What will it be like to walk into the second dimension of the living world?
Look at this girl with a pair of elf ears and swaying on the subway:

There is a cute and playful atmosphere between the hands and feet.
Ran goose...
Behind all the good, the actual "way to open" is this:
Yes, it is really in response to that jianghu "famous saying":
Behind the cute sister, it may be a big man who picks his feet.
I learned the truth...
In addition, there are "macho chirping" and "macho chirping":
But even so, the silky effect of this video still amazed many netizens:
Now the holster man moves so smoothly?
More importantly, all of this is still the kind in real time!
As a result, more netizens sighed after reading it:
It's time to become a pipe person (a person who is obsessed with and obsessed with virtual anchors).
How the macho man becomes cute in real time
Leaving aside the people in the middle, first reveal the true identity of Meng Mei:
An original Humanoid model, Yuki Sauce (ユキちゃん), a special structure in the Unity animation system, contains at least 15 human-like bones.
Yuki has a total of 6 expressions, which can be adjusted through 14 dimensions, 15 lip movements, and eye tracking.
Moreover, for 275 yuan (5,000 yen), you can take your wife home directly.
However, for Yuki to really be able to break the dimensional wall and move, it still has to rely on a plugin called VRM4U:
This is a VRM file importer that can be loaded when Unreal Engine 4 is running, and various features can be implemented after the import.
In the animation system, it is easy to reposition poses, including A poses, T poses (that is, our common characters have their arms outstretched), and also generate BoneMap.
Facial animations can be adjusted via Morphtarget/BlendShapeGroup:
Bones can also be shaken by selecting VRMSpringBone and PhysicsAsset:
At the same time, the VRM4U also has a generic ControlRig and an UMG for controlling the movements of the model.
At runtime, it supports redirection from UEMannequin to VRM models, motion capture data can also be received from external applications, and supports the VMC protocol.
On the model's materials, you can adjust the shadow color and outline color:
The thickness and shape of the model can also be adjusted, for example, the whole hand of the wife can be enlarged in key directions to create a special effect:
Even according to the authors, there are post filters and ray tracing that can be used at the same time.
VRM4U also supports forward rendering and deferred rendering, which can be easily applied to VR or AR.
Finally, this plugin has good compatibility with UE4 and can be easily adapted to versions as of August 2021 such as 4.20, 4.27, 5.0EA.
Unreal Engine, YYDS!
Unreal Engine, and epic games, the company behind it, are worldwide.
What the little brother used this time is the fourth generation of Unreal Engine (UE4).
UE4 was released in 2014 on a subscription model and has been available for free download since 2015.
One of its features is the use of voxel cone tracing's real-time global illumination, which eliminates pre-computed lighting.
Later, however, for performance reasons, this feature, known as sparse voxel eight-tree global illumination (SVOGI), was eventually replaced by a similar but less computationally expensive algorithm.
In addition to this, UE4 includes a new "Blueprint" visual scripting system that allows for the rapid development of game logic without the use of code, reducing disagreements between technical artists, designers, and programmers.
Many of the stunning videos that many enthusiasts on the Internet are diying now are based on this version of Unreal Engine.
For example, a foreign blogger has created an effect that makes people "silly and confused":
Some netizens exclaimed after reading it:
For a moment I didn't even know which side was the real world!
The latest Unreal Engine has advanced to the fifth generation, which is UE5.
At that time, as soon as its debut film appeared, it shocked many game enthusiasts:
Compared to UE4, Unreal Engine 5 mainly brings two new core technologies:
Lumen: Dynamic global illumination
Nanite: True virtual geometry
For example, each resource in the game uses a million triangle faces, and each frame of the game has more than a billion triangles.
UE5's Nano, which can be compressed losslessly to twenty million, completes the rendering of these triangles.
Nanite can also display triangles at the pixel level, and the shadows can be accurate to the pixel level.
Lumen, on the other hand, is blessed with full dynamic lighting and global illumination.
Unreal Engine 5 will be fully released early this year.
At that time, what kind of amazing effect will it bring?
It's something to look forward to.
