If you happen the situation that the shape of your object was collapsed by Lattice Modifier like for example, following case.
[Before applying Lattice Modifier]
[After applying Lattice Modifier]
Just applying, the shape of the target object was broken.
(This is a face of Merlion 3D model I created…)
The reason is that when adjusting the Lattice flame to fit the target object in Edit mode, this phenomenon occur.
When you adjust the Lattice to fit the target object, you should do in Object mode!
I hope that this information can help some creator having this issue and myself in the future who always forget that kind of tips.
