mr vs scan line rendering Difference

[mskin]

Im trying to do a simple fly through of a site model in progress for my boss. For some reason the parking lines don't show up well in the Mental Ray render but do in the scan line render (both attached). I assume its an antialiacing issue, but i tried using the material override in the material editer for the parking lines and it didn't seam to effect the outcome. i am proceding with this "test animatiion" for my boss, but the final project (that may include an animation) i will want to render with mental ray. does anyone know why im getting these different results? -

 

the images could have been bigger, but they get the point across - barely...

 

thanks

What AA settings are you using? 1/4 4 is standard but for realy fine stuff go up to 1/4 16, what the rendertimes though.

 

The material override is for Radiosity not MR. You could tru supersampling them as well.

 

How are the lines made?

Thanks justing, the 16 setting made the difference. the lines are modeled, 1/8" strips ontop of the blacktop.

 

thanks again.

To help make the "pop" a bit more make them non-shadow casting and give them a little thickness.
