Here for the next points......
How you can see in the attached pics, when you create the gantry blueprint for your 3D file just exported, it necessary to set up the node as in the image.
So, when you have your exported 3D file with texture:
- copy it into the "source" folder inside your Railworks directory (if you didn't have this folder, create it)
- oper the blueprint.exe
- goto your source folder/provider/product and find the 3D file
- there, create a new gentry blueprint
- set this blueprint with the needed information
- set up the node (as you can see in the image)
- export the file
Hope this is helpful, in any case, I'm here!
