Hey guys, thanks for the input, glad that you are interested.
@jojo8026 We could implement the feature that you can use any road assets, but only for the road segments. The intersections are procedurally generated, so you can only apply materials to the generated mesh. Although we could enable deforming the provided intersection asset such that it fits the procedural geometry (in similar way as it is done for road segments), but I am no sure if that is going to provide acceptable results.
You may additional give some thought to the idea that, with this tool, you can procedurally create any desired road asset with the elements that you actually need (as you seen in the demo, you can easily place sidewalks, rails guards, curbstones, manholes, lane markings, buildings, road signs and etc.) and then just apply materials… That means instead of buying different assets you can automatically create a highly diverse road networks - as is if you have bought many different assets. On the other hand, I understand that you might want to just quickly import existing assets and start level designing - as I said, we can easily implement that for the road segments.
