shop_disable_shader rendering parameters

[davpe]

Hi, 

I'm wondering if anybody knows how rendering parameters in Mantra > Shaders > shop_disable_* are supposed work? It's pretty handy feature for globally disabling/enabling different parts of shaders but it seems to act quite odd. For instance if you want to use `shop_disable_displace_shader` it does work as expected if assigned to an object. if assigned to a ROP though, it doesn't seem to do anything. on the other hand, `shop_disable_surface_shader` seems to work for both object and ROP. `shop_disable_shadow_shader`didn't seem to do anything last time I tried to use it, although I am pretty use I successfully used it in the past. so I'm completely confused. docs says nothing. are these some obsolete parameters that don't work well with pbr or did I just misunderstood the purpose?

thanks for useful replies.

D.
