Small guide on exporting the textures mesh from Substance Painter into UE traditional "packed textures", where the exported files are base color, ORM, normal and emissive (optional).
- File -> Export Textures
- Click
Global settings
and pickUnreal Engine 4 (Packed)
forOutput template
.
You can manually decide which textures you want to export for each mesh part.
Once you click Export
it will generate all the textures for the mesh, and they will be ready to import into UE4/5 and game-ready.
That's a straight forward process of dragging in all the textures, creating a material and connecting everything up in the material graph, as shown below.
Important
Make sure the ORM/packed texture is set to Masks in Compression Settings within the texture, and Normal for the Normal map.
If you have the emissive texture for your mesh, you can adjust its strength and color by multiplying it by the color and then by a constant for its strength.
