Optimize with Custom Data | 5-Minute Materials [UE4/UE5]

Hey hey! Today we're talking about Custom Data, or Custom Primitive Data which is an extremely awesome way to create variation in your assets, as well as a very effective way of optimizing your scene. Draw calls can be a huge performance bottleneck if left unchecked, but Custom Data allows us to have control over colours and other parameters in materials without breaking instancing or creating many material instances.

Enjoy!
