Render the current frame Problem! :(

Hello all , my name is Constantine from Greece.
I am kinda new to Maya...but i can manage some things.

I have searched for hours for answer...but cannot get one...would be really nice if anyone could help.

I have 2 questions :
1)

So this is my screen ...

then i press the Render current frame button to see the result and i get this ...

user added image

why is the grass not appearing to my render result?
what do i have to do in order to see the correct result in my render?

and 2nd) question

when i save my project. and close maya i have done some things to the Hypershade ,
in this example i use my lambert2 material in order to colour the ground
but when i load the project up and open Hypershade , the work area is empty.
How can i open the lambert2 again cause maybe i want to change something in there.
(yes i have tryied to zoom out in the work area in case the icons are more to the left or right)


Here is an image so you can understand what i am saying :

Hi Constantine. Are you using painFX for the grass? If so, paintFX does not work with mental ray. You need to convert it to polygons first. (Under the Modify -> Convert menu option)
For the second, just right click on the material node and select "Graph Network"

no i dont use paintFX. I just used two images a Dirt image and a Grass image and then used them in Hypershade in order to be able to use the Paint Vertex Color Tool so i could erase the dirt and the grass would show up. Thanks to your tip about the Hypershade i can show you what i mean with this screenshot.

To which attributes of the material did you connect the dirt and grass file nodes?

tbh i didnt understand your question very well! but i will explain what i did.

i created a layered texture in hypershade.
added the dirt (pressing the 2D textures / File and choosing the image)
then with right click in empty space created a green small icon where i applied the grass.
and then middle mouse button to connect it to the lambert

then i created 2 UV Sets (Dirt and Grass) did the nessesary changes in UV texture editor, linked them (grass to the lambert grass and drit to the lambert dirt) and voila i could use the Paint Vertex Color Tool in order to while i was erasing dirt , grass would show up .

i really hope this answers your question! user added image

Can you show us the attributes of your layered texture? Also, what file format are you using for the grass?

You're not done setting up your shader yet. By looking at the layered texture attributes, you have the dirt texture blend mode set to "over" but you have no masking texture (the patchy texture you painted) plugged into the "Alpha" channel. This is what controls the transparency of the associated layer, and right now it's in a 100% uniform opaque state.

To your second question. Maya does not save the state of the Hypershade work area whenever you close the window, as Pixal said, you'll have to graph the connections or drag the nodes in.
