This raytracing feature has nothing to do with yafray, it is totally separate from it. It would be nice though if the parameters would match those of yafray a bit more. Fresnel is not quite what it should be (it should depend on ior), and the ior range itself is also a bit unconvontional, but I understand this is a work in progress, so things could probably change in later releases.
As far as yafray integration is concerned, this is still being worked on, but will happen sooner or later.
Anyway, nice work Ton, thanks for all your hard work!

Hail to the Blendergods,

We request and They deliver beyond our expectations.

With such capable and inventive people (Coders, plugin writers, MakeHuman, Beast/Building Project) and great community on Elysiun (allways ready to answer questions or compile the newest stuff from de CVS (yep, you ztony) Blender seems to have lift off to greatness

By Jove I want to thank you all and wish you the best darn christmas you ever had.!!!


greets

Ton your the man. Sounds good. By the way...this is why I was asking about shadows casted by the opaque areas of an alpha:

I cannot believe how quick this progress is being made on this. Does Ton work full time on Blender or is this sleep deprived part time hacking?

Just committed another feature, transparent shadows!
But let's be clear, no caustics here, for that you better need photons and use a real tracer like Yafray!

http://www.blender.org/bf/rt2.jpg

Also improved is the 'fresnel' effect, to make edges of glass look less
transparant and more mirroring. This thanks to the formula eeshlo
emailed me. Thanks a bunch!

Blender file can be loaded here:
http://download.blender.org/demo/test/
Also a new OSX version is posted there.

(added note: yes, i like to be as compatible as possible with yafray as
well. IOR and fresnel now work identical. Although I still allow some
extra artistic freedom :-)

Ton you're the man!
I cannot express how much this means to me...

Thanks and a Merry Christmas to you!

Ton , was the .jpg made with Blender traces or Yafray ? I tested your blend file and it does not render that

Nope I don't get those either.... But the refractions give me the same result as in Ton's render.

Man am I excited!

I didn't realise it either, but the transparent shadows button must be pressed on the object receiving the shadows. This button need a better label..

Ton -

Thank you so very much! To say that these are great additions would be an understatement.

Question: Now that reflections, refraction, and transparent shadows have been implemented, does this mean I can render a glass accurately without the NOR trick?
