Installing RealityScan and Blender

Prerequisites:

1. Make an account with Epic Games (https://www.unrealengine.com/id/login).

   • Take at least 20 pictures.
   • It’ll process the pictures as you take them.
   • Press the blue → when you’re done.
4. Crop your imagine down to size, you’ll want to have the lowest amount of polygons as possible.
5. Name your model and press “Process Now”
6. It’ll usually take awhile for the model to process (More pictures → more time).

Getting Access to your Model

1. You can either share on sketchfab(requires a sketchfab account) or export it as a 3D model.
   • Sketchfab (You only have ~30 uploads per month)
     • Press “Share on Sketchfab” and give it a title.
     • You can choose to add more attributes to it but they’re not necessary.
     • Press “Share on Sketchfab”.
   • Export 3D Model
     • Find a way to access your .obj file (Ex: Google Drive).

   • Go to your Sketchfab account picture in the top right of the website and go to “Models”.
   • Select your model.
   • Scroll down to and select “Download 3D Model”, it should be right beneath your profile picture and name.
   • Download it as a .obj file.

Converting your Model

1. In your downloads folder there’ll be a (MODELNAME).zip, unzip this and go to (MODELNAME)/source and unzip shareModel.zip.
   • Don’t close this folder.
2. Converting from .obj to .fbx
   • Launch Blender and under “New File”, select General.
   • Delete the pregenerated cube.
   • Go to File > Import > Wavefront (.obj).
   • Once it’s loaded, go to File > Export > FBX (.fbx).
