Quick Start Guide for UCX Collision – Getting Started | Unreal Engine 5

In part four of this tutorial series, I will show you how to quickly make UCX collisions for UE5.

The Problem

This was a requested tutorial

Let’s start with a basic ramp that I made in Blender

I will import this into Unreal using the Auto Generated Collision

When I play the Level, notice that the Character cannot walk up the ramp

This is because the Auto Generated Collision in Unreal is a box

UCX Collision

To fix this problem, we can make our own collision shape in Blender

In Blender I duplicate the ramp

I rename the duplicate UCX_ramp – it is very important to rename the collider the same as your mesh

Select the mesh and the collider and export them as FBX

The Solution

Back in Unreal, I import the new ramp

I must deactivate “Generate Missing Collision” for this to work
