You can import your own 3D models (.obj format) easily into Arkio. Loading of models in Arkio must be done before you start the app by placing the .obj, .mtl and all texture files in the following paths:
Quest\Internal shared storage\Arkio\Import\Models
At the start of Arkio, these files will be converted and once successfully loaded shown in the asset drawer under the last tab.
If you briefly hover the icon the full name of the import will show and clicking the icon will open a sub dialog where you can define the import settings and method of loading your objects. You can place it as a normal Arkio element (right button), or use it as a table reference model (left button).
Note you can set the units for an imported model and the vertical placement (lowest geometry or origin) before placing it in the scene
"Place as object" lets you place the import like any other Arkio 3D elements. Pressing the trigger will show a preview of the object that can be rotated using your thumbstick left/right. When releasing the trigger the object will be placed on that location. Pressing the trigger again will start placing another instance of that object.
Models can also be loaded on the table using the left button. This will resize the table according to the model size and makes the model no longer editable. This is great for context or reference models of cities, buildings or photogrammetry scans that form the base of your new Arkio creations.
Make sure imported models don't exceed 250.000 polygons to avoid crashes on your mobile devices or uncomfortable low framerates in your VR experience, we put together a small workflow to help you prepare your models from Revit using 3DSMax.
- Loading of huge models is not recommended, try to keep your models below 250.000 polygons to avoid crashes and VR performance loss when working with mobile devices or the Oculus Quest.
- Some OBJ exporters might not provide clean obj files and can result in loss of geometry or the files not loading at all.
- If you experience issues loading your models try to load the OBJ exports in Windows 3D viewer, 3DSMax or Rhino to see if the files load well here and what geometry might be causing the issue.
- Depending on your model file size it might take a while for other users in a multi-user session to see your 3D models
- Sometimes imported models get corrupt and affect the loading of other imported files. Temporarily files from loaded 3D models can be cleaned from:
\Quest\Internal shared storage\Arkio\ResourceCache
