Re: [Yafray-devel] Removing flicking shadows noise of Yafray Animations (Simple way)

[Laurence Mehlhorn]

 I use Yafray, and find it to be far ahead, I would like to see these changes added and a sellable yafray on the market place.

complete with Partical Rendering and Game engine capabilities, Improved Radiosity Processing.

 

Should not take a team long to make some of those changes.
