Yes, you got my rendertree correctly.
I guessed I had to use a lambert at the end! :) A white lambert isn't
exactly the same effect as the shadow pass, and the shadow pass is quick
to setup, but because of the visible faces problems, I'll use white
lamberts from now on.
So thank you Oscar for
Let me see if I understood your rendertree, you are rendering your beauty
without any shadows right? then an FG pass which you add to the beauty pass
two times, one normal and one darkened and masked with the shadow pass.
It's being a while since I've rendered in this kind of components, but

Hello Oscar, thanks for your answer!
Well, if you look at my FX tree:

I also have a final gathering pass that I darken through color correct.
Then I input it in the shadow areas (self shadow + drop shadow).
In my beauty pass, the shadow on vis
As far as I know, that has always been a problem with the Shadow node, I
think when I've had to use the shadow node, I turn off shadow cast on
visible faces, I basically have used this as a shadow catcher, why you need
the shadow cast on visible faces? that should come out with your shading

Hello Alexander,
I played again with channels and got a better understanding of it thanks
to your help and to Ola's great blog

.
So here is my last attempt at having both self shadow and drop shadow in

Your beauty pass composed from several basic channels: diffuse (or some
renderers call it lighting, e.g. vray ), reflection, refraction, specular.
So lighting channel it is your beauty pass -(minus) reflection - refraction
- specular. I assume that you are using architectural shader and don't use

Hey guys,
Thanks for the suggestions, which got me interested in render channels.
Previously, I was rendering with a pure pass workflow.
I read the doc about channels but there is no example on how to use
custom channels. So now I have more questions if you don't mind : )
But before that, her
I'm not sure which passes(channels) you rendering except this one, but I
think you can get your shadow pass from your beauty's pass lighting
channel, if you render separate pass with lighting only but without shadows
and an albedo pass.

Hello Jason,
Thanks for the help.
The steeping is well visible in my render pass' camera, not only in the
threshold but on large parts of the roundness of objects. So as I use
this shadow pass as an alpha in composting, it's annoying.
But your post made me think of other options to tweak:
- I
That stepping always occurs, (revealing object polygons without
"smoothing")

But normally isn't visible, as it happens slightly beyond the maximum
reach of the light on an object

And should similarly (nor
Hi all,
Please check this picture of a coffee cup, rendered in its own shadow pass:

As you can see, the shadows are not soft, they look weird, like
"stepped". I tweaked some shadow and area light settings, but I
