well this exterior is one of the series of 6 exteriors i created in blender!
I had this vision in mind to make a living between nature, more like color of flowers, freshness of grass but also with simplicity in structure!
So i used all my own made nature asset pack.
All flowers n grass..
Made BMW in blender for exteriors!
I rendered 2 styles:
1) Render with sunlight
2) Evening Light with mild clouds and white or warm interior lights
Also Made B&W Classic Black strips renders!
All done in blender 2.79b
cycles rendering engine!
