Accurate collision for a low poly landscpe

I’m fairly new to Unreal, but tend to pick up software pretty quickly. I’m trying to create a pretty basic low poly scene, but am running into problems with collision regarding the landscape. You see, the landscape tool in unreal is nice, but it doesn’t yield the low-poly look that I want for the scene. Thus, I modeled the landscape in Blender and exported it as an fbx model. During my first attempts to get it into the scene, I used the method in Blender where you make a copy of the model in question and rename it to, “UCX_ModelName”. However, this doesn’t yield the high-accuracy results that I need in a landscape. However, when I try to use the auto convex collision generator in Unreal, it takes a very long time if I set the accuracy to 1.0. Thus, I’m concerned about it’s effects on my computer’s performance.

Some notes on my system:
I’m running Unreal on an HP Envy that has:

  • Windows 10
  • An i7 quad-core processor
  • 16GB RAM NVIDIA GeForce 740M 2GB DDR3
    Graphics Card

Thoughts? Suggestions? Am I being an idiot? :slight_smile:

You can go into the Static Mesh Settings and set Collision Complexity to “Use Complex Collision as Simple”. This will do poly testing for collision instead of using a defined box. This gives you maximum accuracy, albeit there are performance implications depending on your scene. That said, my current project uses a very large detailed terrain and we experience no performance problems.

Thank you. I’ll try that now…

Wow! That’s exactly what I needed. Thank you.
