Anyway to change project from assetpipline v2 to v1

I got a serious problem of lag on unity when the asset pipline upgrade to v2
Each time I change a minor script causes huge lags on editor over 3-5 seconds.


This bug did not fix on any lastest version but as not too common seems unity team can not reproduce it.
So I have an idea whether there is a way to drop back pipline from v2 to v1 except by the way that I create a project on 2.x then open in 4.3

 

You should just be able to choose to use V1 in Project Settings:

 

You are right.But actually on new versions of unity.There is not an option of that because of deprecated.

 

Oh. Are you on 2020.1? Asset DB V1 was already removed? Or does it just say Deprecated? If it's just that it says Deprecated, that's fine. You can still use it. It says Deprecated for V1 in 2019.4 as well.

 

It says decrepcated if you upgrade a project from v1 to v2.But if you choice v2 or just create a new project in 2020.
There is no option. V2 is a text in setting inspector but not a selectable option.

OK.I mean just fogot it.I can switch to 2017 and finish all the work then switch back to 2020 or 2019.4.7LTS
My really question is why unity not fix the saving lag problem on version which uses asset pipline v2.
This makes me say goodbye to unity.

OK.Thanks for you again.

 

Switching a project from 2020, or 2019, back to 2017 will probably break a whole lot of things, and I would personally not try it unless I had no possible other way forward. That sounds like a good way to introduce a lot of headaches into your workflow.

Anyway, I just checked on 2020.1, and for a new project I see that Asset DB V2 is the only option. Hopefully the issue you're facing gets some traction in the near future.
