Hi guys!
Unfortunately I've noticed that the European Ivy in the Ivy library uses an incorrect map for the Translucency effect.
Look at my screenshot: The top map with the white background is completely a different type of leaves from the bottom one which is the diffuse one and is used in other slots as well. In the viewport you can see the mapping of the translucency map on the leaves, completely wrong and the rendering effect is quite weird at the end...
I didn't check the other Ivy types in the library but here yes, we have an issue.
Thanks,
