"Get Random Point In Radius" will leave one square sector empty. Seems like it creates patchy "random" placement as well, clearly defining square sectors.
Needs to return vectors in all areas within radius more evenly. Not "random" enough currently. See forum link for example image.
1. Create an actor BP
2. Add an instanced static mesh component
3. Use a for loop to Add Instances (see example image)
4. Add actor
5. Set amount to Add to 25,000
