Hi!
I'm building now my custom shader and please help me with one issue - I've attached my hip file and I don't understeand why when I add empty “properties” node in /shop/wd_shader it shows errors.

Without this “properties” node everything works ok, but I want now to add some properties to this shader.

What I'm making wrong?

EDIT:
please tell me too why my names of parameters in my material are default so long, for exeample, when I move my mouse over “Base Color” I can see:
“vopsurface1_baseColorr vopsurface1_baseColorg vopsurface1_baseColorb vopsurface1_baseColora”
and not
“baseColorr baseColorg baseColorb baseColora”
?
