Q: When I’m painting or sculpting, sometimes the surface looks jagged or pixelated. How do I make it smoother and sharper?
A: By increasing the resolution of the layer you’re working on, you can increase detail and precision. To do this, pull back on the support hand thumbstick, select the layer you would like to increase resolution on, then select the desired resolution. After a brief processing period, your layer will now appear at a higher resolution and allow finer details for both sculpting and painting.
Q: I tried to increase the resolution on my layer and part of my sculpt got cut off or disappeared. What happened?
A: When the resolution increases, the bounding box of the layer scales down; anything outside of the bounding box when it scales will be cut off. To resolve this issue, undo the resolution increase operation and choose “Center” before once again increasing the resolution.
Q: What’s the little triangle on my tool tray? Why does my tool switch when I pull the support hand trigger?
A: This is your Alt tool—think of it like a shortcut to switch from one tool to another with a click of the trigger. Your default Alt tool is Smooth. If you’re sculpting clay and want to quickly smooth out an edge, press and hold the front trigger on the support controller to switch to the Smooth tool. The primary controller’s functions will work as expected—thumbstick for size and color wheel, front trigger for use—as long as the support controller’s trigger is held down. To choose another Alt tool, hover over the desired tool with your primary hand and press the support controller’s front trigger. The triangle will move to indicate your selection.
Q: When I try to upload assets to the sharing site and take my HMD off to change the settings, the upload fails. How do I fix this problem?
A: Your HMD must remain on during the upload. Make sure the HMD remains active until you receive the upload complete notification.
Q: Can I convert my recording into another video format?
A: Recordings aren’t actually a video. They are a special VR-only format for use in Oculus Medium. We will be adding video export support in a later update.
Q: Can I import my own OBJ/FBX files into Medium to work with?
A: Yes! You can import OBJ and FBX files as either stamps or reference meshes. Once they're in as reference meshes you can then select them and choose the "convert to clay" option which will convert them to the Medium file format and you'll be able to work on them however you'd like!
Q: Are there limitations to what I can import as a stamp?
A: You can import any OBJ or FBX; however, you should be aware that stamps are at a lower resolution than the sculpts as they are meant to be used as tools. In addition, any OBJs intended for import need to be closed or else they will not behave properly once they are brought into Medium.
Q: What exactly does the Export button in the home menu do?
A: The Export button exports a high-resolution version of your sculpt. To be very specific, you now get two .obj files. Let's say your Sculpt is called "fork". You'll have a "fork.obj", which is the high-res version, and a "fork_preview.obj", which is low-res.
Q: Is there a poly limit on performance? Is there a way to check or monitor performance when I have multiple layers?
A: We currently don't have a built-in way to show you the performance or memory footprint. For best performance, a good NVIDIA GPU will do the trick (a GTX 1080 is excellent). Our optimization work for Medium is ongoing. We currently have a 20-layer limit; when you get close to running out of physical memory (layers or otherwise), you’ll receive a pop-up warning. If you continue to use more memory after that, Windows will start swapping memory pages back and forth from disk, which will negatively impact performance.
Q: Does performance increase if I split a complicated model into separate layers?
A: No. The number of layers does not affect performance. We did a lot of work to ensure that performance is dependent upon the total amount of polygons you’re rendering across all layers. If you split up the sculpt so that one layer is high-resolution while the others are low-resolution, you can manage the total number of polygons to increase performance overall.
Q: How many levels of resolution are there?
A: This depends on how much physical memory you have available on your system—we let you increase the resolution of a layer as many times as your machine can handle (Medium 1.0, 32 GB of RAM or better will help a lot). We’re working on memory usage improvements, which will be rolled out in future releases.
Q: Sometimes when I use the Cut tool, it makes a failure sound and doesn’t cut. What’s going on?
A: The Cut tool has to completely sever whatever you’re trying to cut, so when you’re making cuts, make sure the blue line from the tool passes all the way through solid material.

Hi, this tool has great potential. And I appreciate that it is suggesting you are working with clay. But is there any chance to get to forget that "clay" Thing for a moment ? I mean when I import a clean 3D model of a car in .obj format, I would love to have it smooth & clean instead of having it modified to appear to have been handcrafted (slightly clumsily) with rough edges and small holes and the rest of it.
It would just be such a great creative tool ! And looking at some of the tools available under e.g. 3DMax, there are a couple of tools which would really lift it even higher up the creative tools ladder if being implemented...
Or is this where Oculus actually wish to stay out of the path of any "serious" tool makers and only intended this from the start as a proof of concept ?

Is there any visual indication of layer resolution, or can you bring it back down? I seem to be struggling to obtain a model that's as smooth as some of the ones on streams when using hard-edged stamps like the mechanical pieces.

Sculpting is a sub-section of 3-d modelling. In terms of "Serious" tool, I'd say Medium is well on the way to being an industry-leading sculpting package, in terms of usability. All they have to do is add a couple of features and tool controls and it's ready to go up against the industry heavyweights.
If you're importing a finished 3d mesh, like a car, into a sculpting package then you have your whole workflow back to front, IMO.
