Yep, it would be especially useful for when I line up cars for screenshots and accidentally press just a little too hard on the throttle...
Together with a slider for amount of tiremarks. They are quite resource-intensive so it's recommended to leave them at the default values that each Overall Quality profile sets!
I’m glad the op brought this up because I was thinking the same thing too a number of months ago. And while we’re on the subject— the ability to darken the tire marks if I want them like that would be kind of nice as well. Or is that what the slider up to 2000 in someone’s photograph taken earlier is for ?
