you can enter either Data property: which is a [n] two dimension array.
Or provide Xdata,Ydata and Zdata.
You should not type in [u]nangle [/u]as [u]Data[/u] property (remove it, if you want to specify px,py,pz)
Position and Size is used to move the whole polygon (displacement).
Do not need to enter anything inside that group unless you know what you were doing.
(remove all those values)
There are too many GUI elements, I do not know how to fix your ejs source.
Please try it again by yourself!
