(I'm sure this has been mentioned before, but I couldn't find it.)
I'm trying to produce some 'technical' style documents for some furniture where geometry is transparent and you can see connection details and objects behind/trough the main volume of the pieces. But as soon as Enscape recognises the texture as transparent it looses all the outlines. It would be nice to have a check-box for this against the specific material (could be annoying for glass).
(Current solution is to 'hide' the pieces, generate multiple renders and merge all the images as layers in post.)
