====== WatchMaker 3D FAQ ======

===== What do I need? =====
  * Make sure you have WatchMaker 7.0+ installed on your phone and watch

===== How do I create a 3D Watch Face? =====
  * Create a new watch as normal by tapping dots in top right corner > New Watch
  * Tap green Edit button
  * Tap +, then scroll and tap 3d
  * Select a built-in 3D model to add to watchface
{{::3d_1.jpg?400|}}
  * You can now move this 3d object how you would normally by dragging or using values in editor, e.g. Position X/Y
  * Note you can now move along the Z axis and scale the object along all 3 axes - Scale X/Y/Z

===== Custom 3D objects =====
  * Custom 3D objects must be in .obj (Wavefront) format
  * You can download ready-made 3D objects from websites such as [[https://blendswap.com|blendswap]] or [[https://free3d.com/3d-models/obj|Free3d]]
  * Try and select low-poly models as these will be displayed on a small watchface with limited memory!
  * Copy the .obj (3D object) file and associated .mtl (material) file, plus associated textures to somewhere on your PC or Mac
  * If you only have .blend format, you need to install Blender using link below and export as .obj (Wavefront format)
  * Alternatively create your own 3D object using Blender and export as .obj (Wavefront format)
  * To add to your watchface click + 3D / Custom
  * Copy your 3D files from your PC/Mac to the directory on your phone specified - this must include .obj (3D object) file and associated .mtl (material) file, plus associated textures
  * Click + 3d / Custom again and you should see your 3D model in the list!


===== How can I get a free 3D Modelling Tool =====
  * We recommend using Blender - free for PC or Mac
  * Download a free 3D tool for PC or Mac such as [[https://www.blender.org/download|Blender]] 
  * Use the 1000s of tutorials online to create your first 3D object


===== Custom 3D objects limitations =====
  * Please download or create low-poly models as these will be displayed on a small watchface with limited memory!
  * Maximum file size of .obj file in WatchMaker is 3MB
  * .obj file names must contain upper case, lower case, numbers, hyphens or underscores only


===== Add 3D Text =====
  * You can add 3D text using the + 3D / Text option
  * Select from one of 3 built-in 3D fonts
  * To increase/decrease the 3d effect, scale the Z axis (with constraints turned off)
  * Support for custom 3D fonts coming soon


===== Add 3D Camera =====
  * Your watchface already has a 3D camera pre-installed
  * Note the 3D camera only works on 3D layers and does not affect 2D layers
  * To change this camera, add a new 3D camera using + 3D / Camera
  * This replaces the default camera and gives you many options to change the camera position, angle and much more


===== Add 3D Lighting =====
  * Your watchface already has a single 3D point light pre-installed
  * Note the 3D lighting only works on 3D layers and does not affect 2D layers
  * To change this default light, add a new 3D light using + 3D / Light
  * You have many options for all lighting types (directional, point and spot)
  * You can have up to 3 of each types of light in your watchface


===== Things to watch out for =====
  * If you change a custom 3D model by overwriting files on your phone, you will need to restart the app to see the changes as 3D models are cached
  * If you export a 3D model and cannot see any colors, you may need to check you have included UV Maps in Blender (check the .obj file has vt elements after export)
  * 2D and 3D objects are rendered separately and do not interact other than respecting their layer order
  * 2D objects do not respond to 3D cameras or lighting
