Heya,
my Unity 2018 4.9f1 sadly doesn’t have the option to apply changes i make to a texture.
I recently updated from 2017 to 2018 with opening my 2017 project (a copy of it) in 2018.
But sadly i can’t crunch compress for example.
Push, anyone? 
Can you try different Unity version? At leas you will know, if problem is with other or just this Unity version.
Hi @Antypodish
Yes, i tried other unity versions already, it works perfectly fine in other versions.
Also in a new project too. So there might be something in my main project which makes it bug out?
My Console doesn’t help at all sadly.
It could be the case.
But try copy / export your game assets to other new project.
Hopefully that should fixed.
Always remember about backups / repo.
@Antypodish that’s exactly what i did, i did that two times.
- I opened a copy of my 2017 project with 2018 and let 2018 upgrade it.
- i made a new project and copied everything from my 2017 project assets folder in the new 2018 empty assets folder.
Both with the same outcome, no available apply button for texture changes. So far that’s even the only problem i have.
What texture file type these are? PNG, JPG, PSD, or other?
Does that texture imported in new clean project works correctly?
Also, did you literal copied files between folder? Or did you use export / import to / from package?
The last step may, or may not necessarily help. But worth give a try.
Sorry for the late reply.
A fresh project works perfectly, any kind of picture is affected.
The problem with exporting is as I know unity it will crash when making a package out of my 38gb project.
I did a copy and paste from the old asset folder in the new clean one and I upgraded a copy of my project using unity 2018, both with the same outcome
Split into smaller packages.
Did that, same result sadly.
2019.2 version. the solution w found was that it was a plugin messing things up. (PSD layout tool) was overriding the UI so I would suggest removing plugins one by one to see if it fixes it
