Seedray

[RoHVen_15]

Since 1.20 seedray doesn't work properly.

I assume that you’re testing on a world where you can use /seed to assure that it’s correct? Are there any particular ores that don’t work or all of them?

[RoHVen_15]

Not all ores are well positioned. The seed is correct.

Do you have a screenshot example from spectator/xray?

This is what it looks like when xray and seedray are used simultaneously.

It is normal for not all ores being correct, certain ores are also more probable to be correct than others. I have to do some further tweaking for 1.20 & 1.21
