Open the TGD below .
Make a quick render.
You will get something like the picture "planet_sun_test_01"
Then go to the "Planet 02" object and open its internal node
part.You will see 4 nodes. One node -the Atmosphere 02- is in OFF position.
Take the "Cloud layer v2 01" node over this OFF Atmosphere and make it go directly to the Atmosphere shader input (bypass the OFF Atmosphere node).
Now make a quick render ones more. It should look like the second image here(planet_sun_test_02).
Now say you don't like this and want the same render as before.
Put the Atmosphere 02 in the same position as before (between Cloud Layer v2 01 and Atmosphere shader input).
Don't change its state (leave it OFF as it is)
Now make a quick render again.
What? "planet_sun_test_03"...
It should look like the first render (because everything is the same as you open the TGD), but it looks like the second render?
Is this a bug? We should make the same render with the same node states. If this behavior is in other places too it would make TG2 much more hard to use.
Can you guys test this too please. In case i make something stupid here ?
