Figures my first post here would be to ask for assistance.
After I build a network, I almost always go to UDI to test intersections, transitions, and etc. I've noticed when using RHW-4 and RHW-6 Inner and Outer Curve, the UDI breaks when the outer curve meets the diagonal, but not in every instance. Sometimes the UDI breaks on the inner curve in mid course.
The RHW-4 Dual Curve works fine.
Assuming the problem was in my assorted Plugin files, I moved everything out of my Plugin folder (uninstalling NAM32 first), and finally doing an uninstall and fresh install of SC4, and a fresh installation of NAM32. No other plugin files were installed. I used the Custom Installation of NAM32, and only enabled the MHW option.
I first noticed this when I was working on a city from an imported map. I also tried with a newly created region, with no terrain changes.
I've tried overlaying the curves on existing RHW, and plopping the curve and building towards the curve.
I've also searched this forum (and others), and haven't seen anything relating to this.
BTW, I have to admit that I haven't been a Simcity player in a while, but after stumbling on haljackey's and MandelSoft's YouTube videos, I've become totally addicted.
