Navigation and Controls :
You can navigate in Orbit Mode and First Person Mode.
Orbit Mode (default): rotate around a fixed camera point
First Person: walk through space and look around
Clicking Settings in the bottom-right corner of the 3D viewer shows the available Navigation options for the model. They depend on the 3D Settings.
For more details on switching between them, see Interface and Options. For VR mode, see Virtual Reality.
Orbit Mode
Move camera: 1 finger drag or Left Mouse Button
Pan: 2-finger drag or Right Mouse Button or SHIFT+ Left Mouse Button
Zoom on object: Double-tap or Double-click on object
Zoom out: Double-tap or Double-click on background
Zoom: Pinch in/out or Mousewheel or CTRL + Left Mouse Button
Double-clicking the background will re-center the model and set the camera pivot point to the middle of its bounding box.
Double-clicking anywhere on the model sets the camera pivot point to that spot. It also works for individual Annotation views.
First Person:
Move: ↑,←,↓,→ (or W,A,S,D)
Look around: 1-finger drag or Left Mouse Button
Adjust speed: Mousewheel
Rendering Settings
Default: 1
Shadeless: 2
MatCap: 3
Wireframe: 5
Lighting:
Rotate all lighting: 3-finger drag (on mobile) or ALT + Left Mouse Button
Rotate environment only: ALT + SHIFT + Left Mouse Button
Rotate real-time lights only: ALT + CONTROL + Left Mouse Button
Lights attached to the camera will not rotate.
Annotations:
Previous: J or PageUp

Animations
Previous frame: B or CTRL+B or SHIFT+B
Next frame: N or CTRL+N or SHIFT+N
Go to time/frame : ENTER
Help:
Clicking the Help icon shows you the available viewer controls and allows you to reset the camera.
Settings > Textures:
Set max texture resolution. We automatically choose the best setting for performance and quality on your device and GPU. If multi-resolution textures have not been generated yet, this option may not be available. We will not show options lower than your device's default.
View in VR:
Click View in VR to see your model in virtual reality.
Fullscreen:
Opens the viewer in fullscreen mode. You can also press the F key to do this.
Animation:
Click Play/Pause to toggle playback. Press Enter to focus the timestamp text field, enter a specific time or frame, and press Enter again to go to that time or frame.
Click and drag the cursor on the timeline ("scrub") to go to that moment. If the animation is playing, it will play from that moment. If the animation is paused, it will stay paused at this moment. Scrolling while hovering on the timeline also scrubs.
Animation options are available in the animation menu next to the timestamp.
You can view Bones and Bone Weights in animated, rigged models. The keyboard shortcut is 6.
View different animation takes or the Static Pose by clicking the animation name. You can set the default animation and animation order in Animation Settings.
Change the cycle type:
One: loop the current animation
All: loop through all available animations
None: play all the available animations then stop
Change the animation speed:
x0.1: slow the animation by 10
x0.5: slow the animation by 2
x1: restore the normal speed
x2: speed up the animation by 2
Model Inspector:
The Model Inspector allows you to study details about a model's geometry, topology, materials, and textures. Activate it by clicking/tapping the button in the bottom right of the viewer or pressing the I key.
Single Sided:
You can toggle "Single Sided" to view only the front face of meshes. This is the same as the single sided rendering option in material settings.
Wireframe:
The wireframe view lets you see the mesh's topology (triangles, quads, n-Gons). The keyboard shortcut is 5. If you'd like, you can choose a color from the Model Inspector menu.
Viewport:
You can choose between showing a 3D view of the model, a 2D view of the selected texture, or both side by side.
When viewing 3D+2D, there will be feedback on your cursor showing the position in both views.
Render:
Final Render and No Post-Processing allow you to enable or disable Post-processing filters. The keyboard shortcut is 1.
Materials:
You can inspect each material channel that's active on the model (base color, normal map, etc.). The keyboard shortcut is 2.
If you're using 3D+2D or 2D mode and the model has more than one material, you can choose a material in the scene by clicking/tapping it in the viewer or from the drop-down menu in the top-right. If a model has more than one UV set, you can also switch between them from the drop-down menu.
Geometry:
You can enable MatCap mode and MatCap + Surface (if the material has a normap map), as well as show the blank Geometry to better inspect the wireframe, and display vertex normals. The keyboard shortcut to toggle through them is 3 but you can combine the views together with MatCap (3) and Wireframe (5).
UV:
The UV Checker lets you inspect the model's UVs using a sample grid texture. The UV Checker is only available if the model uses a texture. The keyboard shortcut is 4.
