we're going to cover today in from the node Trey it keeps track of position rotation skill and visibility and is most used as a basis to inherent from or as a parent node to contain a bunch more nodes the marker 3D the marker 3D node is exactly the same as the note 3D only it shows the axis of the nodes within the editor it can be useful to keep track of invisible notes or a point in space visual instance 3D this note is not used Standalone but it's a basis for all visible notes to inherent from so everything that you can see in your scene it's based on a visual instance 3D it keeps track of what visual layer the node is on and it's bounding box so basically the space in which the visual is contained the geometry instance 3D just like the visual instance 3D this node is not used Standalone but it's a basis for all geometry based nodes AKA models it keeps track of lighting Shadow and LOD settings and it has a very useful material override property which can be used to easily apply custom material across all material Slots of a model the mesh instance 3D this node takes mesh data and combined with the two previous notes instantiates that mesh it can be used with gados building meshes or you can import your own models it holds the model and all its materials the multi mesh instance 3D if you intend to instantiate a bunch of meshes like I'm talking more than a thousand in a close proximity this node allows you to do that with optimized GPU performance it has a built-in population tool which allows you to distribute the mesh upon another mesh this node definitely has a lot more to get into so I'll leave the link to the docs down below the label 3D the label 3D note is used used for displaying text in 3D that simple the most important property on this note is the Billboard flag which makes the text face the camera and the pixel size and font size properties this allows you to change the resolution of the text decal the decal node is used to project a texture onto geometry Deal's most famous use is in bullet holes on walls or sprays in games like Team Fortress 2 and Counterstrike the Sprite 3D and animated Sprite 3D Sprite 3D and animated Sprite 3DS are used for rendering 2D Sprites in 3D they differ from just drawing a texture on a basic plane because they have built-in features like a billboard property which makes the Sprite face the camera and animation properties that allow you to easily Implement 2D animation spreite sheets into 3D the world environment note this is one of the most useful notes in gdau the world environment note allows you to change the global lighting settings of your scene at various postprocessing effects like tone mapping ssao and depth F field for example and it allows you to set up effects like volumetric fog and Global illumination the fog volume note when volumetric fog is enabled in the world environment this note allows you to add volumes of fog to your scene GPU particles 3D this is the particle system of CAU it really deserves a video of its own because it has a lot of features and settings the most important thing to know are the emitting settings can be changed in the process material property where you need to create a new process material and the visual of the particle itself can be set up in the draw passes again there's way too much to cover here in this video but most of the properties are very straightforward so definitely just play around with it and see what you can make GPU particle attractors and GPU particle collisions these six nodes are used to manipulate particles in the GPU particle system node the Collision nodes are used as you would expect and they can be used to give the particles something to collide with and the attractors can be used to manipulate the flow of the particles by pushing or pulling them the light 3D note the light 3D note is one again one of those notes that cannot be used Standalone but instead serves as a basis for various different lights in gdau it contains properties like light strength color and size and Shadow settings these settings will be applied to the following different lights the omnidirectional light 3D this is the most basic type of light it shines from one point to all directions around it it contains two important properties its range which determines the distance the Light reaches and its attenuation which controls the fall off meaning how much the light dims over the distance that it travels the spot light 3D this light is very similar to the omnidirectional lights in the way that they both have a range and attenuation but as you can imagine the spotlight 3D has a specific angle in which it emits light giving the spotlight effect the directional light 3D this light is a little different it lights up the scene from one angle and has no range or fall off it's used to set up a Sun or a moon light in your scene and has a lot of properties for tweaking its shadow settings the most important properties are the fade start and the max distance these properties allow you to tweak how far away from the camera the Shadows are rendered CSG shapes CSG shapes are constructive solid geometry shapes are meant to be used in prototyping and allow you to easily combine and subtract 3D shapes using Boolean operations with the option to enable collisions they are great for quickly combining shapes and blocking out stages and Interiors they can be used Standalone or combined into new shapes using the CSG combiner node let's get into the physics the soft body 3D this is kind of a weird one the soft body 3D node inherit from the geometry node and converts the geometry to a soft body physic simulation if currently quite buggy so don't use it for gameplay elements but they are great for quick visuals like flags and cloth the Collision object 3D this is another note that cannot be used Standalone but it serves as the basis for all 3D notes that collide with other objects the most important properties are its Collision mask and layer these layers allow you to specify what objects can collide with it and what objects it can collide with these may sound like the same thing but this is actually a very important distinction for example you could have a door that triggers a cut scene you would want your enemy and your players to collide with the door so they can move past it but you would only want the door to collide with the player to trigger the cut scene upon that Collision the physics body 3D again a note that does nothing on its own but serves as a basics for all physics bodies it contains some properties for locking certain movement or rotation axis of the physics body the following notes we're about to cover are different types of physics bodies all these physics bodies will need a collision shape to work the Collision shape defines the shape of physics bodies and Gau comes with a lot of default shapes like boxes cap and squares but of course you can import or create your own shapes a static body 3D a static body 3D note is a physics body that stays in one place meaning it cannot be pushed around or dragged down by gravity it is used for things like walls and floors and if the static body is moved for example by code it is in a physic sense teleported to the new location so it won't push balls up or move things to the side when it's moved you can however do that with a animatable body 3D this is a static physics body in the way that it cannot be pushed or pulled pull down with gravity but it does have the ability to push or pull other objects so when you move this within an animation or within code it will apply the appropriate effects to the physics bodies in its way the rigid body 3D this is the physics body that is used for almost all physics objects not controlled by the player so falling boxes flying arrows you name it it is pulled down by gravity and can collide with other physics bodies and it has properties for defining its mass bounciness and friction the character body 3D character body 3DS are types of physics body that can be controlled by the player they contain a lot of built-in features to make movement easy to control with code and gdau comes with a beautiful template that demonstrates these features the area 3D Noe this note was a little confusing to me at first but the area 3D node acts as two things one a detection field it detects when Collision objects enter it and leave it so it can be used for a trigger area or a Teleport area and two it can be used to define an area with its own physics and audio settings you can change things like gravity wind and the audio channel that the sound is going through this allows you to create areas like underwater areas or zero gravity areas in your game all right we've gone through quite a lot of notes today uh there's still some Physics notes I left out and a couple of visual notes using probes and reflection mapping we'll definitely get to those at the end of this series I'm going to combine all these videos into one long video will take about two hours I think and then you can have one giant video of just going through every single note within G do so yeah if you want to see that video or my other content I do projects and tutorial videos consider a subscription bye
