You're a lifesaver. I can't even begin to tell you how many of your tips I've used!

[OccultDemonCassette]

How did you learn so much about Blender? It's an amazing wealth of knowledge .

[evanbarron]

And the background will still be reflected on the surface of the foreground object? Holy crap

You can apply this method to a moving camera if it is a nodal pan/tilt/roll only, and limited movement. Render a wider field of view for the background to encompass the degree of movement within the desired frame. Then apply the camera movement to the still image in the composite by reverse stabilizing the background image. This method was applied extensively on Tim Burton's "Alice in Wonderland" to save time on background renders.

Good idea if you don't need bounce lighting to work between the object and background.

I've tried this before but the shadows on the shadow catcher is noisy. I read somewhere that denoising in blender does not work on the alpha channel. Is there anything that can be done to sort that out or should I learn to use the compositor😁?

[isaakvanwegen]

What about reflections on the background?

[GeoNosiS]

Trying this with my scene actually made it take more than twice as long to render one moving object with the background hidden. Weird.

Plz make more video on blender animations

[pile]

Nice. I think I used that process to make some animated gif.

How would u do this if u have volumetrics? Like I want to keep how the volumetrics interact with the foreground object

[letsgobirding]

can you also set the background as a still background image inside the camera? Then the compositor will autopopulate the node arrangement for the background for you (or is that slower?)

[marcelosantos]

Saved me only like 2 seconds per frame :/ the problem is that the denoiser is still trying to denoise the transparent parts, I'm pretty sure that no shadow is appearing in these parts and yet it tries to denoise, is there any way to solve this?

[anarkijex]

what if your foreground object emits light to environment?

[mahjari]

how to render animation exr with out floor in  blender to nuke.
I want render OpenEXR Multilayer sequence, with shadow chatcher.
Please  can you make tutorial

Hi Jan! Cool scene. Is it possible to download it?

[albertjingfors]

I'm pretty new to blender and I noticed that alot of the shapes in the animated model did not show in the object view above. How do you do that and how can you use it when modeling?
