If you loaded your sculpt from disk, Save option resaves your work under the last specified filename, in the same directory. However, if this is the first time you’re saving, the Save Sculpt panel opens:
-
Use the keyboard to name the file.- Use either hand to point at keys on the keyboard.
- Squeeze the trigger on either hand to select (“press”) a key.
You can position the cursor by pointing and squeezing at a location inside the filename, or use any of the special keys on the keyboard:
- Arrow - deletes a character.
- Clear - clears the entire name.
- Enter - saves your sculpt with the specified filename.
- +1 - increments the last digit in the filename. If the filename does not end in a number, a “1” is added (and can be incremented by repeating the gesture).
Once you’ve saved your work (or if you’re working on previous sculpt that you’ve loaded into Medium), the Quick Save option saves the sculpt with the previously specified filename in its original directory.
Note:
The Quick Save option overwrites your previous work; earlier versions are not preserved. If you want to save a new version, use the Save As command.
Loads a previously saved sculpt from your local file system. When you choose Load, the Load Sculpt panel opens:
Loads a .fbx or .obj file from your local file system into Medium as clay. When you choose Add Mesh as Clay, the added mesh appears in addition to your existing sculpt. (You have the op on when adding to specify that the imported mesh should appear as a new layer).
When you choose Add Mesh as Clay, the Add Mesh panel opens. To load a mesh as clay:
Loads an existing Medium sculpt into your current sculpting session. Importing a sculpt will bring over all layers, meshes, images, lights, and transform nodes under a new transform parent that is named after the imported file.
When you choose Add Sculpt, the Add Sculpt panel opens. To load a sculpt to your scene:
Exports the current scene to your local file system in a non-Medium format (such as .obj or .fbx). In this section, you’ll learn:
After you’ve created your perfect sculpt, you may want to export it, either to move it along in your production pipeline, or perhaps for 3D printing.
To export your sculpt:
-
Export menu.Triangle Count: Initially, this shows the number of triangles that the current sculpt would generate when exported as a mesh. You can optionally reduce the number of triangles to export:
- Select one of the presets (0.1, 1.0, 10.0 or 100.0) to perform a shortcut percentage decimation.
- Drag the handle on the slider left and right to select a specific number of triangles.
You can use either option (or a combination of both) to reach your target number of triangles for export.
Presets: The preset buttons will change all the export settings to suggested settings for common use-cases like Real-Time or 3D printing. This is a good starting point and you can customize the parameters afterwards.
Color Data: You have two different ways to exported color information with your sculpt:
- Vertex color - a color value is assigned to each vertex on the exported mesh. No image files are generated when exporting a sculpt using vertex color.
- Textures - the mesh is “unfolded” onto a 2D image; the color information for each triangle on the sculpt is represented by a small piece of a texture map (image file). If you choose Textures, the menu expands to show more options (see Exporting Texture Information below).
Output File Format
Select the output file format option needed for your pipeline:
- .obj
- .fbx
By default, all files, include meshes and textures, are saved in the following folder of your Medium library:
C:\Users\<username>\Documents\Medium\Exports\<username>
However, you are free to navigate to a different location (including your favorites) using the file selector to save your exported content anywhere on your computer's local filing system.
Texture Size: If you include textures as part of your export, you can optionally set the size of the exported image. Keep in mind to use a large enough image to support the number of triangles in your mesh. Using a texture map that is too small can cause a loss of texture detail in your export.
However, if your production pipeline dictates that a given object can only carry texture data of a certain size, you can use the presets (256, 512, 1024, 2048, 4096, and 8192) to export a map of those dimensions. For example, selecting 1024 exports a texture map 1024 pixels wide x 1024 pixels tall.
To export full texture data, deselect any of the presets.
Note:
PNG files save normal maps at a higher fidelity than TGA files. (PNG normal maps use 16 bits / channel, which avoids banding. Medium supports TGA normal maps for broad compatibility, but they use only 8 bits / channel.)
You can take photos to share your progress with someone who’s reviewing your work, or to post for your friends on social media. You’ll want to select the point of view for the camera, and you’ll be able to preview what your picture will look like in a rectangular viewfinder.
Starting the Camera
To start your camera:
The Capture menu opens next to your Support hand and stays there as long as you’re capturing. A viewfinder also opens, attached to your Support hand by default. (You can also attach the camera to your avatar’s head or position it at a specific place in the scene, as described below).
There are two ways to take a photo:
FOV
Drag the handle on the Field of Vision slider to adjust the focal length of your camera’s lens. This is similar to zooming in and out with an adjustable camera lens.
Note:
Extreme settings can add curvature to your photos (just like a real camera lens). A value of around 50 corresponds roughly to a ‘natural’ human view.
Positioning the Camera
Select one of the following POVs:
- Hand: attaches the camera to your Support hand. The viewfinder follows the position of your Support hand and you can preview the photo in the viewfinder.
- Head: attaches the camera to your head, and shows a preview of the photo in a small rectangle attached to the upper right corner of the photo menu. You take photos from your avatar’s point of view.
- World: positions the camera at a specific static location in your scene (a good option if you want to take photos of several consecutive steps from the same angle).
- Transform Manipulator: to change the location of the camera in World mode, select the manipulator tool (next to the world icon). With this option selected, squeeze the Support hand trigger to move the viewfinder instead of your sculpt.
What’s Saved and Where?
Photos are saved as .png files in the following directory:
C:\Users\<username>\Documents\Medium\Photos\<username>
You can take videos to show how a specific sculpting technique, or to post for your friends on social media. You’ll want to select the point of view for the camera, and you’ll be able to preview what your picture will look like in a rectangular viewfinder.
Starting the Camera
To start your camera:
The Capture menu opens over your Support hand and stays there as long as you’re capturing.
A viewfinder also opens, attached to your Support hand by default. (You can also attach the camera to your avatar’s head or position it at a specific place in the scene, as described below).
To take a video:
FOV (Field of View)
Drag the handle on the Field of View slider to adjust the focal length of your camera’s lens. This is similar to zooming in and out with an adjustable camera lens.
Note:
Extreme settings can add curvature to your photos (just like a real camera lens).
Positioning the Camera
Select one of the following points of view (POVs):
- Hand: attaches the camera to your Support hand. The viewfinder follows the position of your Support hand and you can preview the photo in the viewfinder.
- Head: attaches the camera to your head, and shows a preview of the photo in a small rectangle attached to the upper right corner of the photo menu. You take photos from your avatar’s point of view.
- World: positions the camera at a specific static location in your scene (a good option if you want to take photos of several consecutive steps from the same angle).
- Transform Manipulator: to change the location of the camera in World mode, select the manipulator tool (next to the world icon). With this option selected, squeeze the Support hand grip button to reposition the viewfinder (instead of moving your sculpt).
Desktop Preview
If Desktop Preview is on, the capture view will display in the Desktop Preview Window. This is useful if you are giving a live demo/presentation and you want a camera that doesn’t move with your head, or if you want to capture or stream from your desktop instead of VR.
Stop Recording and Exit
- To stop recording, select the stop icon at the bottom of the capture menu.
- To exit from capture mode, select the X on the upper left corner of the capture menu.
What’s Saved and Where?
Videos are saved as .mp4 files in the following folder:
C:\Users\<username>\Documents\Medium\Videos\<user>
You can load videos view them right alongside your current work and view them from any angle. To load a video or VR session:
Note:
Videos will pause if you remove your headset, so you can take a break and then pick up where you left off.
Use the Share option in the Control Panel to share your work to any of the following locations:
- Oculus Home — share your sculpt as an object you can place in your Oculus home.
Share Sculpt to Home…
The Share to Home option generates an object that you can place in your Oculus Home environment. In the Share to Home dialog, you’ll see a 3D preview of your object, along with its title (if you’ve previously named the sculpt. You can also click the ellipsis (“...”) if you want to change the name before exporting:
Detail: Depending on the type of object you’re sending to your Oculus Home, choose either Low or High level of detail. For common objects like a ball or a coffee mug, choose Low, but for characters choose High. You can set the relative size for your sculpt by editing the Export Origin in the Scene Graph.
Inside Oculus Home, you’ll find your exported objects in the My Objects folder on the objects menu.
If you are online with Oculus, and a friend sends you an invitation to Studio Share, a tone is heard on your headset:
- Accept the invitation:if you want to enter a Studio Share session.
- Ignore the invitation: if you’re busy and don’t want to Studio Share at the moment.
Once you accept the invitation, you can begin working together.
Once you have sent an invitation and your friend has accepted, you’ll see both avatars in your scene. You can talk to each other, move around each other’s sculpts, and work in a highly communal fashion.
Note:
While you can sculpt simultaneously, you can’t sculpt on each other’s work.
- Double Press Speed: Some actions (such as opening the Settings menu) are enabled with the double tap of a button. This sets the maximum time in which two quick taps are recognized as a double tap gesture. If you are double tapping on a button but not seeing the expected menu, you may want to increase this value:
- Use a lower value if you’re quick on the draw.
- Use a higher value if you work at a more relaxed pace.
- Tool Tips: Shows Tool Tips when you hover over a menu option in Medium.
- Application sounds: Enables sounds for actions in Medium.
- Controller vibration: Vibrates the controllers to alert the artist to certain events (such as a successful save).
- Avatar Hands: Displays your Oculus Avatar hands in the scene. If not selected, only the tools are displayed.
- Setting Handedness: Defines which hand is your Tool hand. Most users select their dominant hand (so if you are right handed, select the right).
