Hi,It is a known bug of MakeMDL that you can not have only one object that you attach an effect to (in that case it is also easier to place the effect with a piece of XML code). You need to have at least one visual object as well.If you effect does not show, it could be that you have an exclude active in that area. That is another known bug of attaching effects, they are excluded by active excludes. To solve this you need to remove the exclude or place the effect with some XML code.

Let's hope they do for the next version of FS :).The Fs2004 version of MakeMDL had quite some bugs of the Fs2002 version fixed, unfortunately there were some new ones as well.
