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.

Does "object buffer" not work with centileo? (multi-pass)

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.

I think I disabled that after realizing I didn't need it for compositing my Beauty pass. |

For sure we need to implement the complete support of composite tag, this is very important. And also implement a lot more AOV/extra render buffer types. This is in a roadmap and not really hard to do. But currently are doing other important things

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?

I understand the problem. At the moment the selection of objects to get included into alpha channel or object buffer or any other mask buffer is not supported. 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.

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.
