Hello, thank you all for your comments, it makes me very happy!
fantozzi : I think this bottle will be fine! But it is better to wait until the SNT is on exchanges before drinking, otherwise I will be inefficient!
Kitsune : I already tried with this software, the small problem is that the textures appear randomly in the LE. That is to say that it does not go in the order that I want. Unless I used it badly ...

Here are the changes I made for all SNT networks (this is only an example with Maxis road) :

There have been some changes made to all networks:
- Green logos to categorize and sort each type of textures (useful in the LE).
- Now, two options are available to you; yellow or white pedestrian crossing (european standard).
- Pedestrian crossings are no longer only available for straight roads and intersections, but also for turns and parkings.
- The road markings of turns with crossroad have been modified for more realism.See you soon!
