@@YouAndMeAcademy thank u great explanation, btw to enable reflections on ground i need to add RS material shadow catcher to the ground plane, let us know if there is shorter way. And 2nd question if I use Dome as bg color without HDR how can i add radial gradient color to it? like center is lighter edges are darker color like vignette. Thanks in advance.
Hi, I want to know that how to get the shadow with the alpha channel? Should I render two times? Or is any way can do it in the AOV? BTW your channel helps me a lot! Thanks!
Hey there, all you need to do is click the Affects Alpha Switch and it will cut out everything but the Alpha. I hope this helps, thank you for the support!
Great video, any idea how to do this with a transparent background? I have a single object on a plane with a shadower catcher but the square always renders out as a black plane whenever I switch the background off in my dome light!
@@Bingleheimer weird isn’t it. I now just Chuck a shadow AOV on every render which is annoying but works I guess. Really don’t know why it’s not possible!
This becomes a lot more complicated if you're using a camera tracker. The video seems to be overridden by the tracker and will only display the first frame. C4D 2023 / Redshift 3.5.09.
great tutorial thank you! i was wondering, taking your scene as an example, how would have the plane catch the shadow of the shoe only, but none of the other objects shadows? i am assuming it has to do with excluding/including the spheres in the object tags, but i can't figure out how to make it work exactly. thank you!
Put a redshift tag on the object you don’t want to have shadows. Then under the Visibility tab uncheck Cast Shadows. Good luck and thanks for the support!
A lot of times the object casting the shadow will cast to the edge of the shadow catcher. If you just scale up the shadow catch/disc then it should not reach the edges. This is because the further moved away from the object the less the show spill happens. Thanks for the support!
The most frustrating thing is it works only with Sky Dome backgrounds. I would like to be able to put a plane behind my object, then play with lights, but that is not possible.
How do I catch reflections too? I know you can do it with the legacy matte shadow catcher material but I can't figure out how to do with the RS tag technique you showed.
What should I do if I also have a puzzle matte? How can I save the shadow together with the puzzle matte? I actually doesn't show the shadow on the red channel of puzzle matte.
Unfortunately that is not possible, you will need to take your shadow pass and then matte that out with a puzzle matte in AE, Nuke, etc. Hopefully that makes sense.😉
Uff da. Trying to show a shadow on a transparent background seems to require Visibility override enabled, and on the matte tab enable affect alpha, and setting the alpha to anything less than 1.
@@YouAndMeAcademy important notice, I'm used c4d "floor" object, unfortunately it can't be a shadow catcher, so all of your instructions are working on 2.6.41
I’m having trouble figuring that out. Any chance you’d do a video? I think a lot of people would benefit. Or if you happen to know of a video that teaches it :)
Yeh nope. It makes the square disappear in the preview, but in the render, it's just a big 'ol black square, having done nothing. No shadowing, nothing, just a black square. When I click "Enabled" in Shadow under Matte it does literally nothing. Click it on, off, back on... no difference, nothing. Black square.
If you would like for only the shadows to come through in the alpha, you need to check "Affects Alpha" under the Redshift Tag/Shadow. I hope this helps, thank you for your support!
Hi Steven, if you can give me some details on what is not working I can try to help you. Or you can send me the project file and I’ll have a look. Thanks for your support! 🤜🤛

so happy i bumped into your channel, you need to advertise this channel, already subscribed!!

This is not possible unfortunately :( Hopefully soon.
Really? This has to be a thing.

sometimes I can see edges of the shadow catcher plane. .. is there a way to fade edges? so it blends in smoother with the background?

It’s not possible to my knowledge. You need to render an AOV for the reflections.
What should I do if I also have a puzzle matte? How can I save the shadow together with the puzzle matte? I actually doesn't show the shadow on the red channel of puzzle matte.
That is not possible, puzzle mattes are for comp and are meant to be a post effect rather than baked into your renders. I hope that makes sense 😊
@@YouAndMeAcademy Oh got it! How could I get the shadow to add to my render though?
Unfortunately that is not possible, you will need to take your shadow pass and then matte that out with a puzzle matte in AE, Nuke, etc. Hopefully that makes sense.😉

Not working for me, shadow just don't appears
Hi Jason, it’s most likely a versioning issue. Which are you on?
@@YouAndMeAcademy important notice, I'm used c4d "floor" object, unfortunately it can't be a shadow catcher, so all of your instructions are working on 2.6.41
Is it possible to export the shoe with the shadow, without the plane?
No. You just need to render it with alpha and then in comp use the alpha to cut it out 😊
thanks! my plane is rendered as well how to disable it in final render?
Turn the check box that says "Affects Alpha" Thank you for the support!
Does this only work with REDSHIFT? I am a Houdini user with Mantra. Cheers.
Hi, yes this lesson is for Redshift. Thanks for your support!
Do you have a tutorial on how to render just the shadows in Redshift?
You can render a shadow AOV pass then comp it in.
I’m having trouble figuring that out. Any chance you’d do a video? I think a lot of people would benefit. Or if you happen to know of a video that teaches it :)
@@nickwallace-maverikfilms7563 yeah good thoughts! Let me see what I can do.
my plane doesn't disappear like yours in the RenderView R20
Hey there. If you send me the file I will take a look for you. You can email at www.youme.academy. Thanks for your support!
this "new improved" solution doesn't render out reflections on the floor, which I need.
Hey Tim, there’s a simple solution for that, render out an AOV pass of your reflections, then add it back in comp.
Yeh nope. It makes the square disappear in the preview, but in the render, it's just a big 'ol black square, having done nothing. No shadowing, nothing, just a black square. When I click "Enabled" in Shadow under Matte it does literally nothing. Click it on, off, back on... no difference, nothing. Black square.
Hi Christopher. If you’d like to send me the project file I can take a look for you. You can email via the website. Thank you for your support.
Did you find a solve for this. Running into the same issue.
usually cracked software problems :)
Hi! When i do my render this way, shadows seem work fine for RGB, but when i go to aplha, it all just messed up. Any ideas?
If you would like for only the shadows to come through in the alpha, you need to check "Affects Alpha" under the Redshift Tag/Shadow. I hope this helps, thank you for your support!
Not working at all, my plane just turns black?
Hi Erik, if you’d like to send your file I’d be happy to look. You can email the link at www.youme.academy. Thank you for your support!
@@YouAndMeAcademy Thanks for the quick reply and the effort, i found a solution with the shadow caster node, way easier ;)

thanks, couldn't get the shitty shadow catcher material to work

@@YouAndMeAcademy nah I mean your video helped me cuz I couldn't get the shadow catcher material to work but using redshift tag did the trick
Ok glad to hear 😊
Simply does not work.
