Prerequisites: Setting up Unity Modeling the mesh in Blender Configuring the part in Unity
This tutorial will help you setting up reentry effects for your KSP2 modded part by guiding you through creating the reentry meshes and setting up everything needed in Unity.
Introduction
Reentry effects for parts in KSP2 are based on a custom shader which creates some flames coming out of an envelope surrounding the part (see Figure 1).
This envelope is defined for each part using a set of what we'll call reentry meshes. These meshes are set up in order to have a Level of Detail (LOD) system where a high fidelity mesh is used when looking at the part from very close and a less detailed when when looking from afar.
