- Creating character models
There are many different models and characters that are available. The scene comes loaded with the female base model by default. You can add more characters and models to the scene by selecting the button in the top left, and selecting a model. There are different categories of model in selectable tabs along the top.
Transform tools are tools that allow you to manipulate objects (models or props) in the scene. They can be thought of as different modes of interacting with the scene. They can be found at the bottom right corner of the screen. Once a gizmo is selected you can select a joint or object by clicking it. Right clicking or clicking away will deselect that joint or object.
This tool allows you to rotate any joint on a character model into the desired position. This is used to posing the models and rotating props. It is the mode that is active by default and can be re-activated by selecting the button or using the shortcut
Q. You can select and drag an individual axis (the coloured circles) or free rotate by selecting anywhere inside the sphere and dragging.
This tool allows you to move a character model or prop around the scene. Activate it by selecting the button or using the shortcut
W. You can select and drag an axis to move it on one axis, or select the square to move it along a plane (2 axis).
This tool allows you to scale a character model or prop. Activate it by selecting the button or using the shortcut
E. You can select and drag an axis to scale it along just that axis. Use the semi-transparent squares at the end of each axis to scale the whole model uniformly.
These tabs show up in the left side of the screen when new objects are added to the scene. They have tools specific to those objects in them. You can select the model by clicking the image in the tab.
This will duplicate the object in the scene and create a perfect copy next to it. This is useful for creating multiple props for repetitive constructs (think bars of a prison cell), or for generating multiple characters doing the same thing (think marching soldiers).
This will flip your model horizontally for a perfect mirror image. This is useful for mirroring poses from the pose library (think running).
This will toggle the visibility of the object in scene so you can hide it while not working on them to keep your workspace cleaner. This prevents clutter and accidental manipulation.
This will toggle the ability to modify an object so that your scene is cleaner when working on other elements. It prevents accidental manipulation of models you’re happy with.
This will remove the object from the scene.
The program gives you granular control over the scene lighting intensity, direction and type.
Move light source
There is a yellow sphere in the scene that once selected can be moved around the scene using the move gizmo.
Adjust ambient light
In the settings menu in the top right there is a slider to adjust the ambient light 🔆 intensity. Ambient lighting removes shadows as the intensity increases.
Adjust spot light
In the settings menu in the top right there is a slider to adjust the spot light 💡 intensity. The spot light direction comes from the position of the light soure in the scene. Spot lighting creates shadows as the intensity increases.
In the settings menu in the top right you can enable or disable hard shadows 👤 on the model. Hard shadows give more shadow information. Note that enabling hard shadows may cause lagging on older devices.
These tools give you access to extra functionality in the scene and can all be found in the settings menu in the top right.
🌚 Toggle dark mode gives a dark background and menus for reducing eye-strain.
🖊 Toggling the outline effect disables or enables the dark outline effect on all the objects in scene.
🌐 Toggling this option enables or disables the floor grid in the scene.
Adjust field of view
🎥 This slider allows you to set a more extreme field of view to get more intense perspective in the scene (think giant fist perspective).
Poses are how character models are posed according to the rotation of their joints. When you rotate a models joints you are “posing” that model.
When you’re happy with a pose and want to save it for later use, open the pose menu in the bottom right and click
Save pose. This will save your pose in the cloud and you will see it appear beneath the save button. Giving the pose a category when you save it will group your related poses together in an accordion menu.
You can load that pose by clicking the saved pose.
The pose library has 200+ pre-built poses for you to use. It can be found in the pose menu by selecting the
Pose library tab. Select a character then click the pose in the pose library to apply it to that character.
Hand pose library
There are 20+ pre-built hand poses so that you don’t need to fiddle around with all the niggly little joints on the hands. These can be found in the hand pose menu in the bottom right. Click either
Right to apply that pose to either the left or right hand of the model.
Full scenes with models, props, light settings and perspective info can be saved and revisited at a later time or on another device.
Saved scenes are snapshots of the scene at the time of saving. This is slightly different from, say, Photoshop.
When you’re happy with the layout of your scene you can save it by going to the scenes menu in the bottom right of the screen and clicking
Save scene. The scene name will then appear beneath the save button and can be loaded by clicking it. You can group scenes together using categories when saving. This will create an accordion menu of scenes.
Props are shapes and objects that can be scaled and moved around in scene to illustrate certain things. They can be used to create large backgrounds (think buildings), or smaller foreground objects (think tables or coffee cups).
Open the props menu in the top left corner of the screen and select the shape or object you would like to import into the scene.
Props can also be uploaded by selecting the upload button and selecting
Upload prop. Note that only
.obj files can be uploaded.
Props can be modified using the gizmos in the bottom right corner. The props can be scaled along certain planes, moved around, and rotated according to the specific function of the prop.
Images as props
Images can be uploaded and used as props. Select the upload image button in the top left and select an image from your device to upload. Note that no images larger than 2mb are allowed.
Image props handle transparency so can be used as props (think a picture of a sword as a sword prop). They can also be scaled up and used as a background image to help with perspective.
Attach prop to joint
Tap-and-hold a prop then select a joint on a character to attach that prop to the character joint. This allows you do move and modify the character without having to reposition the prop each time.
There are a few other tools that are useful for setting up a scene.
These two tools work as expected, undoing or redoing the last action. They are available using or in the top left, or using
Place on ground
This tool places the active object on the ground (floor grid). Select the object you want to place on the ground then click the place on ground button in the top right of the screen or using the shortcut
Hide all tools
This tool hides all the joints and active gizmos in the scene so you can observe it without all the clutter. Select the hide tools button in the top right corner or using the shortcut
K to toggle.
This tool locks the camera of the scene in place so as to not accidentally move it if you’ve found the perfect perspective. You can toggle the camera lock using the button in the top right of the screen or using the shortcut
There are multiple ways to export scenes and objects.
To take a screenshot of the scene with transparency open the export menu and click
Take screenshot. This will save the screenshot as a png image.
Export 3D model
To export the selected character as a 3D model open the export menu and click either
Export model as .dae or
Export model as .obj.
Note that full scene 3D model exports are not available just yet. You can currently only export the active character model in the scene.

Creating character models
Characters developed for the JustSketchMe app are a bit tricky and have a few constraints that need to be followed. Here is a working character model which can be used for reference.
- The character model should be exported as a
- Sizing of the character should be in proportion to the example model.
- All joints should be zeroed out in a t-pose.
- This includes hand and thumb joints (again, refer to the example model for reference).
- Joints should follow the Mixamo naming pattern of
mixamorigLeftUpLeg(again, refer to example model).
- There should be no textures on the model (textures are generated in-app)
- The mesh should be one single mesh.
- Max size should be around 2.5mb
- The body should warp naturally in a variety of poses (testable with the pose library)
When creating new characters it may be easier to take the example model, unskinning it and using it’s skeleton as a base. Then all you need to do is translate the joints to the new model and skin/weight paint.
The models can be tested in the developer menu (you’ll be issued a passcode).
In the developer menu select
Test fbx. Note this only works on Chrome for some reason.
