3ds max procedural maps: display issue

[till_botterweck]

Hello,
i had some issues with displaying max's procedural maps (3D maps like "marble" "noise" etc.) in viewport.
I used vrayMTL to apply one of these maps to my object and no matter what mapping type i used, i never got a coherent transition between elements and it really confused me to where i thought something is wrong with my 3ds Max install.

But turns out, if i apply the same texture/map to a standart material (legacy scanline mtl) everything displays fine in max viewport.
Also, they maps render correctly in vray BUT they dont work at all in the viewport (i got for example the same image on all 6 sides of a cube while in "Object XYZ" mapping mode).

Im aware that there are limitations with the display of certain maps but i wanted to ask if this behaviour is known here?
And also, what is the best way to work with max procedural maps and vrayMTL in the viewport?

For now, i guess i will have to always assign a Scanline MTL if i want to setup a procedural map, and then switch it back to a vrayMTL at render times?

Is there a way to asasign different materials to an object for viewport and rendering respectively?

thanks in advance

The mentioned procedural textures should preview just fine with a VRayMtl if "Show shaded materials in viewport" (SME toolbar option) is active. Maybe it's something more specific. Share some screenshots/scene so we can take a look. Otherwise, the 3ds max native Shell Material is used for previewing/rendering separate shaders.
