Hey!
I am sorry guys for being a bit quite here. But its time to get that stuff
sorted. There are so many tools written or half written but nothing is
moving ahead. I will sort some code leagal issues out asap and I want to
start an open source project. Its time to get this sorted once and for all
:) Mattes, volume noise, some more holdout and fog nodes, all the stuff we
had, and make the tools even more handy. Once we have something established
and build some force behind it we can maybe get the foundry to spend even
more time that they already have on the API and take it from there. Its
time to get going with this! Just let me move to the USA this weekend but I
want this open source project X happening by the end of this year.
