@MaSe87 You have some very nice insights. The Fernbus tool is very interesting thanks for pointing me to that. We have the quit similar features in our tool, and we could make the same workflow as they - we will definitely think more about that. In contrast to Fernbus tool, we have procedural intersection generation which is much more flexible than just importing pre-made intersection patterns. Regarding the UV-mapping issues we have some ideas which for now function quite well, but on the other hand, most of the “texturing” is done by placing lane, crosswalk, manhole objects on the road, so the UVs are needed only for the the road surface texture. Later, after finishing the road network design, we could project the placed lanes and etc to a texture with a proper corresponding UV map to make stuff work faster in cases where the roads and intersections remain static during the application runtime.
