Hey Everyone! In this video I show how you can use basic camera projection in Blender 3d to integrate CGI into live action more effectively. I use this technique a loot especially when I don't have a proper HDRI of the environment the shot is from. Enjoy and let us know what you would like to see next!

THIS IS ONE OF THE MOST RARE TUTORIAL WHICH I HAVE EVER SEEN ON UA-cam... THANK YOU MAN 🔥🔥
Thank you! Appreciate your enthusiasm!
I learnt the basis of camera projection within the first 3 minutes now I just need to see the rest for the tutorial. Could never ask for more. So dope and detailed
Glad to hear it! Understanding the concepts are key for certain techniques before practicing them.
@@LightArchitect yeeaaah
This is so useful! Thanks for making these Blender and VFX videos on your channel! I'm surprised this isn't even more viral!
I know! I'm upset this doesn't have at least 1,000,000,000 views.
Honestly, you deserve more subs and support man ! Love your tutorials. Have been helping me to learn so many things. Subscribed !
Thank you! Glad to help! Hopefully as we get more subs we'll be able to make even more content for everyone!
Like first then watch :D
Thank you! 🙏🙏
Excellent Work, thanks for the Great Tutorial, Legend!! :)
Thank you so much! Glad it was helpful!
Love it. Simple yet effective. Would you recommend doing this for every shot that uses live action footage or just when you don't have an HDRI?
Thanks! I would say most cg that is added to footage generally needs some kind of digital environment built around it. For things that are flying up in the air I often just use an HDRI...but for objects on the ground I tend to build these projections a bit more for more realism. Sometimes you can get away with just colored groundplanes. Depends on the material of your CG element too.
@@LightArchitect Makes sense. cool.
very helpful!
Thanks Hubert!
Thanks!
You are welcome! Thanks for watching!
Dope explanation of your cam projection workflow in #Blender . Thanks alot, great work. Cam proj. is such a timesaver. #3d #liveaction
Thanks! Yes 100% it is! Saves a lot of memory too.
@@LightArchitect Oh yes my friend! memory and money. :D

топовый туториал, огромное тебе спасибо, теперь мои работы станут легче и качевственее в производстве, multumesc inca o data
very cool!!
Thanks Bhargav!
Tutorial starts here: 7:54
Very nice. Thanks for watching Panu!
Great tutorial! Have wanted too learn this for a while. Feel like the video could have been like 1 minute though lol
Thanks! Yes this technique is super useful. Yeah maybe the video could be a bit shorter but hopefully it gets the idea across. Thanks for watching!
Great tutorial! Quick question.. would this projection capabilities able to apply the same principal .. for instance i have a still image of a metal barn... with some grass in the foreground. The director wants to do a timelapse on the ground...
Hi Steve. Thanks for the kind words! In answer to your question yes the example you mention is another huge use of camera projection. Its a really powerful and simple concept but also has some limitations.
You will probably find our video here useful for the effect you are referring to: ua-cam.com/video/ua8CrGf6wP8/v-deo.html

Thanks bro
For sure!
Aren't the reflections of the sphere gonna be distorted if the texture is only unwrap for the camera view?
True. If the camera moves side to side too much then this will occur. But its still an effective technique to use a lot of the time.
Hi, why is the alley ground treated uniquely as background shader? Shouldn't all the recreated geometries be shadow catchers? thanks
You rule
Thanks ViB3! Lots more coming soon!
Thanks for the tutorial.. Buti have a doubt ... Whatis the need of camera projection .. .. We can directly add cg objects by keeping the video as background after the camera tracking is over ... Kindly explain me.
Hi Hawaijar. Thanks for the comment. The purpose is usually to have more realistic reflections and lighting on any CGI objects added to your shot. Hope that makes sense.
@@LightArchitect oh thanks buddy
@@boinao8046 You got it!
Hey, great tutorial. I have just one problem - turning off shadows in Ray Visibility for the "reflection" assets doesn't seem to do anything. They're still casting shadows! Am I missing something here?
Why you put hold out for background? it would be batter if you set it as disabile from view layer. If you set it as hold out it became black/empty. Isnt true?
is there's any way to have a long tutorials i mean with details , paid ones
Hi Fantasy Zone. Possibly in the future. We also have a Patreon option available if you would like one on one consultations with anything. www.patreon.com/lightarchitect
idk why the layer system doesnt work for me,
i select my sphere and for exemple, turn off the camera visibility on the shadow layer, when i go to the foreground layer, the sphere still camera visibility off
its kind of not independent setups :/
anyone can help?
Hi Bird, Camera ray visibility is global. So it will effect all view layers. The holdout and indirect only restriction toggles effect only the view layer selected. Hope this helps.
Please add footage for practice
can't you project an video and bake them on the planes created?
Hmm good idea. I have never tried it but theoretically that sounds right.
Man, how u got the shadows interactions on the walls if you use the walls as an emissive texture?
Good question. You have to use different view layers for different data passes. That way one of them you wont have the walls emitting light and effecting the shadow passes. Thats how I do it anyway. I'm not sure about others. Did you figure it out?
Does anyone know why when I use cycles, a texture environment and an image as a plane, it does not emit a shadow, it probes by removing the texture environment and illuminating with lights and it works, but when I activate the hdri it does not emit a shadow, any solution please?
please add footage to practice
Where you take hdri maps
?
Usually you take the HDRI map from the same position that you want to put your cgi object in your scene. Here is a video explaining: ua-cam.com/video/etOkgjrTfa8/v-deo.html You can also download some basic HDRI's online but they won't match your environment exactly. Hope this helps!
@@LightArchitect thanks!!!
