why don't you use the black diffuse and white environment trick for alpha pass ?
already did think about it .. i did also think about a way of doing my mask , as i can now record my camera position trough the maya conection
but still this is not an ideal solution .
would be nice to have a switch on each material ...
i understand the limitation of gpu calculation and the memory issue .. and i do not even think or wishe to render everything in one pass . (as a mask pass by itself would be very quick anyway )
It look pretty darn cool to me
thank you
Where is your frustration from?
well ...
do not get me wrong guys .. i really like octane and do not mind supporting or advertising it .
as a matter of fact i wan to believe that having my mini iron man on the front page of cgtalk /spinquad and cgchannel might have help to sell on or two licence
i also understand that octane is still in beta .. and do not have all the intended feature yet ( an i hope that more cool stuff is still in the oven )
please take what i write next for what it is worth .... also .... almost nothing
my frustration at this point is coming from the fact that .. ( stuff that i consider very basic )
- no self illumination material (or light object )
- not being able to hide some object when i am working on an other ( example hiding kanneda from his bike )
- not being able to save or import material
- feel very limited with lighting as i do not have access to ""real"" light or a object with a strong luminosity
- no volumetric light , although i am looking into how to composite some mental ray stuff .. now that i have the connection from the camera to maya
granted that the main part of my frustration might come from the fact that i friend gave me a demonstration of his workflow in Arion and somewhat it was impressive ( yes i know it cost 10 x more

)
especially the part about material gestion
and teh fact that he could switch easyly between different render mode
object id / surface id and so
that he could color correct and modify his texture at loading time
as much as i was impressed i still prefer the interface from octane and especialy the price
( beside the fact that we have direct access to the devs who seem to genuinly be interested i what we re saying )
well that all for now
i am currently rendering my last test on this one .. and would give it another try with the next beta .
i saw that you location is La ?
i am down in santa monica ...
care to meet over a cofee and donut ? may be we could start a octane user group ?
