How to make a checkerboard pattern by LUA in FNF?

Question

I was wondering on how to make a checkerboard effect or pattern on Psych Engine (Version 1.0.4) Without any source code, is there any Lua scripts that can help me do that?

You can't. Lua and Hscript only runs in songs in base Psych Engine, and can't affect anything outside of them besides things like options.
