Map Scaler Binding

[Theo]

Well, it's my problem:

 

I always use the file link mananger for my adt files, and I worked like this:

 

1 file for a floor.dwg

1 file for the base of the building (base.dwg)

 

and in 1 file I put both by xref (dwg), in viz It cames like a viz block, I do this to in a need of change the building I just change one file (floor) and all the building are update.

 

But is in the material that I gat my problem I always apply material multi-sub object in the vizblockx (xref) where each ID matches with color of my original file, separating the uvw and the material for each kind of surface.

 

I recently get the vray, but the uvw don't change the appearence of the map, it isn't came correctly, because of "Map scaler Binding" the bitmap looks like a "fit" on my walls

 

Is there a way to make my vray works fine with uvw? or how I can link a dwg file without the "Map Scaler Binding"?

 

Anyway, thanks
