Can you screenshot your scene and upload? Maybe one of your object sidebar/menu as well?
you have the proper lighting I assume?
AE any objects cloned or instances?

What is the purpose of having two reflections?
Can you give an example of when this would be useful to have two for a material?

I finally figured out how to use the shadow pass as both my beauty pass and the shadow pass layers in After Effects, since the beauty pass is baked into the rendered frames along with the Alpha channels.
I am just trying now to figure out how to have objects catch shadows but NOT cast shadows onto other objects. My 3D objects I made to match real objects in my 2D footage are casting shadows on other 3D objects. I just don't want to have to remove extra shadows I do not want for my After Effects composition.

For example, if I want to have a 3D ball thrown across my footage, I want the shadow to catch onto objects in the scene that I make 3D objects to represent and catch shadows, but I don't want those objects to also cast their own shadows on the ground.
I ONLY want the ball to cast shadows. How would I do this?

Will the option be added to the Object Tag later?

Thank you.
It was strange because increasing the colour to slightly more purple did make it purple. I did not try other colours' intermediates.

Is there any reason my purple colour won't render as purple?

Also, this website no longer has https, and chrome keeps giving me warnings. Will this be updated soon?

Why don't the light types work such as square spot, parallel, and IES? They don't produce any light in the scene.
I am trying to make a light that will look like this.

I wish to have dynamics play out and at times to have some objects disappear behind other objects for compositing.
For example, I have a 3D ball be thrown over a fence from a 2D video. I would usually place a plane the same size and shape of the fence that would only hide objects that pass behind it when obscured from the camera view.

I found a way to almost do this with centileo, however, I get some odd reflection from nearby objects I cannot get rid of.
I have a plane I made into a shadow catcher to block this tank, as an example, and I want to hide the tank (or any object that is also behind that plane). I get my result except look at the soldier in front of the plane; he is casting a reflection I cannot get rid of. It is not a reflection property on the material (I removed that and it did nothing), and changing any setting under the diffuse does not remove the reflection.
Any ideas?

I would normally apply a shadow catcher to a plane like this and use a compositing tag to hide the object from camera.
I tried having no HDR Sky to light the scene and there is no reflection anymore, and the object is invisible behind the plane. So it is something with the HDR.

EDIT:
by going to the HDR sky tag and putting matte shadow weight to 0.01 (0.00 removes the plane and makes it totally black but not invisible) I am able to get the plane to be invisible as well as any object behind it.
There is still a small outline of the plane in AE, but I can maybe manage. A tag to uncheck and makes things hidden from camera would be nice in the future.

If you don't need a background then additionally use HDR Sky setup + transparent background in render settings. Everything is exposed in render settings.

Are you able to change the default settings for the light and sun light objects? It would be good to have them produce light when adding them to the scene initially. The light object begins too small for it to light anything in the scene, and the sun light starts off in a state much too dim as well and in a position where it doesn't light anything at first.

Kirgman wrote: Why you background is red? Why you don't do it with ground plane + shadow catcher that can be transparent with semi-transparent shadows?

this is after I rendered it and put it into AE to see if it was transparent.
I need to be able to change each layer separately so i can reduce shadow opacity and not affect the beauty layer.

When I tried multi pass non of the layers other than the Alpha were transparent backgrounds. Is that because of using separate alpha?

Ok.
I think I wasn't using HDR when I tried multipass before. And I kept thinking I needed the shadow multipass added.
I will try to make that work and also the sky override you mentioned.

EDIT:
That does not give good results for me.The beauty pass does not have an alpha and so the background is no longer transparent. So I will just have to not use multipass for my composites.
Also, the alpha layer it gives me has shadow all over the plane and not just where the object shadow should be.

The first image is what I get with your multipass settings, and the second is the one I did before without using multipass. It is better as it only has shadow from the object.

Kirgman wrote: Sel ect "Transparent background" option in render settings to make transparent image. Actually it's a responsibility of Cinema 4D to save the image layers that renderer produces. Maybe PSD will get a separate Alpha pass? Actually PNG when saved has alpha, I think it can be extracted in AE. Currently I can't look into AE.

PSD and PNG did not work; they did not produce alpha layers in the saved file.
OpenEXR did work, and I could extract the shadow in After Effects. I needed alpha channel and transparent enabled as you said.
To get the beauty pass to work I needed to keep alpha and transparent but disable the plane from render view.

I'm just trying to figure out if it is possible to render my beauty pass with the plane object invisible but still have it provide reflections if I have a texture applied to it to simulate the ground I wish to composite the object onto.
I tried the C4D composite tag and disable 'seen by camera', but that did not work, the plane was still visible. I am trying to get lighting and/or reflections cast onto the object from the plane with the plane still invisible in the render.
These images are what I mean. See how with the plane visible it casts the reflections, but with it invisible those reflections are gone. I want to keep those.
is there a centileo compositing tag planned in the future?

Sorry, I scrolled fast on my phone and missed the first reply.
I will try this tonight.
Thank you.
And I assume I can render the beauty and shadow passes completely separate and alone on individual renders?
I usually like to render beauty composition first and then shadow once I'm satisfied.

EDIT:
It is not letting me save only the alpha channel.
Every time I try to save it just saves the beauty pass layer for the image and not the alpha.
How do I get it to save JUST the alpha channel to use for shadows in a composition?

These images are what I am trying to do in centileo. One is beauty pass and one is shadow pass. How would I render just the shadow pass?
The only thing I can do that is close is to render a multi-pass and extract the shadows in After Effects, but it doesn't let me have a transparent background because I need to have the HDRi camera brightness set to 1 to get the alpha to render and create a shadow.

One only has material editor while the other has node editor. And the centileo material has 'matte' while the material [node] has shadow catcher. I tried both material types and neither give me shadows in the render. Just material is the old version of CentiLeo materials that was the only option before Cenima R21. Since then Maxon has added node based materials support for 3rd party renderers and we have made the implementation and exposed it into the main menu instead of just materials. "Matte" and "Shadow Catcher" fr om both versions mean the same thing, we have just changed name in one place forgetting to change in another one. You probably don't see shadows if you don't setup HDR lighting. With no any lighting it's black. Just learn from our sample.

I was using a centileo sun light to light my scene, and I will try again, but I am pretty sure I tried an HDRi light as well and it didn't work.

Will it not work with simple lights at all, only when using an HDRi?
and which sample do you mean? Wh ere can I find that?
When I used the shadow catcher for the material node and looked at the node editor, there was nothing there about shadow catcher. Is that normal? Shouldn't there be some node reference to it?

I cannot get shadows to render at all. I tried shadow multi-pass and it just renders a black screen.
I enabled 'Alpha channel' and added the multi-pass for shadow.
I have tried just about every combination of render settings to try and get shadows to render, but all I get is a solid black image.
What do I need to change to get shadow pass to render, or is this broken?

Also, I see that there are two types of centileo materials: centileo material and material [node]

Kirgman wrote: Have you realiszed how to make shadow catcher? So, assign a material to a plane where you want to get shadows drawn on a background. This material should have "Matte / Shadow Catcher" flag enabled in node-based materials. In different material implementations (node-based or not) there is either shadow catcher or matte name for this. Also you can cast the shadows with different shadow intensity to this plane object from other scene objects. This shadow intensity can be controlled for Sky + CentiLeo environment tag, for Directional / Sun light source or Omni light source with CentiLeo light tag. In all light tag settings "shadow catcher" value changes the shadow intensity.

No, I cannot get shadows to render at all. I tried shadow multi-pass and it just renders a black screen.

This is very useful for making the ground render as alpha so I can composite objects into after effects. I hope this feature is available now or soon, or it is a deal breaker for me to switch to this engine. I'm looking forward to starting to use this centileo. Also, I need to be able to catch shadows on the same ground plane and render out a shadow pass. Is this possible? It seems all you want is possible right now. Just make a ground plane, drop a material with "Matte / Shadow Catcher" option On. Swich on Alpha Channel AOV - and it will render shadows on the plane, but will not show the plane in alpha channel. Also you can use Sphere (Omni) light sources or HDRI Sky with Shadow Cacher intensity to change the strength of shadows casted on matte/shadow cacher object

I tried and the render just shows my objects with no shadows on the plane and nothing else. It looks just like my regular beauty pass. I enabled alpha channel like you said, but it does not give me any shadows on my plane when I render a shadow multi-pass.

How do I make shadow pass work?
Also, whenever I render a multi-pass it still renders my beauty pass. How do I make it only render the multi-pass I want and not the original beauty pass? Doesn't this would waste a lot of rendering resources and increase rendering time?

But will do this in the future, there will be a lot of flexibility there because CentiLeo allows to render a lot of render buffers at once and keep really many images.

ok. I do not need the feature too much right now. As long as I can figure out shadow catching with centileo to composite rendered objects I will be fine for now.
thank you.

I tried and I cannot get the buffer to have anything rendered. Only the alpha channel looks like the buffer should and the buffer is just a black screen.
My buffer is applied to only one object, but the alpha shows all objects as white. I need the buffer to apply to a single object. And taking this saved frame doesn't allow me to have an alpha either way. When I use it in After Effects it is just the regular image with the objects looking normal. No alpha.

I don't want alpha channel, so is there a way to get object buffer to render properly?

Kirgman wrote: ssjenforcer , open CentiLeo render settings, there is AOVs tab. In this tab please make "Alpha channel" flag enabled. So, in IPR you will see the Alpha chanel buffer together with Beauty image. Also in Picture Viewer there will be both Beauty and Alpha images.

ok, thank you. I will try this.
I think I disabled that after realizing I didn't need it for compositing my Beauty pass.

I am trying to get a luma track matte for an object to render out and use with After Effects. However, I have tried many variations and types of formats for rendering (EXR, PNG, etc.) but I cannot get the render to give me a multi-pass with a luma (white object on black background) to use.
I used the C4D composite tag which has object buffer, and I added object buffer to multi-pass with centileo render settings.
Am I doing anything wrong?
My object buffer 1 pass in the render is just a black screen, but there should be an object with the buffer in a tag.

I followed this tutorial to do it. https://www.youtube.com/watch?v=mycLyM2oU_c
