A little update:
Test or not i wasn't pleased with one scene and disregarded it and made a new scene.
The old one was even at a test level not good for my taste.
The new one is kind of complex and new for me so it takes a little longer then i anticipated.
This is the scene i trow away:
[attach=1]
This was the same but original one:
[attach=2]
The original needed more work too but i don't like the new wide format version.
The composition is bad and would need more work. The vertical composition in the old one looked better to me.
Even animated i didn't liked the newer version. So this one is out.
In the completely new scene i made, i had a very big object in the background with too much displacement
and the laptop where one part of that scene rendered crashed at a certain point even with 16 GB Ram.
I rendered then only the background with that object in lightwave and used a poor mans compositing approach
by using the rendered images in the background node in Terragen.
I am still not comfortable with using passes-render elements as it should be(A good tutorial would be nice). But hey it works
One third of this new scene is finished.
See you soon hopefully here ones again
