Have Simple cube or Spherical collision less performance cost in UE4?

I’m wondering this what is cheaper, a cube collision have less polygons, but a spheric collision can be easy caluclated with radius.

Hey WarMachine,

Technically a sphere would require less work because it only needs to calculate radius, whereas a cube would have different distances from center to edge depending on where collision occurs. You don’t need to worry about polygons on a collision shape because it’s not being rendered so it doesn’t technically have surfaces. difference is likely minimal, however, so it’s probably best to use whichever is appropriate for situation.

Hope that helps!

Thx, it make so sense but wasn’t sure.

Doubley thank you for this :slight_smile:
