Grey haze around face me component (transparent PNG)

V-Ray V-Ray for SketchUp General
1

Hi all,

I’m trying to make a face-me component in SketchUp which will render in VRay.

Below are two screenshots of the plant in Photoshop, with a dark grey background. As you can see there’s no visible grey haze - I was very careful to clean it up as neatly as I could.

Below that is a screenshot of the VFB (and SU) which clearly shows a grey haze around the plants. This is really noticeable over distance, which is an issue as they’re supposed to be filling in a big area of meadow (along with other 2D face-me comps).

Below that are the material settings within VRAY.

I’d be very grateful for any advice you may have please - I’ve done lots of these in SU before but this is my first time trying one that will be rendered, plus I’m very much a beginner in VRay.

Thanks very much for your help.

Fi
