Changing material on mesh, Play Montage of MorphTarget, material turns grey

Character material changed by picking up a powerup. Set material node in Blueprint.

Then on firing a projectile, a montage is played on the character. THe Animation is a morph target. Not sure if that’s the right name for it.

The montage plays but turns the material to grey, like it knocks it off the mesh.

you’d need to show the blueprints etc you are using.
Without any information we cannot help you.

I’ll put up a pic of the bp tonight. It’s just the set material node and selects the material from it’s drop down. It works, but then when I fire the material turns to grey, there’s nothing to do with the material in firing.

I renamed the question and changed the description. It’s playing a montage of a morph target after the material has been changed that causes the issue.

Opening the material in the Editor, in Details in the Section Usage there are check boxes.

Check Used with Morph Targets should be checked.

This fixes it.
