Decimate Modifier works a little bit different on my base

[Manny3D]

Hi everyone I noticed that when I apply my decimate modifier to the base if I go as low as grant, it damages the shape. However if I keep it at around 304 face counts, it gives the base house a somewhat similar shape to Grants. Just wondering how is this happening?

Thanks,

These things are relative to the model, its shapes, etc. I would not get hung up on trying to match Grant’s numbers, just get a lower count while retaining the overall look.
