To create this Matte Painting, I got given a multitude of different images, from an Aztec pyramid to the rocky mountains.
I went into Photoshop and used the blue channel to edit out the background by altering the levels of the channel and did that for every image that I was going to use.
After using the channels and levels to make transparent I added all of the images to one new 1920×1080 composition scene. And then changed the order of the images as well as scaling them to size relevant to each image present.
To make the mountain not blue, I used a curves adjustment layer to edit the colour of the blue mountain to make it seem a brown to make it fit into the scene.
To join up the tree, Aztec, and grass layer’s grass, I used the clone stamp tool to blur each of the layers together so it does not look like 3 separate images put lazily together.
To use the Matte Painting for 3D projection, I imported a PNG image of the matte painting into After Effects. I made all of the layer 3D by clicking a 3D box icon next to each of the layers within the timeline panel.
After creating a camera, I then went into the top-down view and dragged each layer to their relevant space within the scene, so the background clouds will be far at the back and the branches will be close to the camera.
I then used 2 keyframes within the camera’s options to zoom into the 3D projected matte painting. After sorting out the keyframes, and camera position start and end position, I finally rendered the quick footage as an MP4.
