Unity5 - Details not showing on terrain in build

Hi.

I'm upgrading an application from a (very) old Unity version (4.1.5 to be precise) to Unity 5. Quite a jump I admit, but overall, process went quite smoothly.
The only problem I'm stuck with right now is that details on my terrain textures don't appear in the build version. I attached two screenshots so that you can see the difference. It's like if it stays at mipmap level 0 instead of updating to the top detailled texture.
I don't know where the problem is, so I'm asking you guys, hoping someone has an explanation and a solution for this problem.

Editor View (correct in Play mode too) :


Result when app is built :


Thanks.

 

I don't have a solution to your issue - but I just wanted to say your UI looks real nice.

Hope you find the answer and solution to your problem.

 

The only thing I can think of is your base map distance setting is extremely low.

 

Thanks KingMatthew for your reply.
I tried changing the base map distance value, but even setting it to the max value didn't change the result.
I also tried building on different Quality settings and Deployment targets (standalone or web) and still the problem remains.
Anyone having another idea ?

 

You could try re importing your textures if you haven't already. Otherwise check the texture settings and see if the resolution is messed up.

 

I had this same problem and fixed it by enabling read/write on the settings of the textures used as details.
