[ue5] animation redirection: how to import magic tower characters into the game

pmx Import ue4 Methods , I use this blogger's .
Need to give blender Next plug-in , hold pmx convert to fbx Format .

One 、 Import UE5 Post material treatment

1. Create materials

Directly create materials , You will find that the created material is white mold .

Here you can use a relatively simple method , Do not create a new material when importing , But after importing .
After importing the model , Then import the map , That's it TGA file .

Select these maps , Right click and select Create material .

Automatically create the corresponding material .

2. Give material

Open the model mesh Bone mesh , Next, assign materials .

Drag the shader directly into the corresponding box , You can see the material of the character .
Can open blender Corresponding to the given material .
Several material boxes may use a shader together , For example, cheeks 、 tongue 、 The nose uses a face shader .

The material is given , Remember to face blender Check the original model in several times , See if there is any wrong material .

Two 、 Add animation （ Redirect ）

Want to add animation to characters , The imported character bones must correspond to the animated character bones , Redirection is needed here .
As long as the naming rules and sorting of bones are the same , You can use each other's animation .
Here is a little white man to demonstrate , The bones look clear .

Mixamo Action import UE5

Here we will add other model animations to the little white man .

1.IK Binding bones

First import characters —— Import action , Bones select the bones of the character just now .
newly build 2 individual IK binding , Let animated characters and little white bones map to each other .

Open animated characters IK binding —— newly added 6 Chain ： head 、 trunk 、 Limbs

Click on the pelvis , Right click to set the root of redirection .

Set up 6 The starting point of a chain 、 End bone .
The starting point and the ending point should be on the same bone chain , For example, the arm only reaches the wrist , Don't reach five fingers .
**

Because five fingers are actually five chains , Will create 5 Bone chain .

**
There are two ways ：
（1） Select directly in the initial bone and end bone .

（2） Select the bones in the hierarchy , Right click to create a new redirection chain .
This method is more intuitive , I usually use this .

Exclude rotating bones when setting up chains , Otherwise, two chains will be created .

For little white people IK binding , Ibid .
The chain name and quantity should be the same .

Unbreakable bones are more complex than little whites , There are many more bones on a bone chain , Just keep the position of the initial bone and the end bone similar , It can still correspond .

The redirection root is also set at the waist .
You can adjust the redirection root according to the actual situation of the animation .

2.IK Redirector exports animation

The bones of the two figures have passed IK Binding corresponds to , The next step is to use IK Redirector will mixamo The animation is exported to the animation of little white people .
newly build IK Redirector .

IK Bind select animated bones .

open IK Redirector , The goal is IKRig Assets choose white people .

Check the target chain and source chain names .

Adjust the posture of the little white man to be the same as the character .

Choose animation .

Export animation .

Open the animation blueprint of the little white man , The animation we just exported has been added to the animation assets .

With IK Redirector , We don't need to export animation one by one .
You can redirect the little white man's animation blueprint directly

You can select the redirector that you want to bind the target of the animation .

Will export the animation used in the animation blueprint .

3、 ... and 、 Add characters to the game

You can replace the character grid directly .

It cannot use the animation blueprints of other bones , It will be like this .

Choose the animation blueprint corresponding to its bones , You can directly control the characters in the game .
