Vray dirt or Vray distance texture (Dirt, weathering, and ambient occlusion)

We need to have a future feature like Vray Dirt or Vray Distance Texture that allows us to add effects such as dirt, weathering, and ambient occlusion. I believe Vray Distance Texture tends to slow down realtime rendering, as the Vantage team informed me.

They achieved the effect with V-Ray Dirt. This effect allows us to add oil marks on roads.
