Thank you very much!
My Workflow goes like this:
1. Obtain original plans. My main source is the
Architekturmuseum of the Technische Universitaet Berlin.
2. Import the drawing to
Autosketch and scale it to 1:1
3. Create the contours and export them to a DXF
4. Import this to
3dsMax and create the 3d objects, mostly by using the
Extrude function.
5. Then the mapping takes place with biggest seamless textures I can find. Until now I have a collection with about 4,500 files
6. If all the mapping is done I create in a second
Map Channel, a map which is used for the
Render To Texture process I do with
V-Ray
7. Now all the objects are copied to another layer and the new rendered textures are assigned to them and exported to a lod file
8. Copied again to another layer, polygons reduced and so on until I get below 500 polygons
Et voila, a new Trainz asset is born
