I am rendering in lower resolution, but background is not scaling down to match when rendered I am trying to make a scene with camera math (using Blender v2.91.0).
When I test-rendered the scene, it took all day to render, even though it is a very simple scene so far (my computer is not very fast).
So I would very much like to reduce the render-resolution to speed the rendering.
But when I set set the Resolution to 50% (or something else smaller then 100%) it only scales the rendered elements down, the background image it put in full size cropped (It correct in the viewport and when I render in 100% resolution).
I have tried all I can think of, to correct this: &quot;Frame Method: Stretch&quot;, &quot;Frame Method: Fit&quot;, &quot;Proxy Render Size 50%&quot;
And I have spend a long time trying to Google solution, but with no luck.
I guess, it is a simple thing, I have missed, and I hope someone here can help me.
The first picture is how it is supposed to be (screen dump from viewport).
The second picture is how it looks rendered in 50% resolution :(
No, blender will not automatically resize the image when you render at 50%. It will only render 50% percent of the pixels around the center of the image (Think of the percentage not as a resize, but as a crop).
If you want to resize use a scale node, set it to render size and Fit, so that the image is rescaled using the output resolution.
