You can work now with a background image inside the plugin. LW compositing features works with Octane, you only need to enable the alpha channel in the kernel options.

Ah, did not know that.

It seems there is a problem in Direct Lighting resulting in black ceiling, even with short AO values and new sky model. Anyone else?

Can you share a image or a scene that show this issue? ... what are your kernel settings?, perhaps you should use de diffuse model inside de Direct Lighting kernel, not the AO one.

Diffuse mode does work, but there is no reason why Ao would be corect on the walls and not on the ceiling. Look on pic 1 and 2 , whatever the AO value is, there is no change in the blackness of the ceiling. Plus AO mode is WAY faster for animation.

Sorry you are getting hammered with folks having problems Juanjo... but add me
to the list...

Is there any way in ORLW to have a Diffuse material with Matte enabled, and have
it not apply alpha to its shadow areas? (so that it can act as mask?)

I have an object in my scene that I want to mask stuff out with. It is front of some
things and behind others... it is masking stuff - except for where it has shadows...
alpha is completely black for this object - where it does not have shadows.

I have Alpha Shadows turned off in Render Target.

Can you post the picture and the alpha pic with this issue? ... I will try to make some tests tonight to see how matte works.

Can you send to me the scene to make some tests? ... I only need the basic room geometry model, without forniture, textures, etc., but with your lighting setup.
You can send it to me to [email protected]

Anyway I will make some tests tonight to see what could be the problem using a basic box room.

Ok, nice! Thank you, really, I think everyone here is appreciating your work. The integration is AMAZING.

Juanjo, I am just going to use MatID for now.. really not that tough for stills...

However, the Matte functionaility in Diffuse (whether its intention is strictly for
ShadowCaster or not) is damn close to being able to used for masking. It is likely
just a matter of duplicating this code and stripping the shadow stuff - to make
a Mask feature... which would be very, very nice to have. Maybe you could
mention this to your contact(s) at Otoy - since we are all trying to make Octane
more useful/powerful for compositing.

Thnx again bro
