Creating a Hit Impact & Bloody Effect in Unreal Engine | VFX Tutorial

Hello everyone! I am Asif Ali, and you’re watching CGHOW. Today, I’m going to show you how I created this hit impact and bloody effect where a monster bursts out with blood and mesh on impact. Let’s dive in and see how it’s done!

Effect Breakdown:

In this tutorial, I’m using a delay for the blood effect, triggered by the animation of a monster. Here’s a detailed breakdown of each component:

1. Monster Animation & Timing:
   • The monster walks and then disappears after a 4-second animation (downloaded from Mixamo).
   • The hit effect starts with a delay of 3.8 seconds, timed perfectly with the animation.
2. Blood Effect on the Ground (Decal):
   • The blood decal material is a variation of a frozen texture I created earlier. I simply changed its color from white to red.
   • The material is applied to a planar mesh and multiplied with the particle, saturating it for color variation and eroding it over life.
3. Blood Drops (Part 1):
   • After the hit, blood bursts in drops, which are controlled by a Niagara emitter.
   • Particles spawn with a random life and velocity, and gravity pulls them downward.
   • I use a 3×3 sub UV animation texture for the blood drops.
4. Blood Drops (Part 2):
   • A duplicate of the previous drop is created with similar settings, but this time using a blood splatter material.
   • The dynamic parameter erodes the material over the life of the drop, creating a more realistic spread.
5. Spreading Blood (Part 3):
   • A third variation of blood drops is spread horizontally by adjusting the velocity along the X-axis.
   • This creates a more dynamic and chaotic spread effect on the ground.
6. Body Part Erosion:
   • For the body part, I use a static mesh of a zombie that erodes over time.
   • The material erodes with a noise texture, and the body part interacts with the world using collision and gravity settings.
7. Mist Effect:
   • To add some extra flair, I added a puff of mist that appears as part of the blood impact.
   • This mist is created with a cloud texture and a random velocity, filling the space to enhance the overall effect.
8. Projectile Trail:
   • The projectile trail is animated using a sphere and velocity settings along the Y-axis.
   • A ribbon texture is applied to the trail, creating a nice flowing motion as the projectile moves.

Viewport Breakdown:

Let’s take a look at the full effect in the viewport:

• Decal: Blood appears on the ground.
• Drops: Blood bursts in drops, followed by spreading blood and body parts.
• Mist: A mist is created to fill the scene.
• Projectile & Body: The projectile hits, and the body part erodes, leading to an intense and dynamic scene.

Customization Tips:

You can modify this effect by:

• Changing textures for the blood or body parts.
• Adding additional debris, like skulls or limbs, to make the effect even more gruesome.
• Adjusting the particle system to get the desired look for blood splatters, drops, and mist.
