Skatter causing white background on imported models

[Victory7s]

Hi there,

I'm a university student working on my final project and I've this year taught myself how to use V-Ray and Skatter.

I purchased the Lotfi Bernoussi Vertical Green Wall photo real models so that I could create a vertical garden (located here: https://gumroad.com/l/tOyB)

For simplicity, I used one of the preset vertical gardens and imported directly into my Sketchup model.

I then attempted to render the scene with V-Ray and for some reason the leaves within the vertical garden have a white background, almost making them look like paper.

I'm not sure if it's scatter or V-Ray causing the issue here.

Does anyone know what's causing this and if so, how I can fix it?

(I just did a quick, unfinished render to try and show what I'm talking about. Apologies for not completely rendering it out, but that would take longer than's needed).

I assume you followed this tutorial, if not please do so.

Does the plant models render correctly without using Scatter?

It looks like opacity maps for the plant material didn't apply. Make sure folder paths for the opacity map is correct in the Vray material editor.
Opacity map is a black & white image as shown below:

Hi Filibis,

Thanks for your reply.

If I open the preset vertical garden in Sketchup and render through V-Ray, it works perfectly and renders without the white backgrounds.

It's however when I import it into my University project model and attempt to render that the issue occurs.

Hi Again Filibis,

I re-read what you said about the opacity map and realise that this could be the issue.

How do I check the folder path for the opacity map? Is this done through V-Ray?

You can find opacity at Material settings. When you clicked this checker icon, you will see the path it uses.

If it renders correctly on empty scene, try also a simple skatter on that empty scene to determine whether your university project file is problematic or not.
