arch & design mtl

[zeronove]

I've just noticed a strange behaviour about arch & design mtl:
it appears in my material editor as an available option only if active shade (VRay RT) is selected in the render setup dialog; with production selected (VRay SP3a) it's missing (see attachments); anyone can confirm this? maybe a little bug or I missed something'

just make sure that you renderer for you material editor is VRay and not RT or Scanline

Thanks for your suggestion but the material editor renderer is locked with the one selected; to double check it I've just unlocked it but that doesn't change anything, other ideas?
Can you access the arch & design mtl with VRay SP3a selected as production? I mean, can you see the yellow sphere (Arch & Design) as shown in my second picture but with the setup of the first one? or the only way is to activate the incompatible material checkbox?
