Would be nice to get this feature from the Max version :
the scale would be an integral part of the material and not carried over to the Texture Tag : great to build a one-click material library, quick and easy to use ( not having to guess the scale when applying the material )
it would make easier to mix different textures with various scale in the same material, like overlay / dirt textures
it is not the same as the Triplanar shader as it would work with any projection and helps avoid to use one triplanar shader for each bitmap shader ( and so halves the number of nodes in the material )
I've set this to pending, but it may get declined since C4D doesn't have Real World Scale in the same sense, and because C4D handles UV mapping VERY differently from 3ds Max.
