Transparent pictures appear solid when exporting to PDF


I have an object which I would like to texture in the layout space.
I have a Picture of a Concrete texture which I have Imported into my layout space. I have overlaid it across my object I’d like to texture and pulled a Meshoutline from my model space into my layout space. I have then trimmed the Picture to only cover the extents of the object behind. I have then lowered the tranparency percentage in the Materials menu of the Picture to see the Object in the viewport behind.

It looks exactly how I want it in preview, but then when I export to Printer or Print PDF, the transparent image becomes solid again.

I feel like this should work the same way a Transparent Hatch does but it does not.

I am using Rhino 7 on a Mac, Big Sur.
See Images below for reference

Hello - so far this works as expected here, as far as I can see - can you export that bit you show in the images and post that here?

Please also run the SystemInfo command in Rhino and copy/paste the results here.


Hi, what do you mean ‘works as expected?’ Meaning; it works fine on your end? or rhino doesn’t have the capabilities of printing transparent Pictures…?

I’ve attached the file which includes the test layout page. See Below.

Hello - thanks - I see that printing from layouts does not behave correctly on mac. I will add a bug track item.



Thank you. That would be appreciated!
