Hello, I saw a mod on the Nexus (http://www.newvegasnexus.com/downloads/file.php?id=38047) that supposedly 'fixes' leveled lists. Aside from the fact that the plugin that was uploaded is entirely empty, this made me curious about the iLevItemLevelDifferenceMax game setting. The gamesas GECK references didn't have anything on it, and now my curiosity is piqued. The author of the above mod contends that it keeps all leveled lists from working correctly. With iLevItemLevelDifferenceMax set to 0, he says, this results in leveled lists only appropriate for the PC's current level to be invoked, and never ones below or above.

In part I believe the mod author, because at level 28 I don't ever see tier 1 or tier 2 items for sale. I would think that were the lists working, I would get tier 1 to tier 4 items offered to me (for vendors that had all such options, like Vendertron). Instead I just get tier 4 items. Now, because the game setting is iLevItem, I don't believe this single setting controls all leveled lists, just item leveled lists. So my question extends to the behavior of the iLevCreaLevelDifferenceMax and iLevCharLevelDifferenceMax settings. Are these the equivalent for leveled lists dealing with creature and NPC spawns, respectively?

All of these settings are set to 0 right now (vanilla FNV). The mod author states that setting iLevItemLevelDifferenceMax to 30 would fix this issue, but if the description is accurate, that would cause vendors to offer tier 4 items to any level character. I'm not sure that's such a good idea.

So here is my question: how do these settings work? If I wanted vendors to carry items AT and BELOW the correct tier for my character, should I iLevItemLevelDifferenceMax setting to a negative number, like -30? What do the iLevCharLevelDifferenceMax and iLevCreaLevelDifferenceMax settings control? If I set both the *Char and *Crea settings to some positive number, say 5, does that mean I could encounter creatures / NPCs at a higher Tier than my current level classifies me at IF I was within 5 levels of the next tier?

TL;DR version: wtf does iLevItemLevelDifferenceMax, iLevCreaLevelDifferenceMax and iLevCharLevelDifferenceMax control, and how do positive / negative numbers effect them?

Since it's 0 by default Obsidian probably thought they'd removed the behaviour from the game, or something, so it may not be entirely accurate.

Thanks, so do you think it's fair to assume that the Crea and Char variants are just thresholds for creature and NPC spawning from leveled lists?
