Hi @Pryme8 I think this is one for you Babylon.js Playground
outputSize has an effect but neither outputPosition nor outputRotation.
Looking at spritemap.ts you can see where outputSize is read and the plane adjusted but not the other two.
Is this because both position and rotation can be applied directly as in https://www.babylonjs-playground.com/#5DEJ3L#1? Therefore they are not really necessary.
I have removed outputPosition and outputRotation from the new docs.
Will put them back in if I am mistaken.
