bmx code:

Type TTest
	Field path$ = "1.txt"
End Type

Local class:TLuaClass = TLuaClass.Create(LoadText("1.txt"))

Local obj:TTest = New TTest

Local lua:TLuaObject = TLuaObject.Create(class, obj)

lua.Invoke("Pick", Null)

Print obj.path

Lua code '1.txt':

function Pick()
        print(path);
	path = 'ok';
	print(path);
end

console:

1.txt <-- Lua print()
ok <-- Lua print()
1.txt <-- BlitzMax print() after lua call

Why Lua creates a local variable?

It creates a local as you tell lua to do so.

If you used a different variable name for "fiels path" it would be more obvious.

To access the obj's field "path" you need to access it via the exposed name of the obj.

Edit: I suggest to read this:
https://en.wikibooks.org/wiki/BlitzMax/Modules/System/Lua_scripting

It will explain what is missing too (hint: registering the obj to lua)
