Issue with removing white background in vray

[wforwill]

I’m having an issue where this grass (from 3D warehouse) creates a white background when rendered in Vray. There is no background in Sketchup, only when i export. Thanks!

Edit Material in V-Ray and add Opacity > Diffuse Texture Alpha

In SketchUp, you could also hide perimeter edges.

Thank you but sadly no luck. I did the vray opacity changes with no luck.

Then, in the 2D graphics program of your choice (Photoshop, Affinity, GIMP, etc.), you can edit your texture and remove the white background, leaving it transparent or creating a black and white texture to use in V-Ray for opacity.

Or you can test the new extension from Fredo - Pic2Shape, and remove the background.
