Can anyone explain what VFB Channels are for and the affect they have.

VFB Channels
They just add different output channels to the VFB. By default I believe we just have RGB and Alpha channels. Just for testing purposes add Z-Depth and Normals and then render a quick test image (a sphere will do). Then, in the VFB, click on the combobox in the top-left corner (where you should see “RGB Color”). Now there should be four different channel choices, RGB, Alpha, Z-Depth, and Normals. When you save an image from the VFB all of these channels will be saved out to separate images, except for RGB and Alpha, which should be saved in together if your saving in a file format that supports alpha.
The rest of the channels just show different aspects of the final lighting solution, GI additions, Caustics, Lights, Shadows, Diffuse color, etc.

Thank for the explanation Joe, Just wasn?t sure what it was for.

No problem, just as another note about them- the more channels you are rendering the longer the render times will become.

Thanks for that Joe,
Can I ask another question of you, what affects the detail or sharpness of the rendering, I want to show fine details, but I feel that I am missing something, some setting or sub setting in v-ray that will up the detail better than I am getting at the moment?

More details? … for me it helps to disable “filter maps” at the Vray options. It’s the same like disable the filter map at each texture interface. I feel, the default filter size of 1 is to high, but 0 works fine here.
So you get best details for textures.

Hi, Micha,
I will try what you are saying and see how I get on.
I changed from Irradiance Map to QMC as primary and light Cache as secondary as you suggested for my closet render, I did find that the detail was better, thanks.
I am trying to understand what settings to use for detail / sharpness.
Thanks again Micha for you help
Regards
