Hi all,
I've created a couple of custom line styles for road marking, to be rendered with Luxology and hopefully also exported to LumenRT.
The first problem is that the thickness of my dashed lines does not diminish as it progresses further from the camera. It seems to suddenly transition to a much thinner line at a random distance. Why is this?
I've also created a solid white line with the same thickness/ width settings as the dashed line, but it doesn't render with the correct thickness.
Here is a summary of the issues, as well as my Line Style settings.
Finally - is it still not possible to export these line styles to LumenRT? Here is an old post on the issue;

Thanks,

Hello Max,
Slightly off topic.I noticed that your road markings are somewhat elevated above the road ('we all float down here Georgie'). Wich is not bad, because you don't want those distorted intersection artifacts that appear when roadmarkings are on the same elevation as the road. But you can turn off the shadows for roadmarkings only, so that they look less floaty. In the material editor select the material for you roadmarkings, turn off the Cast Shadow checkbox... and the marking will now look more as if they're stuck to the road.

Thanks Ivo – a good tip, and something I generally do when the camera is close enough to see it.
Strangely, CONNECT doesn’t allow a material to be attached or assigned to lines or line styles. I had to create a dummy shape, assign material and then delete the object.
It seems LumenRT actually does pick up these line styles, but the “no shadow” attribute is ignored in the dynamic view. Rendered views and movies, fortunately, do ignore shadows, but only from a distance.
In MicroStation linestyles seem to be displayed in a way that is similar to text. Text is simplified when it is so far from the camera that it is tiny and unreadable. Similarly, when an element is far enough from the camera, the linestyle is simplified and may lose it's physical characteristics in the distance. If you stencil your pavement markings they won't be simplified as they recede into the distance.
Another benefit of stenciling is that you can check Apply Marking Material which is a material set to cast no shadows.
Thanks Ron - It seems Apply Marking Material is only available in the Stencil 3D reference tool. Does this presuppose that all my linework is sitting in a 2d reference file? It's not available in the Stencil Selected Elements tool (which handles geometry already in my 3D file).
I'm not sure why the Marking Material option isn't available in all modes of the Stencil tool. It really should be.
The Marking Material is easy to make though.

Not even based on color/level? That's odd.
