Allow to repeat a geometry based on translation / rotation / scale / number of instances parameters.
Repeat can be added one after another.
/!\ this modifier cannot be masked
If that can help, here is a little video of basic repeat manipulations. But you can go way beyond that. I'm so proud of you, documentation reader. With that video you'll gain 2xp in creativity :
Repeat modifier can also be used to create things we use a lot in TV which is the infamous infinite zoom. Here is a quick tutorial to explain how to do it. The trick is to be sure no 3D layer (camera / group / mesh) is weirdly scaled, and then to do an animation loop on the camera the same size of the repeat modifier distance in the same direction. But well, just check it out ^^:
