How can I use a spritesheet with a normal map in a flipbook?

I am using texture packer and sprite illuminator to create my sprite sheets. I imported them fine as an unreal file, but when the textures are not using the normal maps. Is it possible to use the normal maps in a flip book? Thanks

Here’s what you need to do:

You need to set your sprite’s material to DefaultLitSpriteMaterial. This material has a parameter for Normal Maps but you need to “activate” it before you can use it.

See the space for a texture below “Additional Textures” ?
This is where you will be adding your normal map.
Click on the + button to add another element.
When you see Slot #0, select your normal map and set it.

You must do this for every sprite individually, as this UI option does NOT appear in the Flipbook Editor.

If you want to do more than just add normal maps, make a copy of DefaultLitSpriteMaterial and then add metallic or roughness maps copy and pasting the same way the normal map was added.
