Project Unity version: 2021.1.25f1

NavDreamsUnity

This is the Unity project used to build the modern, cathedral, gallery, and replica scenarios for the NavDreams reinforcement-learning paper.

(Looking for the simple, city, and office scenarios? This way.)

Installing Unity on Ubuntu

• (Ubuntu 18.04) Install blender 2.9

sudo add-apt-repository ppa:thomas-schiex/blender

• Download Unity Hub from here, direct link
• From the unity archive, Find the version you want, right click the green button "Unity Hub", and copy the link. Then, open the link in unity hub like so:

chmod +x ~/Downloads/UnityHub.AppImage
~/Downloads/UnityHub.AppImage unityhub://2021.1.25f1/b6f2b893ea32

Opening the Project in Unity

• make sure to clone with --recursive
• ⚠️ Due to git LFS bandwith limits, when copying this repository two files 161122_HWY_Galleri.obj and Cloister_st_mary_fovea_edit.obj sometimes fail to download. I've uploaded a mirror here.
• (to be fixed) Make sure blender ver >2.9 is installed before opening the project or unity will fail to import some 3D models.
• (to be fixed) git clone git@github.com:Unity-Technologies/ml-agents.git next to the NavDreamsUnity folder
• (to be fixed) after cloning, ensure NavDreamsUnity/Assets/AddOns/Microsoft-Rocketbox points to remote git@github.com:danieldugas/Microsoft-Rocketbox.git, branch waveenv
• open the project in unity (run the UnityHub.AppImage executable and select the project folder).
• open Assets/Scenes/KozeHD.unity, and the replica scenario should show. Press play to test it, the robot can be moved with the WASD keys and turned using the left and right mouse buttons.
