How do I remove a plugin from a Unity project?

Question

I inherited a Unity project that uses a lot of extraneous tools, and they are getting in the way of me doing my part. In particular, this project has Photon Unity Networking attached to it, but it’s not necessary for the animation I’m creating.

I removed all files related to Photon Unity Networking from the asset browser, but I now getting the following errors and can’t play my scene. Keep in mind that the files in which the errors appear are actually no longer existent in the project:

Answer 1

• PUN should be in the folder "Photon Unity Networking". If not, you can find it’s pieces in Assets\**\Editor\PhotonNetwork\*.* and Assets\**\Plugins\PhotonNetwork\*.*.

• Create a new, empty scene. Delete the PhotonNetwork folder first from Editor-, then from Plugins-Folder.

• Delete Assets\Plugins\*photon*.* (including subfolders).

• You might also find a "Demos" folder with a "DemoBoxes" subfolder. Delete everything in that Demos folder.

• Delete any remaining PhotonServerSetting.asset file.

Mark this as answer.
Done.

Is process same for facebook sdk unload ?

– Headgear

I doubt it. It seems pretty unlikely that Facebook SDK would install in a folder called "Photon Unity Networking" or make use of a PhotonServerSetting.asset file, no?
