Have you checked your graphics settings?
Try to create a blank scene and import one tree to see how it looks. There could be some map settings or model changes that have happened when you were working and trying out things.
Hello there @bygimenezz
As Elias mentioned, I would check your graphic settings. The other point of taking some assets from your product and putting them into a blank scene to see if the issue continues is also a good plan. This looks kind of like a resolution issue in your graphic settings. Give those a try and respond back here if it’s not resolved and we can look into other possible causes.

I still have the same problem, I have the scability option set to high. The lod is set to low because if I set it to high the object disappears directly.
