I can do it.
But can it be any figure?
Can it be my robot mecha?

any figure. but without lights.

You're talking about using a square with 100% white in the Ambient channel, rendering with Global Illumination on.  Do not confuse this with an area light as used in other rendering apps, this is just Global Illumination doing what it's supposed to do.  The term "area light" has a specific meaning in other apps that is not related to GI.

Also note, you pretty much have to have some kind of polygonal environment (a ground plane, at least) for GI to do very much of anything.

edit: manoloz got your point obviously, although note it would behave differently with a ground plane

i understand this. i just want to see if i can get with GI at least some lighting  from props with 100% control.
