How to Make Monster Parts Flash White on Hit in Unity?

lla

Hi everyone,

I'm working on a large monster with a part-breaking system. I want a specific part (like a "slot") to briefly flash white when it takes damage, similar to a hit reaction effect, without changing the entire monster's material permanently.

I've been searching for hours but can't find a clear solution. Ideally, I want to:

Target a specific part of the monster mesh.

Make it flash white for a very short time (like 0.1–0.2 seconds).

Then revert it back to its original color automatically.

I'm using Unity (2.5D/3D hybrid) and the monsters are made of separate meshes for different parts.
Is there a recommended approach for this? Shader-based, material swap, or something else?

Any advice, examples, or references would be really appreciated.

Thanks in advance!

To make monster parts flash white on hit in Unity, you can use a shader approach. One effective method is to use the Spine/Skeleton Tint Black shader, which allows you to tint the darker colors instead of the light ones. This shader can be used to create a flashing effect by adjusting the tint color to white when a part is hit. Alternatively, you can use the Universal Render Pipeline/Spine/Sprite shader and adjust the Emission color or enable Color Adjustment to set an Overlay Color to white. This will create a flashing effect on the specific body part. Ensure that you set the color's alpha value to make the overlay visible. You can also consider using a custom shader with a flash effect, as described in the forum discussions, to achieve the desired visual feedback.
