Add Glitter Shader to an Existing Material by Merging Material Attributes
1. Open the material Content/LevelPrototyping/Materials/M_Solid.

2. Right click anywhere on the grid and create a Material Function Call node.

3. With the new node selected, in the Details panel, select the material function MF_Glitter_MergeGlitter.

4. While holding CTRL:
-
Drag Base Color from the material’s output and put it into MF_Glitter_MergeGlitter input Existing Material’s Base Color.
-
Drag Metallic from the material’s output and put it into MF_Glitter_MergeGlitter input Existing Material’s Metallic.
-
Drag Roughness from the material’s output and put it into MF_Glitter_MergeGlitter input Existing Material’s Roughness.

5. Reorganize the nodes so that the material function is between the parameters and the material’s output.

6. Connect the material function’s outputs to the material output node's corresponding attributes.
-
NOTE: Do not connect WPO ONLY for Overlay Material. This is for Overlay Materials only.

7. Click Apply and Save.
