Dirty streaks material new Vray feature in SketchUp

[waldob]

Hi team - can you please explain to me how this works. I briefly seen this in a webinar but I can't remember how to apply this.

Thank you.

Hi waldob

Generally, the streaks parameter of the Dirt procedural texture helps in adding a weathered look in occluded areas (including open corners - Inner Occlusions).

When using Ambient Occlusion, the Streaks Ambient parameter can be enabled and further adjusted from the Bias rollout. Examples can be seen on the documentation page (LINK)

I would like to post a few links where the streaks workflow is shown and discussed, hopefully it would clear things up:

Let me know if I can be of any further assistance!
