Hi @Paris_Rosek , it’s not a bug and I see the same thing often when I’m setting up PI.
Try playing with these two sliders:
They represent your maximum and minimum colour value, which allows you to set the colour scale to what is most useful for you on that planet.
If you move the one on the right even further to the right, you will notice a lot of the white colour on the planet turn into other colours. Move them around until you can more clearly see where the hotspots are!
