Hope you will find this of interest.I got rid of the Sklight and Indirect output ticks.It makes the system slow to work and rarely do I find any extra quality gained is worth the processing wait. I added a bulb light at 50 percent and placed/directed it at the lower part of the mushroom.For the basic mushroom I just applied the texture "celular" from the Basic proceedurals shader browser file.For the mushroom underside I used Sunset1 and for the ground Mossand Dirt both of which I extracted into a Terrains Shaders folder in the browser. Whenever I open anything in Carrara I allways extract any good shaders into the browser.
