hiding components only saves memory as long as i haven`t made them visible since loading the scene. When i`ve made some parts visible the Ram-usage increases but it doesn`t decrease when making them invisible afterwards. At least that is what i`ve noticed.
The Ram usage is not so much of a problem until i try to export the scene as a whole, but splitting it up into different parts works.
But i`m not sure if my ram is enough for texturing. We`ll see.

@Michael

something i`ve never thought about before, but is MOI a 64bit application and able to use more than 4GB Ram ? I`m on Win 7 64 bit.

@ Rainer

I just wanted to show the whole object, it`s not the camera view. At the moment i`m doing a test-render. When it`s done i`ll post it here.
The details should be better visible then.
