I’ve been working with a scene with lots of picture frames with transparency (png). Somehow this morning all my picture frames disappeared …
They are there but they are now completely transparent so I cannot see them unless I switch to wireframe mode and all I can see is the outline of the frame.
Somehow the alpha channels are not functioning properly. If I go to the material and I turn off the transparency the image appears but turning on transparency makes the whole image transparent, not only the masked areas.
However, the scene renders correctly, so it seems to be only a viewport problem.
I rebooted and repaired Rhino 64bit installation to no avail.
However, I loaded the 32 bit version of Rhino and loaded the same scene and the problem doesn’t occur and the transparency works fine and the picture frames display correctly masked.
EDIT: See attached. This is what I have to do after creating a picture frame in order to show up. Again, it doesn’t happen with the 32bit version and it never happened before in my regular 64bit version.
However, although the image shows up in the viewport with transparency, it looses the transparency when I render …
