Im a complete newby when it comes to mental ray.  I want to be able to use UV map psd network but I cant seem to get any attributes to show in the options box.
does anyone know of an idiot proof tutorial on MR shaders?

Not real sure what your asking, you want to use a PSDnode in your shader or you want to UVMap your model?

Ive never used mental ray before. The first thing I discovered was that it didnt seem to like psd maps that were simple hypershade items, but jpgs were fine. I then tried to create a UV map using image/create psd network in the UV texture editor. when the option box opened it had no attributes, like color bump difuse etc.
I realise now that I need to find some tuition on the subject but am not having much luck finding anything on line
I hope this is clearer im not the best comunicator sorry.

When using PSD’s, be sure your plugging them into a ‘PSD file’ node and not directly into the material (then plug that PSD file node into the material).

MentalRay doesn’t support all of Photoshop’s fancy FX, but for the most part, you should be able to use your PSD file(s) just fine.

To access your material’s attributes, double-click your material in the hypershade or hit ctrl-a.
