MAKE SURE TO SET THE TEXTURE QUALITY TO HD. In your viewer select on Settings and set the texture quality to HD instead of SD to get the maximum resolution.
The day version of a persian garden scene I modeled for my fluid simulation in Unity. I made it with Blender and Substance, you can view my reference board here: https://www.pinterest.de/shshahrabi/persian-garden/
And the night version here: https://skfb.ly/6XX8T
You can download some of the individual stuff in higher resolution with PBR map on my sketchfab.
For the day version I decided not to put any music since afternoons people are always napping and is a vey quite time.
