QUICK DEV TIP #110 UE5 - Thicken Trigger Volumes

I discovered today’s Quick Dev Tip a while back, and it’s something that can help remove a lot of frustration while working on a busy level!

Did you know you increase the thickness of trigger volumes, making them easier to click!

I’m sure you have run into this problem before; You are trying to select a volume, but you keep mis-clicking because the lines, by default, are so incredibly thin and hard to click on!

Even in my empty level example below, it takes me three attempts to select it… so you can imagine how frustrating this becomes in a busy level full of actors, clutter, and overlapping components.

We can reduce these mis-clicks by simply increasing the thickness of the volume’s lines. It’s a super quick fix.

Just select your volume, head over to the Details panel and look for the Line Thickness setting.

You can see in my GIF below how increasing this value thickens the lines, instantly making the volume much easier to click on!

I’m pretty sure this setting exists anywhere you’re using volumes. In my example below, you can see it working on a Trigger Box, a Sphere volume, and even a Box Collision component inside a Blueprint.

Obviously, the thicker you make the lines, the more they’ll start to occlude your view of the level. So it’s worth finding a thickness that suits your own preference.

And remember, like in my GIF below, you can always press G to toggle Game View. This hides all editor-only helpers, letting you see your level cleanly without those big, bold trigger volumes getting in the way.

So now you know how! I hope you found this useful and that it saves you a bit of frustration when building out your game!
