REFLECTIONS in Unity

[@Great.Milenko]

some stuff i've learned over the years about material properties. metalness or metallic, should always be used as a boolean if you are trying to get realistic materials. in real life a material is either entirely metallic or entirely diffuse. (as in metallic set to zero) metallic materials do not allow light to enter the surface, this is the defining property of metals, diffuse materials allow light to enter the surface and scatter when exiting, this is used for effectively ALL materials in reality that aren't made from metal. if it were possible to create a slider for realistic metallness at one end would be metal, at the other end would be a completely translucent material like a ping pong ball. smoothness (also known as roughness) refers to microdisplacements, this is the amount of variation in the normal of the surface, in shaders this is on a microscopic level so effectively gives progressively less blurry reflections, a smooth surface reflects light at the angle of incidence of the light ray leading to perfect mirror like reflections, only metals, glass and mirrors have perfectly smooth reflections, ALL other surfaces have some kind of roughness.... you could think of smoothness/roughness as a microscopic bump or normal map that has insane resolution no matter how zoomed in you are. normal mapping refers to a technique which replaced bump maps, although bump maps are sometimes still used and can still give effective results. a normal map will effectively fake a change in angle (or more accurately, the normal) on the surface, this allows you to add detail at very little performance impact, but as stated, doesn't actually create geometry, so can look bad if used for large details. a bumpmap is a simple greyscale image which is used to similar effect. a displacement map is used to actually modify the positions of the verts to create legitimate geometry which can silhouette nicely and can look amazing, although this requires a huge amount of verts to be effective, often a large amount of verts are created by the rendered with tessellation. parallax occlusion maps are similar to bump mapping, however the shader can actually cast occluding shadows onto its own geometry for a much more effective result. this technique can also be used to occlude the "virtual geometry" created by this map. meaning for example, a cobblestone street, when viewed at an angle will occlude parts of the material that would be occluded in reality. bump mapping and normal mapping can look bad in this scenario. a parallax occlusion map can look almost as good as a tessellated displacement map, and only use a tithe of the performance. although again, since no real geometry is made, it can look odd when seen in silhouette or when meshes are intersecting nearby. albedo refers to the wavelength of light reflected (or the proportion of which wavelength is reflected) an albedo map is NOT a diffuse map, a diffuse map usually contains some basic light information whereas an albedo map CAN be used to store light information like shading but USUALLY in modern games is used to store ONLY the colour information, lighting is usually done in real time these days so it usually removes the need to bake lighting into textures. lightmaps are usually used to save performance when a static scene or object needs to be lit without needing to use dynamic lighting for everything, this isn't a requirement anymore but its still super useful for increasing performance. lightmaps take the place of baked lighting in diffuse maps and are usually multiplied with the albedo map. they allow greatly detailed lighting without needing to update anything. allowing scenes to look amazing with effectively zero performance impact. emission maps tell the material which areas should glow and what colour they should glow. environment maps are a cheap alternative to realtime reflections, a HDRi can be used as an environment map, and indeed used to be the only way to get texture based reflections without needing to use shader based realtime reflections like screen space reflections... a light probe is another application of this same method, a light probe will generate environment maps when baked, instead of the old method (which can still be useful) of creating an image and using it throughout the area of the level it matches with. in fact the older method of creating a reflection map can be incredibly performant when used on things where accuracy is less important, like a characters eyes. interestingly the only difference between an environment map and an emission map is that the environment map is tracked differently and follows camera / worldspace to create the illusion of reflections. i know this seems ranty but i kinda had fun writing it, hope this sheds some light on some of those parameters.

When you enable screen space reflection you should select the reflection probe and disable it or delete it as it is still affecting your reflections. In an environment where the skybox is visible in your reflections, you can really see this. the way it appears unity handles reflections is; first, they draw the skybox onto the reflective objects, then they draw the reflections from the reflection probe and last they draw the screen space reflections. Because of this, if you have both a reflection probe and screen space reflections, you will notice the sky in your reflections having items from your reflection probes. and even when you don't have sky visible in your reflections, if you have the reflection probe set to update every frame, it is still doing that in the background and can affect performance. Like so people see.

Nice video! Can you please make a tutorial on animated textures/materials (a TV for example)? That'd be neat!

[@Bossasin]

Please!

[@personthehuman1277]

just make a render texture that watches an animation for the tv part, or use a video player component.

[@dmitryburlakov6920]

What about there's no screen space reflections close to the camera edges (easy to notice at 12:13)? How can we say to the camera to render bit more screen space for reflections, keeping field of view for player?

[@swipyduck]

Damn that was useful! Can't believe how just a simple post processing effect can do that much difference haha I'm downloading this right now !

[@irtezarahman5370]

Love you man. The best teacher

[@jackd8933]

The video doesn’t talk about box projection, which is incredibly useful for indoor environments like the scene in the tutorial. The default projection mode for the cubemaps assumes that everything is an infinite distance away. This is ideal for skyboxes and outdoor environments but not for indoor environments, because then the reflections are only appear to be lined up at the location of the reflection probe. Box projection projects the cubemap to the bounding volume of the reflection probe. This way the perspective of the reflection can adjust to the position of the player. When using box projection you will probably want to remove all objects from the reflection probe that are not a part of the wall, floor or ceiling (otherwise they will come out projected flat, since the cubemap is ultimately just a 2D image with no depth). Ultimately cubemaps and reflection probes aren’t a perfect reflection solution like ray-tracing, and they have severe limitations where screen space reflections might be more suitable, but they are incredibly performant when baked.

[@asgersrensen9303]

Best tut so far. Keep them coming :)

[@dylanhansen69]

Brackeys you should make a tutorial on making spherical terrain, like with Kerbal Space Program, because I want to build an exploration game somewhat like it and it all revolves around make spherical planets with terrain, specifically randomly generated terrain for ran planets.

Thanks bro for this inspiration! Best Hamzah Walled City Infotech

[@Das_Jonny]

Pretty interesting! I wonder if there is a way to set the settings to something like rendering the static object OnAwake but the dynamic objects in realtime. If there is a way to do this it might be a way to get both, best performance and best reflection.

[@ethanviolet1]

Brackeys could you do a video on making “real FPS controller” which means you see the arms and legs and your view shakes when you walk! I love your videos and I really want to see this. I have attempted doing this and it didn’t work the way I did it. I’m sure this is very useful to a lot of people too!

[@AJ-nm5fx]

Look into 3rd person camera controller on Unity asset store. Provides the options you seek :) Happy developing!

[@EricStOnge-yz9tr]

I thought of a solution for this, Maybe you could go in blender and make some walking and running animations and when you code in your movements, connect your animations to the same key

[@JugglingBlog]

Just get UFPS from the store. If you want to do it yourself, get a character and remove the head (or assign a material specifically to the head and cut it out). Bind the camera to the head bone via springs and you can get some nice camera shake that's customizable. This however is pretty basic and you'll need to do a lot of stuff to get a nice result, so I'd recommend just getting ufps unless you're doing this to learn how it works.

[@MusicandGame23]

i want ask a question about Post Processing Stack is: I'm in progress make graphics options but i wonder thinking it's how can post processing stack will connect with graphics options

Messing around with reflections I've noticed it's difficult to do this with transparent materials (For instance I'm trying to do reflections on transparent crystals) Do you think you could go into how to do that sometime?

Could you have multiple shiny things reflecting each other? Eg.. 3 or 4 reflective balls?

Could you please do tutorial on weapon switching with 2 or 3 weapons and some simple weapon switching animations. I’m sure this is very useful to a lot of people too.

[@MatheusLB2009]

Do a tutorial for ragdolls, that'd be awesome

[@lethn2929]

Ragdolls are easy, just look up character joints, ragdolls are just a bunch of character joints put together in the shape of a human, you'll just need to experiment to get it right.

[@jadonut249]

Can you do a tutorial on rain? I would really appreciate it! Thanks and keep up the great work :D

[@lethn2929]

Are you just talking about rain particle effects? Use particle collision if you want to do something with that and then have a little splash particle effect occurring when your particles collide with a surface.

[@Definitely_a_Fox]

Pretty sure there are some good tutorials on KZbin for that already...

[@СергейНаврожин]

Sup Brackeys. Wanted to ask your opinion on MVVM implementation in Unity. For example, using reactive extensions like UniRx. I am currently working on such a system, it involves a context provider, a scriptable object representing the Model, and an additional VM script attached to the default Unity UI components to handle the data binding automagically. The issue I am still having, is that if it's anything requiring data validation and transitions (popups, windows, lists of data, like levels in level selection screen), then another custom script is a must, that pretty much acts as a Presenter in the default MVP approach that Unity asks us to use by default. Could there be another way to handle that? I've seen people creating animation controllers to handle windows and popus - is that a good enough way? Did you use data binding yourself? Can you elaborate on the topic? Thanks.

10:58 It is sad, that still after so much time in development, Unity hasn't fixed the white artifacts around the edges of objects, that cause them to flicker (look at left and right part of the screen, where horizontal lines are flickering, also on the wall right behind the upper part of the ball). Even with the temporal antialiasing the problem remains. The same stuff can be seen in Escape the Tarkov, for example, where objects are "outlined" by white 1px border. P.S. Yeah, I know, there's assets that fix that, like the one in /watch?v=VWRfLhOY2AA , but I mean shouldn't be this be in engine for free?

[@sinviper4248]

I've got a problem. I added a object in to unity but couldn't move around it (get a 360 view) I was not in game mode either. It only let me go forward and backwards. I tried awsd and arrow keys. I also couldn't move around by using the cursor by clicking on the screen and moving my mouse around. if it helps im using a HP notebook for my project. ok thx :)

How to apply this to flat surfaces? It looks like this technology is made for this demo with the spheres only. The problem is that this is done using "virtual" camera inside the reflective object. But if my object is a cube the reflection does not look real at all.
