I'm trying to put my render with a background image which worked the first time, but when I enlarged the resolution of the background image in photoshop to twice its size (from 4368 × 2084 to 8736 × 4168) and put it back in blender (and after doubling the size of the render resolution to match) the render is going off screen as shown in the pictures. How do I fix this?

Here's a link to screenshots: https://www.flickr.com/photos/163507419@N03/?

first one shows how I want it to look (this was when it worked at the 4368 × 2084 resolution), the others show what it looks like now

thanks in advance

Also, if need be, attach your blender file using this: blend-exchange.giantcowfilms.com $\endgroup$ – Bruno Mar 22 '18 at 15:32

Without having your .blend and image files at hand, I can't tell for sure what is happening.

However, usually a "Scale" node (found under "Distort"), set to "Render Size" and applied just after the Image input, should guarantee that RenderLayers and external images have matching sizes. (Note: if the image is smaller than the render layers, it will be stretched, losing sharpness in the process)

I don't know, however, why they don't match already if – as you say – you already changed the resolutions in both the image and Blender. I can just suggest to check again.

  • $\begingroup$ Hi Nicola, I've added the blend file and images now, I'm about to check your method $\endgroup$ – Kenzo Caspian Burnett Mar 22 '18 at 16:08

  • $\begingroup$ Hello Kenzo. Glad it worked! However, I've checked your blend file: be aware that you have opened the file "hi rez 2" into blender, but you are still using the original file (Gas station.jpg) in your "Image" node! I don't know what sizes these files are (they aren't packed into the .blend) but you might want to check which one you're supposed to be using! $\endgroup$ – Nicola Sap Mar 22 '18 at 16:14
  • $\begingroup$ Ah yes i forgot to do that as well! thank you for pointing that out too $\endgroup$ – Kenzo Caspian Burnett Mar 22 '18 at 16:24
