Block Rotation Question

[Orphen 1]

I've been looking at the blocks we can place that can be rotated in 45 degree increments and can't seem to figure out exactly what property allows them to do that. I've made a couple of new blocks utilizing some existing models to do different effects but I've noticed that when placing the original block that uses that model it can rotate 45 degree increments but my new block only rotates 90 degree increments. Can someone point me at what property needs to be used to allow the additional placement options?

<property name="AllowAllRotations" value="true"/> <!-- enables the 45 degree rotations -->

Supposedly that's what makes it work at 45 angles. I didn't test though so idk if there's more to it than that.
