Yafray Methods

[DracoFodder]

I’ve looked through a few tutorials on using yafray, I finally figured out what I was doing wrong in my rendering. I’ve even gotten one item to come out looking reasonably like glass. (after beating my head against the desk for a while, that is)

I think my main question now is in how to step through the process of getting a good render out of yafray.

Example, I want to draw a wooden box, holding a glass cube, light coming in from the upper right of the frame. I can get the basic shapes in place, the materials, color, set my lighting, and render in Blender internal. Things look acceptable for a test. Flip settings to yafray and render, 10 minutes later I see that all the colors are not even close to what I want. (Well, exaggeration a bit, but in larger size/quality it does take a significant amount of time)

So, is there a rule-of-thumb guide out here somewhere for an eager newbie? Or is it magic, which I shall learn in time young grasshopper?

confusious say:

if you don’t need Yafray, don’t worry about it.

there are probably incorrect settings in your materials, or you might have some export problems, but for the main part, if you can do it with blender internal, that is the way to go.

Ahh, but isnt yafray the ideal way to get realistic looking clear materials? Or am I misunderstanding all the discussions about that. Esp when people are talking about phot-realistic renderings.

Not that I’m near that level of modelling quality, but I’d like to be at some point.

Yafray’s glass and refractions are made using the Ray or Z-buffer transparencies, as well as Alpha, so try that. And also be sure to use a photon light to simulate caustics (which is the light rays going through the glass and lighting the table in all of those peculiar ways, in case you didn;t already know…)
