Rendering-transparency map stays black

Custom material transparency was dead for the moment (current Rhino version). See here:

RH8 - Raytraced mode alpha issue

Hi, i have an issue with “Custom” and “Picture” materials. This types of material dosn’t show alpha (trasparency) in Raytraced display mode (in Rhino redner too). No matter if i have PNG with alpha or if i use transparency map. In Rendered mode looks tramsparency OK For BPR materials is everiting OK in both display modes… Is there some bug, or is problem between desk and chair?

Rhino 8.15 apparently has this issue fixed.
