Error vector type...

Hi guys,

Oops, I am creating various advanced materials, I currently have a problem when I subsequently assembled a group node attributes.

Below is the error message, you know from where it comes from?

The problem come the Decals nodes group… But, whyyyyy ?? I’m ungry for this problem

I begin to centralize or comes the error, but I still do not understand .

I put several images textures parameters in " Settings" to the material body … and apparently it’s limited number of texture images that are converted into parameter ? Why ?

Sorry for this…, but, UP please. :o
