This is the effect that appears when a hero has a new point to spend on the skills that the colors he uses are red, orange and yellow.
To make the model work when you import it to your map or campaign in the import manager, use a custom route and place: UI\Buttons\HeroLevel\HeroLevel.mdx
Ready, it will work for you and every time a hero has a point available, it will look great.
Give me credit if you use it on a map or campaign
