Hi,
This post is for the benefit of users of our free Road/Path and River Tools.
After testing and some reports from users, it has come to our attention that there are substantial breaking changes in Unity 4 that prevent these tools from working as expected.
Neither the Road/Path Tool or the River Tool are currently supported in Unity 4. It is likely that they will need a complete overhaul and re-release. This is on the agenda, but we cannot confirm a date at this stage.
To this end, this has been noted on our website, and they will shortly be removed from the Asset Store – to be replaced by a brand new tool at some point in the near future.
The existing tools will remain freely available on our website, but support will not be available for for Unity 4.

We apologise for any inconvenience caused. Thanks for your understanding and support!
If you have any questions at all, please do not hesitate to ask.
Please note that this only affects the two aforementioned free tools. UniSky is fully supported on both Unity 3 and 4, and a 1.3 release with new features is on the horizon.
