[PD] Image from shader back to Gem

[Jack]

Snap a render scene as a texture, [gemframebuffer] is the way to go (for
me).
You render your scene as usual, just replace the [gemhead] with :

[gemhead]
|
[gemframebuffer]
|
[translateXYZ 0 0 -4]
|
...

hop, you can grap the scene below [translateXYZ 0 0 -4] as a texture
with the right outlet of [gemframebuffer].
