Rendering object only to a texture (not visible in game)...

[USAGuerrilla]

In unity recommended way to render objects only to a texture is to use layers. KSP already uses all the layers.

Any other good ways to achieve this without moving those objects got knows where (so they aren't visible in the game camera)? Thank you!

The layers may all be in use, but probably not all of the time. 

Maybe try to find a layer for VAB part icons, or something like that.
