In this demo: https://nme.babylonjs.com/#MXHRPH#2
It just simply output the texture, but source image is:
And output is:
According to NME procedural texture question - Questions - Babylon.js, I knew that’s because the
screen.position(position2d)block is in
[-1,1]range, just wonder why it isn’t
[0,1], and I can’t find any explanation in Babylon’s document.
Any help would be much appreciated.
