Hello, I am trying to draw a texture over the screen that has the same resolution as the screen, It has to cover the entire screen, so I am using the ScreenAlignedUVs node in the material editor. However this does not work if I put any kind of aspect-ratio on the camera. ![114074-screen.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/a/7/9/a790e8fc65da880e87fe5bf77ddf3e45cdfecb6c.jpeg) The node returns (0,0) at the top of the window (green line), but I need to have it start at the top of the view (blue line) I want it to be dynamic so I can change the width and height of the window. Is it a bug? Or am I looking in the wrong place. I can calculate the offset but I have to be able to get the window size somewhere, and I can not find this node. A custom node with Frame.RenderTargetSize returns some kind of buffer size that does not grow smaller only bigger and that is not usefull in my case… I hope there is an easy fix 🙂 , Elias ---

Bump, In my image I marked the green line with screenposition, but I meant ScreenAlignedUVs, the node that is pasted on top 🙂 ---

Hey thank you for looking in to this. Could you maybe point me in the right direction to fix this issue? Or do you maybe have a workaround for this? For example the way I can get the window size in the material editor? Any help is greatly appreciated! 🙂 ---

Currently the only workaround I can think of is to use a panner to push the texture coordinates to the right and down so that you account for the letter box (black bars). If you use a static number in the time input the panner wont scroll over time so you can just change the speed x and speed y accordingly to match your screen. Speed x and Speed y aren’t exposed in 4.12 though they are in 4.13. To get around this you may need to use two panners and in the first set speed x to 1 and speed y to 0. Then attach a scalar parameter to time so you can control the x position. For the next node do the same for y. I hope that helps, Ed ---

If anyone is interested, I was actually able to get the effect I wanted by changing the Mapping in the Screenposition node from SceneTextureUV to ViewportUV ![117442-fix.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/7/e/87e5798cad2752db6e1222a7dc6aa37df14e6977.png)
