editor. A new button should show up on the main toolbar.
If not, check that the plugin is correctly selected in the plugins menu.
Select in the viewport the Static Meshes Actor you want to repair, the click on the button.
Info should appear on the debug log.
Modified assets will then be marked for save.
Once you've clicked, materials will appear mismatched in the viewport. This is just a visual
artefact and the best way to overcome it is to hit delete then undo (ctrl-Z). Alternatively,
you can save and close, then open the project again.
Feel free to report bugs and crashes, I'll look into them.
By design, this plugin takes materials that are defined on Meshes in the map and applies them to the mesh asset. If this is not what you want, I can change it. Just open an issue.
