HDT Skyrim Ordering Independent Transparency

So I've always looked at this mod thinking maybe one day it could get integrated into ENB or at least I could find a way of fixing it, https://www.nexusmods.com/skyrim/mods/5 ... escription looking a the description the source code link is dead but it does not seem to use any real complex hacks to achieve its result: the author speaks about using Depth Peeling to achieve Ordering Independent Transparency it seems to be using a modified NIF like with HDT to apply the effect on the meshes:
1. SLSF1_ZBuffer_Test, SLSF2_ZBuffer_Write
2. NiAlphaProperty:Enable Blending = true, Source Blend Mode = SrcAlpha, Destination Blend Mode = InvSrcAlpha

Now is this doable in Skyrim SE? using data from both HDT and ENB like the original mod?

Re: HDT Skyrim Ordering Independent Transparency

I dont know, never thought about implementing it and by performance it's very unfriendly to cpu when many characters are visible. I dont even have anything to test this feature. Dont think it worth to do now, so rare can be required, but mod for SE so far from end.

I don't know if you're currently interested in adding it to the ENB. Its main function is to allow multiple tattoos to be properly displayed under transparent clothing. In the original Elder Scrolls, whenever you wore transparent clothing, some tattoos would start flickering in the transparent areas, and they would completely disappear when you entered the water. This mod solved that issue in LE, but there is no similar functionality in SE yet.

I will second this ask.
Transparent clothing in Skyrim is fine only when used separately. As soon as you add second layer of a mesh which also uses alpha channel, rendering starts to misunderstand whats going on.
Two best examples of when it can happen are
- Transparent outfit with transparent lingerie. Under specific viewing angles the part which is 'below' (in other words one piece is further away from view point than another and they are on a same line) becomes invisible
Same happens with tattooes - as most of them are transparent to a certain degree, they act the same way as clothing piece in this case, causing it to be invisible under the clothing. Especially noticeable when clothing piece covers only a part of the tattoo - in thos case covered part becomes invisible, while non-covered does not.
- Transparent weapons with transparent clothing (glass weapons for example). Especially when there is no sheath for the weapon - when you turn char so that it is behind transparent cloth, piece which is 'covered' by said pice will become invisible

This is more or less fine when the char is static, but once it starts to move the view angle is changes constantly, which causes texture 'below' the transparent piece to flicker.
I do remember I used the original mod, and did not notice any performance impact - moreover, 10 years passed since it was released and systems became way more powerful. Think of full SMP clothing/hairs on every NPC in town - I can hardly imagine it back in 2014.

Effectively this issue prevents usage of transparent clothing which has more than 1 layer, as well as using transparent clothing with tattooes - which is actually way more interesting way, as you can see it 'below' the piece of cloth.

Hope someone can re implement it in SE.
I can only play the role of a non-technical fool among them
