I am unable to reproduce this issue on our end. I have a few questions for you that will help narrow down what issue it is that you are experiencing.
- Can you reproduce this issue in a clean project?
- If so, could you provide a detailed list of steps to reproduce this issue on our end?
- Could you provide screen shots of any other settings that may be involved with this issue?
- create a new actor blueprint
- add a MaterialBillboard component
- add a material to Sprite/Elements, such as DefaultMaterial
- change the scale of this component or parent component, you can see the screen size of the billboard is not changed all the time
