The production value and quality of your videos is outstanding. You deserve any success that may come your way.

I can't thank you enough! i was dreaming of how to make a render mask for effects like glow or lens distortion. i leaned more in the first 3 minutes than i could've hoped. keep up the excellent work!

This is really awesome. It almost works for a perspective cam too.

Again, very cool stuff. Thanks for your wonderful tutorials helping us beginners learn the ropes.

Really good tutorial with many clear explanations. I love it. I think that there is something to do with this principle - a good puzzle game. Thank you Seb ++

Infinitely useful tutorial. Thanks!

Amazing work as always!

It's very cool!Hope you publish more tutorial like this!

Nice! I'm going to try and make a version where what was previously in your fov fades slowly, like a memory.

Exactly what I was looking for. Thank ya!

Thanks @Sebastian for this tutorial serie about FOV. However, i can't get the stencil mask to work on my perspective camera (but it works very well in orthographic mode). What can i do to make it working in perspective mode ?

TripleA. Amazing As Always!

Thank you so much for this series! A couple of questions: 1) If you were to implement the same mechanic now (7 years later), what would you change in your approach? Have you learned some better ways to do it or is this one as basic as it gets? 2) Is this approach good for 2d games? It feels like creating 3d meshes for 2d space is excessive

Hats off man! Beautiful!

hey sebastian! do you know an easy way to implement something like a stencil falloff? like a view range that slowly fades out?

Hello, I've been wondering on will you be continuing on the "Creating a 2D Platformer" -series?

Hi! Awesome video! It helped me out alot. I have one pretty urgent question though - the fieldvisualization viewfinder I made according to this tutorial can't seem to see cast shadows. Do you have any idea what might be the problem?

Great tutorial as always! Followed it all the way through perfectly. Just a question if you happen to know. I tried an approach of duplicating the ground and having a standard material on the version that I want to see in the background, but for me that material has shadows of different lengths on it than are being projected onto my shader material when I make those parts visible in the field of view. Any thoughts on why?

Hey Sebastian, i'm currently working on a little game using your technique to create long shadows. Is it somehow possible (maybe with a shader?) to soften the edge at the end of the field of view circle so that it fades out like a shadow?

Thank you for your work. The video and the resource are all perfect. I want to ask a question. Can I use it with sprite renderer?

Firstly, I love your videos and have learned so much about Unity, coding, math applied to games and more. Secondly, I have a question regarding the shading effect when the camera is tilted. Is there some kind of easy way to make it work even tho the camera is tilted a bit? Because the shader effect gets really weird if the camera is not directly on top of the scene. Thanks so much for your videos, it helps a lot!

Hmmm. Is it possible to make objects using the StencilObject shader only cast their shadows within the mask?

These are amazing thank you so much

As a question, wouldn't it be better to scale the View Visualization object so that if you are doing a 360 degree area it shows the color behind as well as in front?

This is so cool!

would be cool if you could still see the background with a reduced visibility

Is there a way to modify this shader so that instead of everything not in view being black it is simply darker (ie take the normal color for that pixel and multiply it by RGB(0.25f, 0.25f, 0.25f)?

could you maybe do a series on how to make a ray tracer after this i would really love that.

This is working fine with 3D scene too, but the hidden objects have visible shadow :/ Any solution without set off shadow on the gameobject renderer? (I like to hide only the object, without black fog...)

Any ideas on how to convert this to URP/Shader Graph?

If you are using URP and the masking effect isn't happening, or your stencil shaders are giving a parse error claiming there is an unexptect "}", you can fix it by creating a new URP shader graph (if this is for the stencil object shader, set up sprite color & alpha outputs from _MainTex inside the shader graph editor, so that the resulting material can get the color of your main texture), click on "View Generated Shader" in the inspector, copy the generated codes from the shader graph to your .shade file, then make the edits in this video (add the stencil pass in the subshader before all other passes). As long as both of your shaders are URP, things should work properly.

Thank you so much Sebastian, you have no idea of how much useful has being your tutorials, do you know how to implement this in a 3d enviroment? do you think this would be expensive?(i say it for the raycasting)

Does this work on 2D too?

Thank you very much for this :3

Hi, this is really cool solution.. But I am still wondering, how to force viewMeshFilter to copy the terrain by its normal. If the terrain is not only flat surface. Or it would be nice, to detect height from ground during rendering the view angle..

I got something working in 2D The ` marks are not to be included and designates code between them: - I used the "unlit shader" instead of "surface shader". not sure if that part matters. Make the two shaders that Lague makes in the youtube tutorial. - Change the tags `"RenderType"="Transparent"` and `"Queue"="Transparent"` (and Transparent-100 for the mask). Below the tags add `Cull Off` line and `ZWrite Off` line. Do this for all 3 shaders total we will make. - Make a 3rd shader (I used unlit) and do the same changes as in the last step. Add a color property (check out Ronja's tutorial on properties www.ronja-tutorials.com/2018/03/22/properties.html). This involves a line in Properties block `_Color("Color", Color) = (0, 0, 0, 1)`, a line below pragma's but outside of structs/functions `fixed4 _Color;`, a line in the appdata struct `fixed4 color : COLOR;`, a line in v2f vert function `o.color = v.color;`, and a line in the frag function `col *= _Color;`. - Also add a blend to the fog shader. add below tags `Blend SrcAlpha OneMinusSrcAlpha`. - Add a stencil block to your fog shader, but it's going to be opposite of your object shader. So it's: Stencil { Ref 1 Comp NotEqual } - Make a material for each of the shaders (3 materials, one for mask shader, one for object shader, and one for fog shader). For the fog material, the color is currently white because of the (0, 0, 0, 1) part from last step. Change it to black and change the alpha via inspector window. The blend line will use this alpha so play around with this value. - Make a sprite that covers your level. Make sure everything on the same z-level (probabably 0). This will be your fog, so change the material to your fog material. - Change your view visualization cone material to your mask material, and change any objects you want to not render outside the cone to your object material. I hope I got everything I did in this comment. The fog is an optional difference I made, because I would like certain objects to just be darkened instead of not rendered at all, but you could leave that part out if you want it more like Lague's tutorial (and just make everything object shader so it won't be rendered when outside of view cone).

Maybe I figured it out. You build a mesh of the visualisation and give it a transparent white-ish material. Then, place another mesh over all of the map. Make it have a transparent dark material. The places that are not seen in the field of view are darker than the where there is a view mesh, since the mesh's white-ish material cancels out the darkness. It's a hacky way of doing it, and I'm sure there's a way better way, but it's what I've got so far.

@distrologic2925

7 жыл бұрын

you would probably need something else than a stencil shader, since a stancil shader is mostly only used to store "On/Off" vaules. a depth shader could store float values, which you could use as a transparency value. I have no idea if or how this works in unity however.

I'm currently trying to find a different solution, but right now I have this (I'm using a 2D scene, this might not work in 3D): 1) Duplicate the original object, darken the surface of the duplicated one, and move the original object above the duplicated one. 2) Apply the Stencil Object Shader to the original object. When the original object is hidden, the copy below it be be revealed, giving the illusion of transparency.

You are amazing
