Yes I would like that very much. Even if I don't see it, it would be nice to believe my character is comfortable, and not chafing under that armor.

You are correct, it is because of clipping. If you look at Morrowind armors, they are basically the same mesh with different textures, unlike Oblivion armors which have distinctive meshes for each armor.
If you open up the base body in Blender, then open different armor sets on top of one another, you'll see all the clipping that occurs. It wouldn't be possible to achieve layers without creating complete body part meshes for each layered item.. you maybe could get away with pauldrons, but only using big pauldrons on the less bulkier cuirasses.

One "cheap" way to create the illusion of undergarments would be to re-texture the base body mesh with some sort of clothing texture.

I misread the thread topic at first and thought you meant clothes over armor LOL. I agree, I think that it would add a nice touch to it, even if aesthetic.. they always include so many different types of clothing in TES it would be nice for all classes to utilize it.

That would be incredibly awesome! I would love that.

Well for example Soul Calibur IV

An example of such system, you can decide by self looks its like crap or not, but I don't see cliping and gaps but I see animated parts on clothing, so layering can be achieved in proper way, http://www.youtube.com/watch?v=jY2QWXk_NsU& but when modders receive such system as base number of unique armors will be expanded even more.

Clipping occurs and with Oblivion equipment, so removing of slots does not fix it, also removing certain slots make some parts of armors looks like created out of rubber, adding some additional bones can fix such flaws, new skeleton for example similar to skeleton of Lich in Oblivion and has pauldrons bones so pauldrons will not flex with hands anymore, they are done out of metal after all not from rubber.
Also additional parts like bags, belts, straps, amulets etc can be added to base mesh so even just retextures of robes like was done in wrong way in Oblivion http://www.tesnexus.com/downloads/images/37594-2-1300216010.jpg (but having real unique items still better)
So at last layering of such additions will expand variability more.

Holy crap, that would be awesome for enchanting.

Definitely clothes under the armor. Think about how cold it would be if you were wearing armor, (made out of metal) and wearing nothing underneath it and walking around in the snow and mountains.

I never meant normal clothing, they would probably wear layers of wool and linen or some other thick fabric.

Of course they might have worn their usual clothes under the fabrics aswell.

What am I looking at? I don't see anything in those clips remotely related to the discussion.

I think there's a language barrier here, so I'll just leave it at that.

Well thous videos just example of equipment layering done in without significant cliping and gaps like you say, at the same way can be done and layers in Skyrim,
so clothes will under armor and such clothes can be seen at places where armor not cover.

Any changes over Oblivion model of equipment, will be better even if layering will be not so significant and just affect small details like pouches amulets and belts on generic base, if devs again repeat they mistake with robes and armors, thats differ only in texture.

definitely, and just make it that you can't wear two enchantments on torso section or whatever. I mostly want this though so that we could see the clothes under the armor, so maybe the half naked nord guy in that mostly exposed armor could actually look cool with my fav duds under that armor.

I kinda doubt it though, didn't they say equipment would have each own slot? so unless you can stack clothing and armor in the same slot or if each part of the body has two slots, I don't see this happening.

I don't know how it is going to work with Skyrim, but FNV, you can use armor addons, which basically allows you to put 2 objects on the same slot. So, you could have a clothed model, then have say a briastplate added to the model, and in game, you'll see the NPC wearing his/her clothes with the briastplate on. It works fairly well with meshes made purposely to be stacked on on top of the other. The issue with armors in Oblivion, and surely will be the same in Skyrim, is that the different armor and clothing meshes are not created with the purpose of being stacked one on top of the other as they have very different dimensions even to they are rigged to the same skeleton, so if you do that off the vanilla meshes, you are going to have a lot of clipping and "hovering" armor around you.

It is not impossible to do, but to look good, the devs would've had to create armor meshes with the intend of stacking different armors on top of each other, or additional "pre-stacked" meshes.

There is a FO3 mod called Taylor-Maid which attempts to do this with accessories like belts, bandoleers, neck bandanas, etc... it is a great idea and looks fairly well, but you can see in a lot of models that the accessories just don't fit right, and that some have been altered from the original meshes in an attempt to fit properly. For a mod, it is great, and I am not putting the mod or the modder down, but I don't think a paying customer would accept that quality in a game.

I think it should be in the game; in Oblivion I always felt alkward when my character was naked under the one piece of armor I desided not to wear. The only thing I fear is it might glitch and make something to where I was wearing 2 shirts or 2 chest plates ect. [kinda like the potion drinking glitch in Oblivion].

I really hope we can wear clothing underneath armor.

very much yes to the clothing under armor, especially given all the screenshots we've seen so far, looks like our char'll be a little cold if he goes out without a shirt.

YES!!!! PLEASE!!!!

Robes can be put over light armor
all armor supports having clothes underneath it

And the enchanting power
Exquisite belt, rings, amulet, pants, AND shirt!!! Plus all that armor! It's all just Begging to be enchanted!

Yes, like in Morrowind.
