T3D 1.1 Beta3 - Interiors(.dif) have no shaders?

I'm having problems using .dif interiors in T3D, so far it seems as if .dif interiors are no longer applying shaders onto there respective textures and there is little to no information about Interiors usage in the T3D documentation...(plus the GG search is barely functional atm)

The warehouse on the left is Interior.dif while the warehouse on the right is tsShape.dts... same folder, same textures but interiors dont get the shaders, This is a problem as .dts files do not have baked-shadows using BasicLighting and the interiors already have a working collision mesh that would use less resources then .dts visible mesh and I would have to create a collision mesh for the .dts files(also GuiShapeName can see objects through .dts as opposed to .dif... but I'm not a big fan of the GuiShapeName anyway)
