3D in Resolve & Fusion - What’s Really Possible?

welcome to a short roundup about the 3d capabilities of DaVinci Resolve and Fusion today I want to look at what our typical use case scenarios where you use fusion what are the primary strengths for 3d stuff in fusion and where are the limitations of the 3d rendering and the 3d applications that you can do in the Vinci result fusion or Fusion studio recently I have done quite a lot of tutorials about individual 3d topics and even some use cases and the question comes up again and again how far can you actually go just inside resolve or just inside fusion does it actually replace software like Maya or blender or is it more like some assisting features do I even need to learn them can I just stay in 2d if I have my 3d applications or if I work with other people who use 3d applications so today I really want to place the software a bit explain what the 3d environment is primarily targeted at and how it can help your workflow so today not a step-by-step tutorial instead an overview discussion so lean back and enjoy and let's dive in the first thing that may come to mind when I'm talking about the 3d environment in fusion are like 3d texts and motion graphics and motion graphics with particles and you see here a few examples of recent tutorials I have released but this is not actually my main thing what I'm thinking about and my main focus at the moment I want to talk more about compositing in 3d and they're the first example I think of our 3d set extensions now set extensions can be simple if the camera is locked off you can actually do it completely in 2d or even when you have a moving camera sometimes it's enough to just track individual points and with a little bit of trickery you can fake the perspective even in 2d however if you truly have rotating moving camera and you need the perspective changes the correct parallax movement etc then you should work in 3d in this case you are not necessarily building like highly complex 3d scenes potentially you're just adding some images on an image plane maybe you're doing a little bit of projection here in this example I am adding an image of a house but you could also think of adding for example a green-screen actor on a simple cart like in Trudi on a 2d image plane you place that actor in the 3d environment so that if there's a little bit of distance and the camera films that act or films that card of hims the house in this example you still get an accurate 3d feeling from from the final rendering the second scenario I'm thinking about are these pen and tile kind of video creations they use photographs as a video background or as video source in the first place so you can sometimes stitch together photographs or you can use cyclorama k-- photographs as a new background or as a full environment in which you then can animate the camera you can drive this even further by using projections and by using like foreground background projections to project photographic elements or matte paintings on different simple geometries and then film them in 3d in order to come up with the three-dimensional film environments sometimes this is called 2.5 D because you still work with two-dimensional images and you just place them onto cards or card projection parallax projection you find different names around this but the idea is always that you have two dimensional elements which you can somehow stake in a 3d environment and then film them with a 3d camera for a convincing 3d effect you could take this a bit further by taking 360 photographs or hgri backgrounds and use them composite them together with video footage or you could go all the way to VR footage and can do stitching inside of fusion you can stitch together BR footage and then either render it out as 360 output or you could work within the VR environment and then again create a new camera track for a 2d output finally you can import full 3d models into Fusion and I have done that in a recent tutorial back kind of try to do everything in Fusion except for the modeling and this is possible however perhaps the more important task is that you can use the geometry for secondary compositing tasks so if you are working in blender or my own other 3d software perhaps you are rendering out your 3d objects directly from that software but you might want to work in fusion in order to create shadows or you need certain masks or so and in some cases it's actually easier to work in 3d than in 2d and to create for example shadows directly from 3d or to create masks from 3d here this example I rendered completely from Fusion however even if the spaceship was coming from another application even if you were rendering it from another application you might still for example create the shadows inside of fusion there are certain 3d tasks which can be performed quickly and fusion and almost interactively and sometimes it's just faster especially if it closely relates to your 2d compositing tasks it might just be faster to do it directly in fusion instead of going to a four blowing 3d rendering application so how much can you actually do in fusion when it comes to modeling lighting and rendering and and what should you not try in fusion so first of all let's talk about geometry so when I'm creating geometry in fusion I have like simple geometric objects which I can create and combine and modify so I have my cubes and spheres and cylinders and pyramids and that kind of stuff and I do have some options to modify them for example I can bend them or I can replicate them and so on what you cannot do is like directly go into the 3d object and like extrude vertices or edges and directly model or even paint like you know what you can do in 3d modeling and applications or in ZBrush or that kind of stuff so you're not directly crafting and sculpting you just laying out some basic shapes and you can use these then for for for projection you can modify a bit also image driven so you can for example if you have a Z channel for an image you can use that or you can use grayscale images to extrude surfaces and you can come up with some interesting shapes there but it's all the kind of procedural stuff that you are doing you would rarely think about building a sophisticated model from scratch you can import 3d objects as I mentioned before from other applications so you can import FBX measures or obj meshes so from the major 3d applications you can import the meshes you can also import the textures and you have the illumination models to accurately render the diffuse and specular color you can get the shadows from Lighting's that you can set up inside of fusion so in this way it's pretty sophisticated also bump maps can be added on normal Maps so the lighting and shadow can be replicated inside fusion so you could use it directly and to render these objects and in some simple cases that may very well work and might save you some time compared to going back to a full 3d application or it might make it accessible to you if you are not familiar with those applications and you're just using fusion however there are definitely limitations when it comes to the rendering so one thing which is missing is any form of global illumination and any form of interactive lighting so you are not getting you are getting like direct lights you are getting specularity and shadows but you're not getting bounce light you're not getting subsurface scattering you are not getting ambient occlusion you are getting regular shadows but ambient occlusion you can create as a 2d post effect but you're not getting it natively out of the rendering also image based lighting is not supported so that sometimes a very nice trick in other applications where you can use an HDR IMAP to immediately light an image but this is not supported out of the box now there are always certain workarounds and certain tricks how you can make this how you can simulate this or you can make this somehow work but it is not a native rendering capability of the fusion renderer so in these cases really the true 3d renders are much much more sophisticated also there's a long list of really advanced rendering capabilities that advanced rendering solutions have like rendering cow sticks for example you don't think about that kind of stuff in fusion to put a bottom line under all of this Fusion is strongest the closer you are to the 2d pipeline so if you are working with footage with photographs matte paintings VR footage etc and you need the third dimension for projections for the correct parallax for the correct integration then fusion really shines in addition you have all these little tasks where the 3d environment can help your 2d compositing where you can maybe use the 3d models and directly work with them interactively to create some shadow or to help your lighting and and create some additional passes that you may not have gotten from the 3d side in some cases you might even be able to do the complete 3d work and whew like use a model or use a logo or create something directly in fusion if it's a small task and you don't have like the most sophisticated rendering requirements you can do this kind of small tasks directly inside of fusion I hope this helped with the overall expectations of what you can do and cannot ensure - and gives a bit of a stage I have done a lot of tutorials recently about fusion so feel free to check them out on my channel and on my website you also find a free course there that focuses more on 2d but if you need the introduction go ahead otherwise a like and subscribe is always appreciated my name is bound thanks for watching [Music] you
