Trick.

Hey painters!
A few times people were asking me how did I done «reflections» Like this:

or this:

As may you know X-plane does not support any reflections or materials for obj`s so there are a one trick for you. Its a static cheat but I think better than nothing.
For example I grabbed Homer.Simpson `s Great AAL livery.
And pasted upward layer from PK caled «paint» (fusel2 its called «Pnt» Sorry...:) ) with multiply blending and 90% opacity.

and desaturated this layer

result is:

You can control «reflections» by setting opacity or diff types of overlay, or maybe copy paste layer one more time.
Some one like this some one not...
but may be someone find this useful
