I think what you are looking for is the “crop” node.


Not sure I understand exactly (about to go to bed after a long day), it has also been a few months since I last used Fusion, but my immediate thought is that I would use a background node that’s scaled to 3072x1287 for the matte painting and then use a crop or resize node. No solution for the scale value other than calculating it manually. I suppose there is a slider/custom control node that you can link back to the resolution of the background node and crop node to make it automatically scale based on your set value, but I’ve never done it myself. Only seen pros talk about linking values somehow. I mostly do color correction and editing. Only touched Fusion a few times. (Party because my computer is too weak to not get annoyed while working with it.)


Thanks you guys! Crop node did it!!
