Model railway apron with overhead passage. Elements of the model are multiplied in the instance mode previously reset with the help of Reset XForm. For convenience the same type of elements are combined into groups. The model is partially under smoothing (you can not use it but in order to avoid unnecessary angularities it is better to use a modifier). These objects have the prefix turbo. Smoothing is performed by the method of smoothing groups so put the appropriate checkbox in the turbosmooth modifier. And when importing an FBX file we also tick off the import point for smoothing groups. Also in order to avoid creating additional materials some objects in the properties were assigned an Object ID for the G-Buffer. This data is present in the name of the elements in order to restore it if the model was imported from the FBX file. A simplified material was created for exporting to the FBX file since Because of the composite materials errors could have occurred when importing into a new scene. Therefore when opening FBX in a new scene we immediately add the full material. The full material file and all textures naturally lie next to the model in the archive. If necessary you may have to correct the paths to the textures through Asset Tracking.
