Max Nitrous Viewport Clay in Blender?
greentooth
One thing I miss about Max, having transitioned to Blender last year, is the viewport clay mode. I believe that had something to do with a nitrous driver that Max uses? Is this something that can be implemented in Blender? Or maybe a future feature? I like the matcaps in Blender, I just really like the old Max clay. 
Thanks

Is this what you want?
If yes I've been using Eevee to achieve something similar to great effect. The downside is that it's not a matcap, it's a material, and as far as I know Eevee still doesn't have an Override material toggle so that needs to be assigned manually.
Material setup:
You need to switch to Eevee for a second to turn Ambient Occlusion on for this to to work. You can switch to Cycles once you do it and use the material preview as you clay viewport then; that's my preferred sculpting setup in Blender.
Eevee's handling of the AO node is different than in Cycles. It's nothing but a mask output of the the scene's AO influence on the object, making it quite fast. You'll see that messing with the settings like I did won't affect it, but it does take the normal map input into account which I really like.
You'll still have to add and name the material before loading the node tree, but extending it to fully generate a same name material in one click shouldn't be too hard if you happen to know Blender's API and a little python.
..is not what you want.. (i forgot th mark the left-right-arrow under the cogwheel to change the light)..
Ever thought of just using a sphere with the max clay and render you own matcap ?? And installing using Blender -> Preferences -> Lights -> MatCaps -> Instal.. ) ??
