For your information, I released yesterday 67 new 3D models for the French Forensic Police Office designed by Carlos Folch, the author of Resources.blogscopia.
As shown in the following image, they contain a few items for animals, some heaps, various traces, a new car, some vehicle parts and a whole collection of railroad and road models used by the Forensic Police to reproduce accident scenes.
As explained in the new Road models guide (PDF - 9.6 MB - in French but with many images), the road parts use different materials that the user may hide with the Material modification dialog box to get various configurations, with or without sidewalks, security rails, continuous or dashed lines...
Even if this may not match the first goal of Sweet Home 3D, I hope you will like these new models and find them useful.
