The image i attached basically explain everything i confuse with.
The absorption node group i downloaded from the internet.
AND IT CONFUSING ME!!!
I made a comparison between all similar shader,
AND I CANT TELL THE DIFFERENCE!
Sorry, i am a bit stupid, i really cant get the idea from it.
can anyone please explain this to me,PLS:(?
2, 3, 4 i added a absorption node on it, and i dun know what those really do,
it was told to be making glass realistic,
but it seem to me just make thing darker, and even more ironic is
when i put 5 next to them ( 5 is just glass shader, nth more) it look pretty well enough,
no need add more node to it.
Q.1 May any1 tell me what this node does and what it applied for? ( i mean people said is applied for glass and make
it become more realistic, but i really want to know what theory they base on support this statement? )
6 and 7 i put volumu shader on it, and also.
i really dun know what it really does,
it just seem to me make all things darker.
Q.2 May Any1 tell me, what volume scatter and volume absorption does? I want to know the theory behind it,
Just like Why it make thing darker, and what it can applied for real life object.
Q.3 Is it the node group i downloaded from just overlap with the function of volume absorption? these two basically
do the same thing if i didnt guess wrong?
Sorry for so much question to ask, but i kind of stuck in here, i did research on wiki, and watch various video
but i just dun get it, it just make me more confuse,
Pls, help me out on this, so i can move on to my learning progress:(
thanks a lot.
i appreciate it.
