This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i
Although there might be a way to do this, I myself am not aware of a way. Usually when I want to select vertices or CV's, I'll select them, then hit 4 to go into wireframe mode, then hold down Ctrl and drag around the vertices or CV's I don't want to select.
Shift will select stuff, Ctrl will deselect stuff. I think it is very important to get used ot using these two things.
