When using the Make Material Attributes and landscape layer blends, if an Emissive input is being utilized on any one layer, the other layers must also utilize the emissive input in order for it to render correctly.

Steps to Reproduce

1. Open attached project.
2. Open the M_Landscape material.
3. Disconnect the Emissive Constant pin for the Layer Grass material attributes.
4. Apply and Save.

Outcome The previously visible emissive texture on the second layer is no longer visible.

Expected The layer renders as expected without the need for a constant to be used on the other existing material attribute layers.
