How to reproduce:
1. Open the attached project ("case_1169679-Material regression.zip")
2. Open the repro scene ("repro_2019")
3. Notice that the object's side has a ripple effect
4. Select the object's normal map
5. See the ripple effect on the left side of the normal map
6. Open the same project with any 2017.4 or 2018.4 version of Unity
7. Inspect the same normal map and notice that there is no ripple effect in the normal map

Expected results: Normal maps look the same
Actual results: Normal maps look different when using default settings

Reproducible with: 2019.1.0a1, 2019.1.11f1, 2019.2.0b10, 2019.3.0a10
Not reproducible with 2017.4.30f1, 2018.4.4f1

Note:
Setting the normal map's compression to "High Quality" fixes the issue

Resolution Note (fix version 2020.1):

This bug is fixed in 2019.2.16f1, 2019.3.0b10, 2020.1.0a8

The Epic games have attempted to present flawlessness level from each angle in the Fortnite Battle Royale. I like to visit https://safecasinopayments.com/paysafecard-betting/ website to play games. I am simply excited to see that this game has been made extremely gigantic and now it is covering each and every noteworthy detail.
