I was looking at some speedruns and saw that at the start of drip120's speedrun, there's pieray in the worldpreview of every loading world. So I tried to search up how to do it and nothing came up. I'm using SeedQueue and drip might be using a multi instance setup since I can't find any way to this. Asking if it's possible for me to setup pieray in worldpreview and if so, how?

The pie chart u see in the start of drips run on the wall is just a bug and the chart is actually from the previous world not updating giving no info at all. There is a way to see the pie chart but this is illegal for speedrun.com
