If the device you are using isn't compatible with live scans, you can still upload videos to create 3D models
Open the Luma app and click on the + button. If the app doesn't let you scan live, then you will need to upload a video
Setup your space so that the object you are using has space around it for you to walk.
Hold the device vertically and start a video using the device's camera app.
Keep shooting the video as you walk around the object, capturing all sides and its top.
Go back to the Luma app and choose the video you have just taken.
Luma will upload the video and process it using it's AI program.
Wait for the app to notify you that the model is ready.
