shader mixer materials don't work in iray ?

I'm applying the shader mixer materials in the shader presets, but they all render as white in iray. All other iray materials work fine. Do I have to activate some special options other than applying the shader mixer materials ? Are the shader mixer materials supposed to work with iray at all ?

As I recall it the shader mixer materials worked fine in old iray versions.

update.

I see the shader mixer materials work in 3delight and they don't convert to iray. I was confused with the nvidia mdl examples which of course work fine in iray.

MDL is the shading language used by Iray, while 3DL uses RSL.

Each brick has MDL, RSL, or both as an indicator of which language supports it. The auto-conversion of 3Delight to Iray materials is hand-coded for the base shaders, it can't cope with an arbitrary Shader Mixer shader (or other custom shader).
