Replacing the image for the Homescreen is relatively simple. All you need to do is replace the texture Under the ‘Colors and Normals’ Section of the Screen-Home Material. Extra example Backgrounds are provided under the ‘PhoneSystem/Textures/Screens/ExampleBackgrounds’ folder.
The image used as the background should be a 1024x2048 image to prevent any stretching. Though images that are not the correct size should be automatically resized to fit.
Replacing the images in the Gallery is slightly more involved. Especially if they are not the same aspect ration as 1024x2048. The Gallery consists of 6 Materials listed as PhoneScreen-Gallery0 through 6.
The first step of replacing a gallery image to replace the texture in ‘Decal 0’ under the ‘Decals’ section of the material.
If the image is wider than it is tall it may be a good idea to rotate it by 90 degrees under the Positioning Section.
From here you need to modify the scale of the image in the Positioning section to fit it to the screen. You can either do this by eye or use math for it. For the math I would recommend making a copy of this Spreadsheet and inputting the dimensions of your image into the fields there and copying the resulting Scale into the Positioning section of your material.
If you made a duplicate of the Gallery or HomeScreen materials instead of changing the default ones you’ll need to replace them in the animation and/or replace the animation itself.
The Screen animations themselves can be found under: ‘RuneFox/PhoneSystem/Animations/PhoneScreens’
You can make a duplicate of these materials and/or replace the Mesh Renderer Material reference in these animations to change the material they use.
If you’ve made a new animation you’ll need to replace the old animation in the Animator. These Screen animations are used in the Phone_BlendTree state of Phone_DBT layer of the animator. Specifically, you’ll find the animations under the ‘Phone Screen - Apps’ sub-blendtree.
