Changing the Temp directory location

Unity is having a hard time building some jobs in Jenkins CI because the Temp directory in the root of the project folder is read only. It is read only because it is inheriting permissions from the project folder which is RO due to it being checked into Perforce.

So my question is: Is there any way to change the location of the Temp directory to something more appropriate (like /tmp)? Is there a CLI parameter or setting in the editor itself?

 

Anyone ever reply? I am searching for this answer as well right now, 4 years later haha

 

You can change the location of your lighting cache, which can bloat up into the gigabytes when generating scene lighting. It's in Edit>Preferences>GI Cache. Before you change the cache location, make sure to hit 'Clean Cache' so you don't leave the bloated old directory there. Then hit 'Custom cache location' and browse for your directory.
