Ok you have a lot of questions so I will take them one by one.
vi363R is not mute. He came on the scene sometime after the launch of KE and was mainly doing re textures, he only recently got into doing his own mods and ports, and bathing suits seems to be his favorite thing. I can see why you say that as Mute has similar taste and aesthetic with his mods. See below for Mutes stuff

As for the pictures on the front page, no they are not Daz or Blender Renders. These all require Hook5 Basic at least. Some things are little bit easier done using Hook5 Extened due to the Custom Skin System, Hairworks, Lighting and objects but if your looking purely at model fidelity H5 Basic will suffice. You will probably not see anything close to H5 unless PervK makes it.  3D Sexvilla 64 Bit added enhanced graphics engine including metal mapping and normals. I actually have run it before. It is actually more akin to Hook4 with Bump Mapping and Specular.
As for KE Update 1, there are a lot of things we have wanted to do that requires updates to core system files and scripts, so we just decided to make our own update. Like a fork. Specifcally KE Update 1 reenables Butt Sliders that seem to have been disabled since before v7.5, we enabled them and modified them a bit for our own use.  I don't have a perfect example but if you check the video below, the last few seconds, the sliders give you a much better butt jiggle.  Sorry for the video plug it was the only example I had.
In addition responding to 
Big_Mirror (Thanks for the kind words), XBody is a Body mod based of of PervKs Female Body v2 (FBV2). The whole idea of the mod was to be able to create morphs to fine tune every aspect of the body to your liking, about 250+ Morphs in total.  In addition it also includes what I call Full Body Morphs, which allow you to morph From FBV2 to NSB121, to MCCThic, and over 50 other bodies just with a slider. In addition there are about 30+ PE Morphs added to handle things JCMs and other little tidbits we wanted to add.
The update integrates XBody Default as the default body going forward.  This will allow easier use of the new Anti Clip Morphs tab we added and all the 200+ Body Morphs that come with XBody. It is only the first update as we want to start rolling in some of the items that have been made in the community default into the game.  Things like the

, Additional Body Sliders developed by Driver, and other quality of life updates from MrOllyK.  There is a lot so we are taking our time.
We will try to keep interested parties updated with things here, but let me know if you are still having password issues and we can try to get that resolved for you.
