This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This the the corrected version of Falkeneck. Fixed the roof, railings, and the moat. Have not done the gutters and downspouts, which the model has. This way you do not have to fix anything. Bob Oct 26 update: Paulwall has an interior in this structure, check it out, it is super!
