Handy trick you may or may not already know, if you drag down on a value box you can select and change multiple values simultaneously. It also lets you type the value in! Hope this helps :)

song shi

That's awesome

Zeke Faust

Congrats on getting into Resolve! That's music to my ears ;D It really is an amazing tool especially as an end to end pipeline. One thing I'd suggest is buying the studio version of Fusion. It's so much faster and more stable than the module that's built into Resolve, not to mention you have OFX support and all the extra bells and whistles like the camera tracker, optical flow etc. They even have a dynamic link type feature where you can send shots in the timeline to Fusion with a click! Doesn't have the excitement of the "free" label, but at least it's only a one-time $300 for a perma-license. Unlike Adobe who wants to squeeze you every month.

IanHubert

OH HEY!!!! That's super useful! Thanks, Ethan! :D

IanHubert

Thanks Zeke!! Yeah, I'm loving it. Still has some quirks (especially when it comes to exporting EXRs???) but it actually feels like modern software instead of software from the 90s that they keep stacking more stuff on top of (Naw, Adobe's cool- there's just certain corners where you can kind of feel its age (and I found my old Premiere disk from like 2002 yesterday and felt unexpectedly nostalgic :P)) And ooo- I got the studio version of Resolve, I think the studio version of Fusion comes with that? Although! The dynamic link stuff is standard even with the free version of Resolve, now! I need to familiarize myself with the camera tracker more, but the planar tracker is a DELIGHT. Only just learned a basic color workflow a couple days ago (toggling between a global adjustment layer and easily jumping around to tweak specific clips is totally rad). But yeah yeah!!! Between Resolve/Fusion and Geometry Nodes it's been a month full of really exciting new stuff! Also I'm very ready to do something that doesn't involve learning anything.

IanHubert

LUKA what if it's a very bad tutorial you will be SO EMBARASSED.

Luka Hrgovic

Crap, I haven't thought of that!

Zeke Faust

What kind of EXR exporting quirks you having? I always found the workflow to be pretty smooth in resolve/Fusion. Happy to help if I can, I transitioned from AE like 6 years ago so I've gone over the roadbumps. Re: Adobe's age, YES. This is my biggest issue. After Effects has only gotten slower and less responsive with each update, and it's at the point where it's literally become unusable for me. Resolve does indeed come with a Fusion studio license, so it sounds like you're set (that planar tracker is honestly better than mocha most of the time). As for your last point, yes - Learning is fun, but having learned is even better, lol.

IanHubert

Oooo- the first was that if you export at any resolution other than native the alpha gets CRAZY (some premul/straight mixup, I think?). Also, could *potentially* be a blender bug, but I have to interpret the colorspace as sRGB when I import the exrs into blender, when I *think* EXRs should basically always be linear (right?) oh and the fact that if you're in the wrong mode (individual/video or something) it'll just straight up ignore any time effects you've applied in the timeline (reversed a clip without much motion in it, it exported forwards- took me forever to figure out why it didn't line up with the tracking anymore :P). A lot of which COULD be user error, except the first one seems solidly like a bug, which has made me less quick to blame myself. You ever run into any of that? I found a combo of settings that worked good for me, I was just surprised how much trial and error it took. But hot damn yeah, fusion's planar tracker is SO MUCH NICER than having to hop into mocha. Just grab the planar track, drag it into whatever you want to move that way. So intuitive :D And the integration with the color tools is fantastic!

Sariminator

Sorry Ian don't believe ur excited about this, there's no exclamation point in the title 🙄

Robin Ruud

I love seeing you get into geometry nodes! I'm sure it'll be super useful for scattering things on your environments too!

Nate

Fantastic tutorial! I really had no idea where to begin with Geometry nodes so this was a perfect intro! Also the shots from the new episode are mindblowingly cool! Can’t wait to see more!

Frederic Gobry

Even though the new geometry nodes are better than the first iteration, I'm still confused by things like the normal node: what drives it (around minute 13)? shouldn't we somehow provide the object/face/... the node returns the normal of? Right now it feels like the node peeks into the object that _uses_ the normal, and poof, it gets the domain over which to evaluate the values...

PaulWGraham

Cool tutorial. To your point of mostly only Python people enjoying your Python tutorial. Programming can be a skill that's tricky to learn so it makes sense that your Python tutorial would attract people that can already program and are looking to get more from a tool they already have in their toolbox versus people that don't know how to program at all. My personal point of view comes from the other end of the spectrum. I'm a programmer that just can't seem to grok Blender. Yet this particular geometry node tutorial was easy to understand. Aside from the fact that nodes are just programming by other means I think another aspect that made it accessible for me is that the node editor constrains Blender in such a way that it's easy to form a mental model of what's going on. I can understand the problems I'm seeing and infer the existence of a solution. Whereas Blender in general is a impenetrable bag of disconnected stuff.

PaulWGraham

Also, as an aside at ~15:00 in the input field of the value node you divide the #frame to scale it's value. If you are comfortable doing math inside input fields* there are two other math operators I recommend you check out. The first is the modulo operator represented by % in Blender. The modulo operator returns the "remainder" of a division operation. For example: 4 % 3 = 1 5 % 3 = 2 6 % 3 = 0 7 % 3 = 1 8 % 3 = 2 9 % 3 = 0 Notice the repeating pattern. Now think about using the modulo operator with a value that constantly increases like #frame. The second operator you might want to check out is the "floor division" operator represented by a double-slash // in Blender. It takes the result of a division and rounds it down to the nearest integer. For example: 5 // 2 = 2 4 // 3.75 = 1 .34 // .11 = 3 The main advantage of using floor division in this context is that the operator will always return an integer. * Which I don't necessarily endorse because my guess is that if you are already using nodes you should probably stay in the language of nodes to make it easier to understand what's going on if you ever have to revisit the node graph but I don't really have the experience to know for sure if that's actually a problem. https://www.geeksforgeeks.org/what-is-a-modulo-operator-in-python/ https://www.geeksforgeeks.org/division-operator-in-python/

Peter Mackey

This is great! I used a similar setup with the raycast node for a holographic display of the ground terrain. Looking forward to seeing your Resolve workflow. I use it for grading video but without an OCIO plugin I always find the colours and gamma go weird with Blender EXRs.

Zeke Faust

Also if you're coming from AE my buddy Millolab has tons of macros on reactor that emulate classic AE effects, like roughen edges, refine matte, and turbulent displace to name a few!

Mystah TV

random question, how much time does it usualy takes to render a scene like this? Im guessing a lot, so do you have any tips on how to preview to have a good idea about the final outcome?

Zeke Faust

This is because EXRs from blender don't bake in the view transform, revealing the scene referred linear data. You can use any number of transforms in resolve to get the look you want, be it an ACES transform, RCM, blender filmic (if you use an ocio plugin as you mentioned)! A color space transform node with tonemapping and gamut mapping enabled is a simple way of getting a nice out of box result with exrs from blender

Solstice121

You suckered me into using geometry nodes, and of course in traditional Ian Hubert style, it's the best tutorial I've seen.

Miko Dela

I started using geometry nodes recently, and I knew most of the technicalities you shown, but I'm still deeply impressed by your creative process, and the fact that you're able to just jump in and mess with stuff until it fits your vision, which always goes deeper than I expect. I mean, I often think "oh, this looks pretty nice, I guess that's it" and then you say "no, we'll add CONES! AND THEY'LL JUMP!" and it turns out even cooler :)

Zeke Faust

I keep trying to answer this and it keeps auto deleting!? A spam flag maybe, so I sent it over on discord

Sam Schippers

I love After Effects and I’ve been using it for years but as the projects I’m working on start to get bigger I’m finding it’s performance is not quite there for me 100% of the time. Unsure yet if I want to move into Nuke or Resolve. I’ll just really miss my plug-ins I’ve built up over the years

Zeke Faust

Resolve (rather Fusion) is a great place to start learning, particularly because it promotes a greater understanding of the fundamentals of compositing IMO. Plus, you get unlimited updates and unlimited render nodes. On the other hand, if you deeply hate 10,000 of your specific dollars, NukeX is a great way to get rid of them at once ;D (I know there's nuke indie, but it has some big limitations)

Simon Salord

Yeah! I'm happy to see you diving into geometrynodes! Your excitement about it is a pleasure to me. I see you used the hold method (#frame) but since B3.1 there is a node called "Scene Time". BTW, you don't necessary have to use a vector math node at 26' and 33' of the video, the Offset socket input is here to do the job.

Yamendo

Glad to hear you're working in resolve! Escape the clutches of Adobe!

Peter Mackey

Thanks for the reply. I didn't realise there was an OCIO plugin for Resolve to get filmic. I'm using a colour managed workflow in Resolve. I usually use Rec.2020 as an intermediate for grading video, but just realised setting it to Rec.709 seems to solve my colour shift problems with the EXRs.

Collin Cameron

It doesn’t actually take that long to render with Cycles X. I can usually render a frame in less than a minute on my old MacBook from 2012. That being said, the shaders in this video work in Eevee, which can still be realistic if dial in enough settings. One thing I like to do is focus on one element at a time while I’m making it using the / key, that way I don’t have to worry about previewing everything else while I’m not looking at it. I hope this helps!

Kash

It is just great that you do Geonodes now! the first tutorial that I could follow to the end :D 2 suggestions: 1-Your green keys are very feathery sometimes times now that you do Fusion there are way more complicated methods watch Simon Ubsdell channel keying tutorials he is a pro. 2- I think you can use a prop for the floor, right now it does not feel that the talent's foot is connected to the floor. if you use some sort of SciFi carpet you will solve the problem and worst case scenario if it doesn't work you can Roto it later.

chriskon

cool to see you do geometry nodes stuff! and looking forward to some videos on your resolve / fusion workflow

Gehrig Campbell-Dempsey

Love Fusion! Though price kind of makes it the defacto options if compared to Nuke haha. It has a LOT of extremely frustrating quirks, if you already know compositing though you'll be able to google around the issues. Shittiest part is definitely losing plugins.

IanHubert

OH! The Offset socket is basically just a vector math Add node? That makes sense! Thanks for that :D

Simon Salord

"The Offset socket is basically just a vector math Add node". Absolutely! :)

David Lisser

Thanks for tricking me into a geo-nodes tutorial. It’s been on my ‘to learn’ list for ages. I’ve watched a couple of tutorials and found similarly to yourself that often nodes are added without telling me why I needed it. Would love more of this, and also excited about a fusion tutorial too

Brian Luis

Hi Ian! So I was playing around with the transparency shader to make on object (pretty complex geometry) disappear using a mask as the factor. It worked great for some parts but I ended with these black artifacts that weren't transparent. I tried bumping up everything in light paths but it never full went away. Any idea how to fix it?

NickTricc

i am SO exited that you are mentioning resolve! Im looking forward to get more into using it.. I have the paid version, but i pretty much just use it to stich the pngs together..

Cypoe

yeah, that's not enough transparency bounces. you theoretically can put in any number up to infinity. But that's caused by alot of overlapping geo. One way is to bool, or rather mask the area that should vanish. Sadly in Blender you cant write Shader Output to UVs or onto Vertex Group, but if you control the shader using a Shape like a sphere, you can use a Proximity Modifier to write it into a vertex group and then Mask it by that VertexGroup. In the shader, the Object Info Node you most likely already derive the mask from takes in an Object as Input, select it. and anime the object rather than the mask inside the shader. voila.

Brian Luis

Wow, thank you for the response! I had a feeling I was going to have to use an object mask, I was using a video file that has a cool effect along the edge. I think if I use the two in conjunction I should be able to get the exact look I need. Thanks for the information definitely going to use it!

Anonymous

you can also make point cloud effect with this. thank you for tutorial! this is really exciting!

minju kim

HOW can I export this with transparents background? I want to put holograms on my other video.

Chris

Hi Ian! apologies if this has been asked/answered but been having trouble finding a solution. Do you know of a way to bake animations created in geo nodes? I've used realize instances to apply the geo node but as such lose the animation

Ian

In regards to ~28 minutes, the "average" of a noise texture is .5, if you use a math node to subtract .5 from the node path before the multiply it will instead be centered around the starting point.
