Array [with offset Ob/curve] deforms mesh and decreases with size ...

Nothing really messy, it just shrinks the mesh a bit and every other mesh decreases with size…

Any idea why?

Not without something to look at.

Apply Scale to all objects (Ctrl+A)

Scale objects in edit mode, if you scale in object mode you’ll have to then apply the scale

Ah right! Thanks Rich, Applying location, rotation and scale to all objects did the trick!

Kinda funny… cubes are fine/same… sphere are decreasing with size a bit… and my own meshes tend to get [gigantic to reallly tiny]…

Works now, thanks man.

Cheers!
