Hey there and welcome to Random Madness! This channel is about showcasing and discussing response mechanics in video games. Blood and gore effects, destruction, vehicle damage and so on. Here's an overarching video on this theme:

You can find the discussion videos of character responses in this playlist:

You can find videos on the topic of destruction and vehicle damage here:

If you like the music you hear on the channel, you can find it here. It mostly leans towards heavy metal, with elements of thrash, prog and other influences as well:

#### Hierarchical modeling of anatomical structures
Use multi-layered materials (4-6 layers) to simulate skin/muscle/bone, and control visibility through material masks
Add secondary collision bodies (such as muscle expansion bodies) to the skeletal system to achieve force deformation
Sample code:
```
// Add physical constraints to the bone modifier
FConstraintInstance* Constraint = SkeletalMesh->AddConstraint(
EConstraintType::Physics,
BoneName,
ParentBoneName,
FTransform::Identity
);
Constraint->SetLinearXMotion(ELinearConstraintMotion::LCM_Limited);
```
#### Real-time cutting algorithm
Plane cutting: Use UE5's APEX Destruction module and combine it with Signed Distance Field to calculate the cutting surface
Dynamic topology reconstruction: Use Procedural Mesh Component to generate a new mesh. Note:
- Vertex cache reuse (to avoid GC jamming)
- Dynamic calculation of normal smoothing groups (to prevent jagged sections)
