Maya Q&A - Arnold Shadow Pass

[@nievesllosa9287]

oooh really you dont know how much i have been looking a tuto like this, thank you soooooo much aaaaah

[@yonesantana]

Hi Nieves, I'm glad the tutorial was useful. Feel free to ask any more questions you might have. Thanks

[@nievesllosa9287]

@@yonesantana well if would be possible ... i have been trying to render emission lights independently (for example a good ray light and an emission object light ) into render passes (or aovs) for to edit them in post independently but the layer emission pass aov include all off them mixed ... please if it´'s possible, im working an animate proyect and we are running out of time ;;;; please help

[@yonesantana]

you will need to render an individual pass. the emission AOV only holds the glowing material but the effect (lighting) of the material appears in the Diffuse indirect. I'm not sure on the best way to combine both AOV's. but maybe you could make a render layer for each emissive object and use a material override with a 50% grey wit no specular material. If you take each render and combine it with an ADD, blending mode you might rebuilt the light effect in your comp.

Hi when I try to render as you did, i still see my plane geometry. Do you know how to only render the shadow on the plane without the geometry?

[@kyeras]

thank you so much! I am currently working on a scene and needed to have shadows separate from the mesh, and this is just what I needed!

[@yonesantana]

Glad I could help!

[@bvladimirpl]

Hi! I was wondering to do this before. Thanks for the quick and clear tutorial.

[@yonesantana]

Glad it was helpful!

[@user-qb9vk5ze5r]

Thank you , very helpful.

[@zavastrad9986]

Thank you so much for this great tutorial !! It helped a lot !!!

[@andrea_ciani]

Ooh thank you! Perfect tutorial, i had the same problem for years!

[@yonesantana]

Thanks Andrea, I'm always wondering if these shorter videos are helpful.

[@andrea_ciani]

@@yonesantana Absolutely! I think this approach makes working more easy because each one can organize liked videos, tag them in browser etc... thanks again!

[@warampanpengya8748]

Thank you,, I though have a little problem ,,,, when I rendered out, the only folder I had is the GEO one .. Do we have to render the shadow separately ??

[@titanlax5588]

You could also use albedo aov instead of that

[@yonesantana]

That is true, you can also use the Albedo AOV.

[@jamesdavis625]

Great tutorial btw, very helpful! How do you do batch renders which render out all the render layers automatically instead of rendering one at a time? Also, can you set it up for a sequence for each?

[@botviews611]

Thank you Sir! your Video was very clear, and absolutely helpful!

[@yonesantana]

Great to hear!

[@thelogicgh]

Really helpful tutorial . Is there a way to render the ground shadow separate from the character's shadow . I sometimes want to tweak just the ground shadow without affecting the other shadows on the character . Thanks..

[@paolaabril2922]

I’m having issues with the shadows, all the materials I have are Arnold materials and also the lights, every cast shadows box, the light works fine on everything but the shadows won’t appear. I’m doing this from an alembic imported shot. And I made sure all the materials are from Arnold. Any idea of what is happening? Please let me know , i can’t find help anywhere.

[@regeleionescu935]

Hello! Thank you for the great tutorial! Is there any way to render only the cast shadow without the self shadows? I mean, in your example, to render only the shadow cast on the floor without the shadows on the model itself.

[@PurpleFunkyFreak]

For that, with the "only shadows" layer visible, you need to go to the character's Arnold attributes and create an absolute overwrite for the "primary visibility" attribute. OR create an absolute overwrite for the "matte" attribute. The first option gives you the complete shadow on the ground (also what would be underneath the characters foot, for example) The second option renders only the visible shadow that the character casts

[@RainbowNepal]

Can you please make a tutorial on passes, of multiple frame...It has so simplified to me but I want mult for compositing in nuke. Plz.

[@lycanknight7184]

I tried this with a skydome and it didn't work, but I suppose a skydome is a more complicated type of light

[@twarski]

Tried multiple times even just with a sphere and grid...doesn't work for me. Wish you'd slow the talking as well.

[@WeldersFSC]

Tutorial was going well until 3:06 at which nothing but the HDRI renders, despite the scene looking good in the viewer. Aw well, onto the next video.

Great tutorial. I usually use the AOVs along with the spcific shadow AOV and it works great, although you have to be more proficient in comping in order to get the best of that approach. I have a question though..., Are you able to do substractive reflections when using the shadow matte shader?, it only do additive reflections. This is very strange because our beloved Mental Ray's own matte shader was able to do those substractive reflections and I even don't know the way to do it manually! Thanks.

[@yonesantana]

It maybe possible. Let me look into that.

@@yonesantana I know the Arnold shader can't do it. But I don't know if it's possible to create any pass that could help doing substractive reflections in comp

[@koktongang5311]

Sir, can you show how you model a character tutorial and how to add the controllers for the facial expression? Thanks

[@yonesantana]

Great question. It might take me a few tutorials to do it but that is the plan.

[@AhmetBerkTugrul]

thank you so much sir!

[@mosanaliniprabhath6930]

Help! It just renders single layer!!!

Perfect. Thanks!!

sir why not you making more tutorials on lighting p

[@madstylesnz]

Hi Yone, do you happen to know how to render light fog as a separate pass? As in I created aiAtmosphereVolume in render settings and I want to render that effect out separately like the shadows, if possible.

[@ashutoshjaiswal496]

sir can u please make this video in legacy render layer

when i am adding the objects to the collection and adding shadow matte override the render is coming completely black

Hi Vishant, Sorry but since COVID 19 I haven’t any time to be active on the channel. Sorry I can’t help right now.

[@jijivishant]

@@yonesantana no problem, i found out that you cannot get shadow without the base and the object on it, what you have to do is to keep the base and hide the objects and that's shadow pass, i did it that way. Am i right?

[@mon_tiii6981]

@@jijivishant hi ! What is the " Base "?

[@jijivishant]

@@mon_tiii6981 Base is the object on which your main subjects are kept upon, without it how will the renderer calculate the shadows.

[@mon_tiii6981]

@@jijivishant OKay but i don't understand what object we need hide ? the subject on the shadow matte ?

Hi! just wnna know if you have premium tutorials that can teach us how to create multipass rendering in animation and the integration to AE? i would be gladdy to purchaseb that if u have?
