I think this is a very simple question for you.
I’m quite new to ue4.
I want to use custom expression nodes, I’m just playing with them and I see that I cannot generate a color from a custom expression node,
for example if inside the custom expression I do something like this:
float3 mycolor = (1.0,0.0,0.0); return mycolor;
and then I connect the output of the custom expression block to base color of a material I would expect a red color. Instead I have a black color…
Why? What I’m missing! I think that code is the simplest I can try.
