And its a make-or-break one. Yeah, that’s why I wrote in the geekatplay forums, but people don’t seem too interested in the issue. And its a make-or-break one.

I was hoping I was wrong... but I guess I am not... damm it... it's really a pain... I really don't know why the heck they just don't simple apply a general output gamma correction node ? can't be as hard... now they have XStream 8 and still it's not working with a linear work flow.. grrrr........ maybe there is any work-aound... also.. I just have the PLE version, does someone know how to contact Eon and tell them ? When ever I go to there website, you need to be a registered member.. looks like I need to purchase the real XStream and if you just have PLE it doesn't count ? ohh please, if someone knows how to tell them please let me know... hello… well..

It's about time E-on wake up to the world :) Until then, I don't see any alternative to applying the inverse gamma at the end. This sucks. Yes, you are totally right.

on your latest render you show, the Output gamma 1.8 AND materials’ color gamma 1.8 ….. you can see, that you have gamma corrected the materials…. but you didn’t gamma correct the atmosphere.

that means, the whole scene was global illuminated with an environment which is still in a non linear gamma space.

but in order to make it right.. and please correct me if I am wrong… … you need to get sure that your atmosphere (in this case your environment) needs to be gamma corrected as well.

And this is a major problem. Because the atmosphere is basically the environment which is used to illuminate the whole scene.. technically speaking it's used for the GI. That means, you can gamma correct the texture maps you use for your materials, but the environment still lights the scene in a wrong gamma space. I also realized, that I can't change the gamma space for materials that are used for trees and plants at the ECO System. it looks like I am not alone.... read this interesting thread here: http://forums.cgsociety.org/showthread.php?f=162&t=842551 if you have any answer to that issue, please let us know. well… it’s right you can add a gamma node to the texture maps.. and yes you also can add a gamma node to the procedural colors….
