Pink everything in Blender, even with all solutions i tried (searched Web for hours) I worked on a character in blender 2.8 and wanted to add eyes, just like Danny Mac 3D showed in his tutorial.

(sadly there isnt an eye tutorial for blender 2.8, and i want them to look good)

But when i add a material, and set the material output to cycles render, it gets pink. But i tried with an Uv Map and with unwrapping, but the pinkish color was still there. I did click on assign, but that didnt helped either.

Also finding (or reporting) missing files didnt work, since the blender console dont show where the files are. It doesnt react when i click on the 2 options.

I know blender 2.8 is beta ... but i wanted ... to try it out XD
(But maybe i just miss something and its my fault) 

Here are some pictures of the eyeball and the settings:

When i remove the material, the eyeball is white in LookDev, when the material is there, the eyeball is pink in render and look dev. Also the whole scene is pink xO







im thankful for any advice ... im really desperate since i try to fix this problem now since 1 day, and i couldnt find a solution xO
The issue comes from your shader:



Basically, you're trying to mix a transparent shader with "nothing". It's kind of trying to multiply by zero: it doesn't work well. If you set the material output to be Cycles specific while in LookDev display, it renders pink. If you go to rendered display, it will be black no matter the render engine.

So, try to add a shader into the second input of the mix shader. Or remove the mix shader completely.

If you intended to control the amount of transparency, just play with the color value:
