Quality doesn't seem to be working as it should.

Post by ArsStels »

Playing in my save with modifications I noticed such a thing that the quality :any-quality: works as if not quite correctly. Not as it should be. In simple words: if the chance to make something UNCOMMON from NORMAL is equal to or higher than 100%, then we will get 100% UNCOMMON. If we also have a chance from UNCOMMON to RARE 100% or more, but we create it from Common materials, then we will no longer get a RARE item with 100% quality. And now I will show examples of screenshots with and without mods.

I don't think it was supposed to work that way, even though a base game doesn't have such a big jump in quality.

Here I show how it affects a nearly vanilla game. 1 - we should also have almost 100% chance of getting high quality items. 2 - produced 7 items. 3 - and all 7 out of 7 are just uncommon.

In the vanilla version, everything works as it should.

This is where I was supposed to get the highest rarity level.

Here I should have received at least legendary items.

I am not considering it to be a bug. This works exactly as it was designed: quality percentages give you probability of the first quality bump. If each following quality bump would have same probability then at some point everything would be legendary only. Table you have is just first quality bump and additional quality bumps have probability reduced by a value called next_probability. In SA if you have quality of 100% then you are guaranteed uncommon from common but second quality bump happens with 10% chance. To get guaranteed rare from common you would need +1000% quality.

As I understand it, this can be changed :not-enough-repair-packs: if there is such a parameter?

Although, I think so. I haven't noticed this property in quality module prototypes before. So, there is most likely a bug in the mod description :not-enough-repair-packs: that gives information in the tooltip. :geek:

The question is closed.
