[Request] Import custom vertex normals

It’s a common trick I use to change the way light affects a cutout plane, like grass or fur, by manually adjusting the direction of the vertex normal. In UE3 this was impossible, as the vertex normal data is recalculated on import. Is there a way for us to preserve this data. Benefits to this include artistic control over how the light falls on a plane and how material level world offsets are applied.

You can already import custom vertex normals for static and skeletal meshes. In the import dialog, change the normal import method to either “import normals” or “Import normals and tangets”.

Hi Jason,

Thank you for your request. I have created a report and entered it into our feedback database. If there is anything else that you would like to see in the editor, please let us know.
