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 ...



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 :





Thank you in advance
With Respect.
