This 3D model was originally created with Sketchup 13 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 I will use it in my mega project. I hope it's well. Also, for the Crowne Springs project..well, it didn't fail, it's just idle for a few moments. There are tons of houses that aren't yet built, so it'll take some time.
