Hello,
After i imported an asset from the store unity told me if you wanna fix or update some scripts (not sure of what it does) however i pressed yes, after the import finished i got some errors and i lost scene view on the active scene which is my main scene. i can see nothing on the scene tab now,
but scene tab on other scene still work just fine.
and this was the asset i ve imported :
Please i need help ,
PS : Feel free to criticize my level design 
Hello @unity_88AbgLG5ZimeZw ,
Is this also happening if you import the plugin from an empty project?
If so, you can ask directly to the developer here: https://www.matkovskidragos.com/
Otherwise, you can narrow your search by adding little by little your stuff to the mentioned empty project 
Good luck with it!
Thank you @DiegoDePalacio_1 for you return
I narrowed my search by disabling little by little gameobjects on my scene and it turn out the the prefab first person controller i ve imported originaly from the famous standard asset got modified by newly imported asset named IL3DN, (probably because IL3DN used that same FPS controller on his scene) and added automatically a second post processing component on top my current one.

so by deleting the second post processing component scene view start working again
So i think if u share a same prefab with an asset you want to import. unity will ask if you want to update yours to match the on you want to import ?
Because i ve noticed that also the script of the FPS controller prefab has changed to a script used on that IL3DN asset
Thanks for your support

Hi @unity_88AbgLG5ZimeZw ,
I’m glad that you found it!
On the other hand, I’m not familiarized with such an asset store plugin, but more likely what you’re describing is probably happening inside of one IL3DN’s AssetPostprocessor class.
If you’re interested, you can find more information about it here: Unity - Scripting API: AssetPostprocessor
Good luck with your project!
