I wanted to learn something about shaders, so I watched some tutorials. However I immediately get an error if I try to use a Custom Function.
The Custom function is telling me, that I need at least one Output-Variable. But as soon as I create one, I start
getting errors. Please have a look at this screenshot:
Just try to add valid shader code to the source slot and see if the problem persists. Try some of the examples in the manual? It should work ok, and the errors usually go away when you got the code syntax correct and all the inputs and outputs assigned, and in correct order.
