Tripod Tracking in Blender - "Spaceship" landing (Patreon)

Just wanted to throw this info out there! Been seeing a few people struggling because they're effectively trying to get a 3d track out of 2d movement- it's a super easy fix, though! 

ALSO- I suppose I ended this tutorial a bit prematurely, because while this all works in the viewport, if you actually want to export it out of blender, you'll run into some small problems- mostly just that it automatically applies an undistort node to the footage, which makes it not match the branches on the plane we added.

This is solved super simply by just deleting the undistort node in the compositor!

Can we have the footage to try it out..that is a neat trick using image texture and wrap it around as an hdri map....i think if i track more couple of times i will understand blender tracking workflow.....there is some i want you to look into..... Blender Photogrammetry Addon v1.0 (Download: https://github.com/stuarta0/blender-photogrammetry/releases/tag/1.0 ) https://www.youtube.com/watch?v=hk5ovQ6-IbM

2.80 that allows conversion and processing between a number of photogrammetry formats, in addition to providing dense reconstruction straight from Blender's camera tracker. since you love photoscan and photogrammetry ..hope this will help you in anyway...plus i cant get my head around it ...am trying to figure it out....

Ah, yeah here's the footage! https://drive.google.com/open?id=1VSmggX76w6NcXVmRvEF5CBRRyMsvLNw6

Ooooo- that looks pretty handy! Yeah there's a lot of overlap between motion tracking and photogrammetry. You generate a dense enough point cloud, then convert it into a mesh and project a texture back on it, and hey hey! Sergey (the guy who programmed the motion tracker back in the day (single handedly? I'm not sure)) said it would actually be pretty easy to get the tracker to do that final step- it'd be really cool to see if it ever happens!

I did not know you could composite in the viewport like that #mindblown

Brilliant.

Thank you for the nice tips! Can you please tell us more about the render phase? I've been struggling in Evee and Cycles for rendering my tracked scene, looks like the settings aren't the same for those render engine.

Oh no, a borg cube! I learned some new things, great video.

Very Nice. Sorry for asking a beginner question, How do You navigate inside the Camera View? Keys please..

Hey Ian in your blender conference talk you talked about generative box mapping this greeble cube from nasa. Didn’t quite understand what you meant by that. Could you elaborate :)

thw default cube is coming for revenge

awesome, thanks again Ian!! do you know anything about the possibility of having a shadow catcher with Eevee? or will you make a video on some more universally applicable work around, than the highly specific ones i see on the web, because you have some awesome shadow catching in the movie clips you uploaded :)

and since you said you ended up leaving the render in eevee because it looked so good :)

I haven't played around with it yet, but this tutorial looks like it could work?? Not as easy as the checkbox we have in cycles, but hopefully we'll get one at some point! https://youtu.be/2WYCZGOCPEY I still mostly use cycles personally, except in the one big 2 minute "Dynamo Dream" teaser, and I think it's probably still a bit more suited to compositing.

Oh! Yeah totally! My key casting wasn't working (gotta figure that out)- but there aren't many, and I say them out loud: https://youtu.be/ucLBU3yGQQY

>>34409686

Oh! Yeah, that was more just me talking about what I used to do that... wasn't good, hahaha- here's a better breakdown: https://youtu.be/ZYzWH2FF-90

Thanks for the video reply 🙋🏼‍♂️. Haha interesting method of texturing. Thought you were talking about something completely different.

Amazing stuff Ian :)

IanHubert
>>34406981

It's true, yeah! Cycles is still a bit more integrated into the compositing pipeline (like Raoul was mentioning below, there isn't a great shadowcatcher option in eevee yet that I know of). IDEALLY a lot of it is already set up when you click "Set Up Tracking Scene"- (in fact oh jeez I just pieced a couple things together, haha)- it sets up all the layers and such in the compositor, so you can just click "Render" and it'll comp it on top of the footage. What type of stuff are you trying to render??

you made me in love with project from view...hahaha lol

IanHubert
>>34409686

It's so good! Usually just plain "Unwrap" will give you the same result, but there's something just kinda nice about, "Hey see this right here. Give me this in the UV editor. No funny business."

This is sooooo helpful! many thanks!

Thank you Ian! I mostly use Cycles too, and of course it creates nice renders, its just sometimes I dont have the time to wait for a render to finish :)

Good call with creating a fresh shadow catcher as the first one regularly dunt work as expected.

IanHubert

Honestly I woke up in the middle of the night slapping my forehead. When I did my first test, I couldn't get the generated plane to render as anything other than black and figured it was best to delete it, and I realized way too late it was the shadow catcher object for the compositing pass, and I probably just confused everybody (including myself), hahaha

WOW this is way easier in blender then in D. Resolve bro thanks here's my 7$ lol thanks

Dude. You are like, AMAZING.

I'm having trouble rendering the background footage. In cycles all my other elements are in the render except my background video. In Eevee however its rendering the video. Im an Idiot. I wasnt waiting for the other render passes.

Anonymous

I'm sure this has been mentioned somewhere but I'm new here and a tad new to blender as well. But in terms of compositing into some footage that has a touch of fog in the air, how would you go about matching fog levels on objects that I'm trying to put into the scene that are varied distances from camera? (without affecting the footage obviously) I attempted to do it the way you suggested with the city tutorial and emission layers to sculpt the depth of the city however, the emission layers always blow out the background image for me) I wonder if I should be thinking of a completely different way of doing this. Thank you so much!

Derp, I have the same question. How did you resolve this? The background footage isn't in my render, and the only suggestion I can find online is to import video as plane and use it as the background.

Anonymous
>>35075348

Honestly I just waited. The 3d elements were being rendered first and as soon as it was done i was closing the render. I wasnt waiting for the second pass. Sorry I cant be of more help

i always wanted this... ian Thanks a ton!

This is so good. I tried to do this but for some reason the footage in the 'window' plane seems slightly off sync! Could this be due to a not 100% perfect track? Oh, and is there a way to add motion blur to everything except for the footage in the window plane?
