only workaround I can think of is create specifically assets that transition from -0.1 to -0.3 that would be used on super short segments (although long enough for pathfinding to work) between different road standards, but it won't be that easy either + seems soo overkilled I doubt anyone would use it

@Benskian yes, the real issue is connection to the 0.3m roads but transition nodes do not work that way. Transition nodes are used for example in vanilla highways - mesh slopes downwards, as highways are on 0m, to meet with -0.3m sunken roads. The key issue is that transition nodes are used in this exact scenario of one road CATEGORY transitioning to other DEFINED in the assets. It just wouldn't work, either my roads wouldn't match others assets (like it is now) or wouldn't match themselves (and potentially other non-0.3 standard).

Can't blame CO for transition node flag coding, seems reasonable enough, although we definietely can blame them for ugly 0.3 road standard.

I can confirm that the pedestrian behaviour in-game is as you describe. This is very useful for creating functional custom paths around these roads. Kudos for your attention to detail!

On that note, the key issue with the roads isn't really the 0.1m elevation itself but just the clipping that occurs when these road networks connect to other standard 0.3m elevation roads (which I am sure also irks you).

I know nothing about asset creation in C:S, but I assume that it should be possible to create a "transition node" mesh that slopes from 0.1m to 0.3m so that the road surface slopes between different networks at intersections instead of clipping (similar to vanilla highway networks).

If it is possible to address this issue, I think it would make these networks truly excellent assets that many players would greatly appreciate. Best of luck with your future projects!

@Benskin thank you! Actually, I haven't removed the ped lanes on the left side of the road (which would appear in the inside of a right hand drive roundabout) for a left hand driving compatibility. Only the ped lanes have super low speed limit which actually influences pathfinding (despite peds not being able to reach even that low speed) and it makes them prefer custom paths built just by the side of the road.

Well, I really don't want to sit again through all of these so very unlikely I will remake any; I will only expand the pack

I've been searching for a good-quality, narrow, multi-lane road network to create small roundabouts and these series of roads work perfectly as they don't create crosswalks and don't put footpaths on the inside of the roundabout. Thank you so much for creating these!

The only caveat, unfortunately, is the non-standard elevation. Would it be at all possible to create a version of these roads with standard the standard road elevation (at the very least for the 1, 2 and 3 lane versions)? Thanks again!
