SketchUp to Artlantis, texture export problem

I made a plan in SketchUp (latest version), including models imported from 3D Warehouse.
I exported it as an .atl file, but when I open it in Artlantis I have problems with the transparency of some of the objects imported from the Warehouse sketchup: in particular the tree leaves that appear with white outlines.
Could you give me some advise on how to correct the error?

Thanks in advance,
Vincent M

Bonjour ,

The white outline might be coming from the material under the leaf texture, you can drag & drop the « invisible » shader on the leaves and let me know if you still have the white outline.

You can send me your SKP file, I can check it and let you know what the problem is.
Use WeTransfer and post the link here, or send it directly to me

Best regards,
