I will !

Je ne m'en déferai jamais de celui-là ;) Merci beaucoup, ça me touche !

I didn't use DistanceAtten indeed About the normal map, you should add a texture for the normal map, then multiply the output of the texture sample 2D node with the normal vector, and use the result instead of just the normal vector for the dot product with the light Hope that makes sense

Patience mate! I'm a bit overwhelmed these last months but I will definitely make the sequel in the future

Only great questions here! About the layers, you can use materials that have stencil behaviours for the objects in the cube without having to modify their layer indeed. The drawback of this method is that you have to create a custom shader for these objects so that you can customise their stencil behaviour. You wouldn't be able to use any material for these objects, whereas you can with the layer method. About the mask shader: yes, Comp Never / Fail Replace is a great method for making an invisible mask. However, it won't draw at all, so it won't write into the depth buffer. It could be annoying for some edge cases, but for I tend to prefer that approach too. You don't need ZWrite Off or Blend Zero One with that technique, I find that quite elegant. About your last question, I partially answered it before but just to clarify: if a pixel fails the stencil test, it is not rendered. If it is not rendered, it cannot write into the depth buffer. Hope that helps!

@@pixtrick Amazing! Thank you

If you want to see through the hole, yes it could be useful. However, most games use decals for that, which is basically slapping a bullet impact texture on a wall. Still, I would be curious to see that! That's kind of a good idea :)

It is my pleasure!

This shader works only for opaque rendering, it does not handle the transparency unfortunately ... It would be something to dig in if I would remake this shader

@@pixtrick i know that but if is possible to make the shadow to have lighter color's and add objects that only have shadow I'm probably able to make the system i wand to make.

That's good news!

Hey ! Thanks ! Yes it's my bad actually, I should do an updated version of this tutorial since it's quite old now. It's due to the order in the operations, I posted a fix last week on the GitHub repository if you want to take a look !

Not sure, but all the tests I've made so far point to the fact it is not

Hey ! You can check the pinned comment, maybe it would solve your problem

@@pixtrick I found the problem I was not using URP T_T Anyways awesome video and I appreciate the response!

@@jarvinvruizeeslao happens x)

Don't hesitate to message me on discord if you need anything

Hey ! Have you also imported the .hlsl file that was provided in the files ?

​@@pixtrick Yea I did

Can you contact me on discord? It would be easier to understand your issue

I'm still doing it today 😭

You're flattering me x)

Thanks a lot ! :D

Thanks a lot !

Thanks ! I'll try to post it as soon as possible

Absolutely, that was just an example, it's totally up to you to improve this ;) In this case what you would do instead is disabling the collision between the 2 colliders basically

What unity version are you using ?

2022.3.17f1@@pixtrick

You have to make sure that the depth priming is off, and I'm not entirely sure but I think setting the rendering path to forward can help as well

@@pixtrick yes it is disabled and the rendering path to forward, I tried different depth texture modes as well. I'll try to isolate the problem by making a new project and make some test and I'll come back to you.

@@TheGameLecturer all right ! By the way you can message me on discord if you prefer

Hey, I'm not very sure about that, you should try ! In any case, if the render features are not available, you can still use the stencil buffer through custom shaders

It is indeed possible, but you won't have access to the render features. Basically, the URP allows a per-layer rendering with its render features (so you don't have to worry about the materials of each object of the layer), whereas the built-in RP don't, so you'll have to write custom shaders to get the same result, it's a bit harder but 100% doable in my opinion.

@@pixtrick thanks for the response! I finally succeeded! I think the hardest part was that i used Amplify and its stencil buffer parameters were some time buggy 😅 But you're explanation was really great and help me find the way!!

Unfortunately no, shader graph doesn't support the stencil buffer

Hey ! You just have to use a render feature then. Basically, instead of using a shader for the mask material, you just have to create a render feature with a Never stencil comparison operation, so that it won't show on screen. You can use any material you want for that mask then since it won't show on screen at all. EDIT : I forgot to mention that after doing that, you'll have to use the Fail operation instead of the Pass operation, because the comparison operation will always be false, so that the Pass operation will never trigger.

Hmm, yeah, I just can't seem to figure it out. I was trying to make something for the Apple Vision Pro but you can't use normal shaders, you can only use shader graph (or other node based shading methods), because they use MaterialX which requires node based shading. Thanks for your help though! Appreciate you taking the time to respond.@@pixtrick

@@helikaon00 I struggled with the same thing and got it to work. I don't know if it will work for you or anyone else reading, but this is what I did: - Make sure that the culling mask dropdown menu of your main camera has both your walls layer and your occlusion object layer checked - Make sure the proper render pipeline asset (the one you have the stencil on) is set in the quality section of project settings - Make sure that in the "Filtering" section of the render pipeline asset inspector window, the Opaque Layer Mask dropdown has both your walls layer and your occlusion layer UNchecked - On the render feature for the walls, set Event to AfterRenderingOpaques, set the layer mask to your walls layer, enable Stencil and set its value to 1, and then go "Not Equal, Keep, Keep, Keep" for the next four dropdown menus, in that order from top to bottom. - On the render feature for the obscuring object, set Event to BeforeRenderingOpaques, set the layer mask to your obscuring object layer, enable Stencil and set its value to 1, and then go "Never, Keep, Replace, Keep" for the next four dropdown menus, in that order from top to bottom. Lastly, in case anyone wants this to only work when behind a wall, not in front, give your obscuring object a new script. Have it fire a raycast from itself to the main camera every frame. If the raycast is obstructed by any object in the wall layer, change it's scale to whatever size you want. Otherwise, change its scale to 0. I'm not a professional at this, I figured this out through trial and error. So if it doesn't work for you, I'm really sorry but I have no clue how to fix this. I just hate when people post "I figured it out" and don't say how, so hopefully this helps someone.

Decals are not compatible with the stencil buffer, or at least I haven't find a way to make them work together yet. We discussed about it on the discord server of the community but didn't find a solution ... Regarding SSAO, I'm not entirely sure why it doesn't work as intended ... It may be either the AfterRenderingOpaques event queue or simply because objects rendered through a render feature are not considered as "real" geometries

Thanks for the kind words ! :D

I'll try to make a video on that

Hi ! It's an inverted render culling, you can access this parameter in the material editor

Hey, thanks a lot ! I'm not sure to fully understand your request to be honest, is it about the floating text in the magic card? If that so, it's only a canvas in world space with appropriate dimensions

@@pixtrick nonono, I have an eyetracker device, I can know the user position and I want that the monitor screen act like that portal to make that card effect, It's so tricky. If you atatch the game camara to the user real position works but not that good that the card effect

It's hard to explain, also is similar to the 3d wallpaper efect, but that use the acelerometer, is not that real effect

@@ToniehGaming ok i think i'm slowly getting it. Is it like a parallax effect ?

@@pixtrick Not so much like a parallax, more like the monitor was a window and there were things through it. It looks the same as what the card effect looks like.

Hi ! I think that what you saw is also based on the stencil buffer, but perhaps the main difference here is the use of the URP which allows you to add stencil parameters on any rendered material. However, I agree it might be annoying to set up, so if you're only using hand-written shaders (shader graphs doesn't count), you can add these stencil behaviours way more easily. Does it answer your question? x)

@@pixtrick Thanks! Yes, that answers it:)

Hey there ! You just have to disable shadow casting in the mesh renderer

Okay, and if I want to cast just when it is enabled and then when it is masked, disable it ?@@pixtrick

@@ninocoillard6775 when you say enabled, do you mean when you can see through the door or do you have something that enables or disables the view through the door ?

I'll try !

Hello there ! What unity version do you use ?

@@pixtrick22.3.15f1. Also made that line fix you mentioned in the pinned comment

Hey! Thanks for the comment and the kind words I appreciate that! Now, about your question, I don't really think there's a real workaround for that, since the shadow caster pass uses the vertex data to draw shadows. Since the fake geometry created by the stencil buffer is not an actual geometry (I mean it is not some vertex data, it's just pixels on screen), the shadow caster pass cannot render there properly. Then, I don't really see any workaround for keeping the ground shadows while not rendering them into a hole. Now, if you really need your ground shadow (I assume it would be for like a platformer game or something), I would suggest not to use the stencil buffer unless you're really forced to. Use real geometries as much as you can. I think this is not (or maybe it is but it would be such a pain regarding performance) possible to draw shadows pixel by pixel, so that the shadows are not rendered into the hole but are rendered for the ground, but that is absolutely not reasonable. May I ask you what you are trying to achieve? Maybe there's a workaround in your situation and I would be glad to help :) Have a great day !

​@@pixtrickThanks so much for the reply :) I think, I figured out two possible solutions by now but either way it sucks a bit that this is so exhausting to do. Beware this will be a long text, thanks for letting me rubberduck a bit. It is in fact not a plattformer, rather an isometric adventure type of game. I am making this example up but the situation is basically like this. Imagine a hill and ground mesh with a meteor crater on top. The crater is the hole I would like to stencil out. I can not build this right into the mesh because it is procedurally placed. Inside the crater I have a plane which reads the depth texture to create some fog-ish dust. Issue 1: Shadows of the hill are drawn without the stencil cutout hence everything in the crater is shadowed. Turning of the shadows would mean no shadows in the surrounding area by the hill. Issue 2: the information in the depth texture is also wrong. This is a bit harder to explain and needed a bit of digging in the frame debugger and render pipeline. The Render objects feature only writes to the cameras color target. The color target contains a depth channel but it is only used when certain conditions are met. For example in the game view, if depth priming is disabled and nothing else forces a depth pre pass (like ssao in depthNormals mode). The scene view always uses a depth pre pass not matter what we do. When we remove the ground from the regular render loop and only render it through render objects it is completely removed from the depth pre pass because the render objects feature does not set that up and the mask definition that we have set excludes it from ALL main passes (except for shadows...). I wonder why this isn't done in the render feature but that I guess that this is the reason why the feature still says experimental. Unity didnt figure out a way to make it compatible with any possible srp renderer. This is an issue what the typical "hey draw the characters silhouette" tutorials don't have because they draw the character in the regular loop too. As for solutions, one option I can make work is not using stencils at all. Render everything in the main loop, set the queue for ground materials to 1990 and create a depth mask shader + material that overwrites the depth where it is rendered with infinitely far away. Then everything that is rendering afterwards renders as usual and even shadows are correct (because the shadow passes use the depth only passes of the shaders too). The other solution is to modify the render objects feature to also create a depth pre pass or inject the missing draw calls into the existing pass with the correct stencil renderblock set and render the stencil render objects feature extremely early (before pre passes). Second solution is more flexible / cleaner and actually allows using the stencil buffer fully but it is much more work. I am at the point where stuff renders in the depth pass but not with stencils yet. I guess my issue here is simply summarized with: Render Objects does not work with depth pre pass, stencil in render objects does not work with shadows in URP, but it could, unity just didn't finish it yet 😕.

Hmmm your thinking process might be good, but I think there's a much simpler solution for such a problem. Basically, your problem is : how to generate a hole in a procedurally generated terrain. To me, this is much simpler than having to deal with depth pre passes and everything, plus it would be much more cleaner. As I said before, you have to use real geometries as much as you can, and only use the stencil buffer when it's needed. To me, you shouldn't use the stencil buffer at all for this problem since the crater will not move in your scene (I mean I assume it won't move). I don't know how you generate your terrain and how it should look, but I think you should use techniques such as the wave function collapse that allows you to design "tiles" that you can put together in numerous ways. That way, you can keep a procedurally generated terrain and would only have to make a tile where there is the crater. If you still really want to use the stencil buffer, well don't xD I cannot really help since I think it would feel broken ether way. Still, it was extremely interesting to read your different solutions, but yeah to me you should change your approach to this problem. Hope that helps !

Thank you so much !
