Vray Bitmap converter does not convert into Bitmaps with Mapping Source connection

[caypiranha]

standard bitmaps, converted, nodes are now showing that it is a VRayBitmap, but it does not inherit mapping sources, and the node in Slate is also only called "bitmap" instrad of "VrayBitmap"
what may happened here? (Vray 5)

If you refer to the RMC menu, it works just fine for me, and it only appends "_VRay" to the map names (attached, "Map #1" converted to vraybitmap).

I don't understand what you mean by "mapping sources", particularly for max bitmap loaders: could you elaborate?
