I used to use 2012 and for a long time and then went to 2015 where you can't change the output gamma. My first workaround for this was to enter fileOutGamma=1.0 in the script windows. For some totally weird reason this just stopped working. So I've been saving out as EXR and that's been sufficient. But just now I tried that and still, the results are different (between VFB and output file) and it's because I never really grasped the ins and outs of this whole gamma thing. Should I have the sRGB button on or off? I don't know. Is anyone able to give me a run down of how I should be working? I basically just want what I see in the VFB to match what I save out. Thanks

Hi everyone, New to vRay, could someone confirm whether or not I am setting up linear workflow correctly in maya? Here are my settings: Image Format: EXR vRay Settings Color Mapping (I believe checking the 'Linear Workflow' box is not the way to go) Gamma Correct Node Insert .454 gamma correct to 'Diffuse Color' and diffuse textures (but not for bump/spec/greys) Click sRGB in vray VFB Could someone please confirm whether I have got this correct. Many thanks

Hi, Now I am really confused. First of all... I know how to set up the lwf and a decent knowledge about it. But.. I was trying to find out some lighting tutorials for the interiors with completely artificial lights... but didn't found any with LWF. Now I've some doubts, may be you people could help.. (and I think this time I really needs the Expert's help:confused:) (LWF settings: max gamma:2.2, input and output:1, (with the texture input override with gamma 2.2) affect color and material: yes, color mapping: linear with gamma:2.2 and "don't affect colors" option ticked.) 1. Is the color mapping options works with lwf?? I don't find any difference by using different options...! 2. many people says that "don't affect color" should be on for more details. is it true? what exactly it do? 3. Why don't I found any good tutorial on it? every other tut is based on LWF basically on a day time. 4. Even the evermotion site tut (http://www.evermotion.org/tutorials/show/7900/making-interior-scene) is not using the LWF. another: http://www.3dtotal.com/forums_frameset/index.php?e=http://www.3dtotal.com/tutorial/3d_studio_max/bedroom_white_and_wood_scene/bedroom_white_and_wood_01.php If it is a so good option then why not they are using it for their scenes? and yes ... I do not see much color bleeding in their images. How did they manage it? with override mat??? I doubt it. 5. Is there is any need for AO pass in interiors? if yes how can we achieve it without having any environment? 6. Again ... is it really good option to use it in the given case...... or should I switch over to normal reinhard etc for the interiors??? There are a lots of question are running in my mind. But please help as I starts using the LWF but could get the decent result with it in interiors with artificial lights.

I was just wondering if anybody still uses gamma 1.0 or if everybody has decided that gamma 2.2 is better. I, personally, use gamma 1.0 exclusively. I have tried the gamma 2.2 workflow in the past but it proved complicated to set up and the results seemed to be somewhat washed out (no I didn't apply a gamma correction twice). I want to know if I should feel stupid for not using gamma 2.2 or if anybody else is like me and is sticking to 1.0. Also a side note: changing gamma to 2.2 would, in theory, ruin all the materials you get off of a site like http://www.vray-materials.de, correct? If you change the material editor settings to be gamma corrected as well, wouldn't this mess up the reflection amount seeing as how reflection value is tied to a color value that has now shifted? So, 1.0 or 2.2?
