how to import environment package in unity 2018

Please help , i want to import packages like camera , environment ,2d as were in unity 2015. Currently i have unity 2018.

 

I have a similar issue, I was watching a tutorial video about the terrain editor in Unity 2018.3 and the speaker says to go to Assets > Import Package > Environment. But under the Import Asset drop down menu, it only says 'Custom Package...'

I thought that by downloading the "Unity standard asset package" that it would fix this lack of options, but still nothing.

So, clearly, we are both doing something wrong between the download/import phase to not see the packages, right?

Try something as this
(1) https://docs.unity3d.com/Manual/CreatingEnvironments.html
to
(2) https://assetstore.unity.com/packag...257.271736646.1646692614-599315393.1646354646
.
I think it means the new standard form to do something like you need.
!!!but actually, it (2) doesn't work very well, it contains only brushes and masks. Try another one or something else.
