- DataTable CSV export
Unreal Engine essentials
The details that trip up most developers, and that every tool on this site handles for you.
Normal maps
Unreal expects DirectX normal maps (green channel points down). Use "Flip Green Channel" in the texture editor for OpenGL maps.
Packed textures
The ORM layout puts Ambient Occlusion, Roughness and Metallic in R, G and B. Use the "Masks (no sRGB)" compression setting.
Units & axes
Unreal is Z-up and X-forward, and 1 unit is 1 centimeter. Rotations use FRotator(Pitch, Yaw, Roll).
Texture sizes
Power-of-two textures can be mipmapped and streamed, which keeps memory predictable.
Data
DataTables import straight from CSV, which makes balancing data like XP curves easy to iterate on.
Selling
Unreal plugins and assets are sold on Fab, Epic's official marketplace.
