If I recall correctly, the HrmnsOblivionScriptOptimization mod actually has a habit of breaking scripts when it "optimizes", try disabling it.
You should only have one of the SDR Perks And Patches running. I don't know what would happen if they are both active at the same time, but it probably isn't good.
I don't know what xeosp++ is, so if the above two suggestions don't work, maybe take a look at that?

Hope that helps.

I think I've fixed all the alpha value / chameleon refraction bugs, as well as a bug that was killing the npc's from processing their custom actor values (which may have been the cause of other strange behaviour and issues). The fixes will be available in the next update (whenever that is). I still need to transfer the sprint features out of the main .esp and over into the Perks and Patches .esps.

Just checking since I can't find it stated in the documentation but it's implied that empty equipment slots don't affect sneaking, is that right? e.g going barefoot is sneakier than wearing even the quietest shoes.

That is correct. The sneakiest way to move around (without magical interference) is in your underclothes.

Thanks for the clarification

Except now I have this image of the Thieves Guild arguing over the best brand of camouflage body paint

I'm halfway tempted to create an alternate Argonian sub-species that has chameleon powers naturally, but only if the skin is exposed, so the effectiveness will depend on what they aren't wearing.

P.S. to all:
I'm just about ready to release the next update. Working on documentation. If there are any other additional issues or requests, now would be the time, since I won't have time later.

I have now figured some well working ini settings out for me, concerning the offsets I would suggest you make them all so that you offset half the penalty with everything at master level(maybe a bit more for clothes) This ensures sound doesn't become meaningless and I think it would go well with my current settings.

And jumping gives the same penalty as running, plus the ini penalty? I only noticed a penalty for falling from a distance, but a normal jump didn't seem to have any impact.

@ Kobal, the jumping sound multiplier is further adjusted by how much air time you have, reflecting how hard you are hitting the ground and offset by acrobatics. As for the off-sets, without more feedback from other folks, I'm hesitant to change it, but I might consider making it more customizable in the future.

Looks like I overlooked one or two things. Nothing major that will prevent you from playing the current version, but I will be uploading a new update soon.

Here's a question: I am looking into allowing third party mods to add their own "adjustments" to the detection formula, by either adjusting the detector's bonuses/penalties and/or the target's bonuses/penalties. I original had four categories: audial, visual, skill, general. However, that would mean a total of eight adjustments to track (four for the target, four for the detector). I am beginning to think that simplifying it down to just the general might be the way to go, that way I would only have to have two "values" for modders to adjust. It would be applied after all other factors (sight/sound/skill) are calculated, and then adjusted for distance. Thoughts?

PS: The Wrye bash freindly package is not really WB friendly.

You have to have the 00, 01, etc. folders directly in the 7z parent file, not under another subfolder called SDR_410. Suggest selecting all 00, 01 etc. folders, and adding to SDR_410.7z. That way, WB recognizes them directly.

Aww, you didn't implement my requested feature. Guess it wasn't really a popular choice.

For which purpose? Does any modder plan on doing that? And for which reason would the regular means of affecting detection not be sufficient?

(re: cross mod option to adjust detections)
Actually, at the moment, there are no modders who have come forth requesting the details on the feature. It's come up before, but because my mod came so late in the game, and now with Skyrim released, there's just not that much buzz on SDR, or tweaking Oblivion. There's a little back and forth at the moment because folks are waiting on Skyrim updates and the creation kit (I don't have Skyrim, so it might be out now for all I know). However, there are a few mods out there that do affect detection in ways that SDR does not. For example, there is one called "clang" (I think) that actually takes into account when the player makes noise, and artificially boosts the detector's Sneak skill for a bit. Ideally, you do want to tweak the actual skill, just the ability to detect. So I wanted an option where other mods that would be good with SDR could just modify the adjustments. It's either that, or I could just ask for permission to incorporate the mod, but I haven't played with them long enough to know if that's the way to go. Anyway, at this point, I'll probably just let it go until a modder requests it.

Well, it was sort of a bell and whistle request, and you were the only one requesting it. It's still on my list of things to look at, I just didn't tackle it this time around.

Doh! I'm usually pretty careful about that. Whoops. I replaced the file on the Nexus with a properly packaged one.

Well that's true, but at least it's still on the list! Yeah!

You said that I could use AV uncapper to replace the chameleon curve setting you took out, which I did, but now I noticed it does not work because apparently SDR overrides it. May I ask you to make them compatible, or bring the chameleon curve setting back?

Well, in theory, this is how it works:
SDR calls for the chameleon actor value. But before that happens, AV Uncapper hooks it and applies the curve settings. That's what was happening before. So when you say "it does not work", what do you mean? If you are saying that the curve is not being applied at all, that implies that either the AV Uncapper example.esp was not activated, the curve settings weren't turned on, or some other mod/OBSE plug-in is conflicting with AV Uncapper. (The only one I know of is Elys' Uncapper)

Double check those things and get back to me, although you may want to post this on the AV Uncapper thread.

Sounds like the adjustment interface could be useful to lighting mods such as Cava Obscura so you don't have to manually tweak the ini.

I mean that I am invisible when I have 100% chameleon and that's only when SDR is turned on.

Are you saying that with AV Uncapper installed and SDR not active, your total chameleon value is different than with SDR active? Or are you talking about the visual effect of being transparent?

SDR does not alter the Chameleon value (at least not in any way I can see), but Chameleon's effectiveness is handled differently. Without SDR, a Chameleon value of 100 or more means you can attack and do almost anything without being detected. With SDR, that's no longer the case, because Chameleon has different effectiveness when it comes to sight/sound/skill.

What you are describing doesn't make sense. If you have AV Uncapper installed correctly, you cannot have a Chameleon value of 100 or more.

Could you check your Chameleon value with SDR activated and again with SDR not activated? The number should be the same, and if it's over 100, then there is something off with how you have AV Uncapper installed.

I've thought about setting up an ingame settings menu, but it's something I've never done, so it would be really time consuming, and also, I don't know how to make thos settings stick. Each time a saved game is loaded, the .ini file would be called and any ingame changes made would be overwritten.

What I did for testing is have the windowed option turned on and the .ini settings open in another window. Then whenever I needed to make a setting change, I would go into console mode, save the game, alt-tab to the ini file, make the change, save it, alt-tab back to Oblivion and reload the most recent save. It's not as slick, but it works. I just kept doing that until it felt right, then I switched out if windowed into full screen.

I might be willing to do an ingame menu, but only if there was some way to save the changes.

p.s. It wouldn't be too difficult to put the uncapper settings back into the .ini. But before I do that, I want to 100% be sure of what the actual problem is. For example, if it is a visual issue, maybe what is needed is a transparency cut off so that you can still see your character, even if your Chameleon value would make you invisible. And then have two settings, one for the player an ine for NPCs (which would allow them to be 100% transparent). The visual effect just gives you a sense of how "Chameleonized" you are, and does not 100% accurately reflect your Chameleon value (that's due to the Chameleon offset that is already in the system). There is already a minimum transparency effect, otherwise 10% Chameleon doesn't look like anything has changed.

I haven't double checked this yet, but according to my knowledge getAV only returns the normal vanilla value, so I know of no way to tell what my actual chameleon value is. But without SDR bandits continued to attack me when I reached 100 chameleon, so AV uncapper worked. Now when I activate SDR, I get a 0 in the visual detection category with the same amount in chameleon. That's all I can say.

GetAV Chameleon should return the hooked value created by AV Uncapper, but I will look into it.

I was actually thinking of people being able to make a compatibility esp rather than asking for all that work, though I'm a noob at modding so will be quiet now
I'm personally okay with editiing the ini, Recommended ini settings are fine.

AV Uncapper does not change your chameleon stat itself. It changes the way the stat is used in the vanilla detection formula. Since SDR replaces the vanilla detection formula, you will not see the effects of AV Uncapper on chameleon while SDR is installed.
