Legend help!

[dcscraig]

Love this! Im trying to get legends to work. I think I have the placed correctly and the preview shows promise and similar to what I have seen in the youtube videos, but when I render the legend is not subtracted. I'm I completely misunderstanding something?

RENDER = ["legends","keycap"]

preview

render

[666dsa666]

%legends as it needs to be transparent.

RENDER = ["keycap", "%legends", "stem"]; //
