How To Create Bill Board Shader Graph In Unity

Hello everyone, welcome back to the channel.
In this video I have tried to explain how we can create a bill board effect in unity's shader graph.
A billboard in Unity is the process of representing a two-dimensional sprite or mesh in a three-dimensional space. It typically involves forcing the sprite to rotate with the camera so that, just like in a 2D game, the camera is unable to view the sprite with any perspective.

its not working for me the Buildboard works but it makes the object in visible and I don't have alpha clip on it idk if it just I'm use hdrp or what. edit : ok i just found out yes it was the render pipeline I was using but idk how to get it to work in hdrp

[@iDigvijaysinhG]

Hi, well there are two position spaces, "World" and "Absolute world" while in URP they are treated as same, in HDRP "World" is treated as relative to camera and "Absolute world" the actual world space. So your mesh is not invisible it will be showing somewhere else. To fix it, you need to tweak "Transform" node where we are using "World" space, simply replace it with "Absolute world" Good luck

thanks it work now

@@iDigvijaysinhG Hi,Thank you very much for your solution😀, but I have a problem. I used Alpha Clipping which resulted in incorrect shading and a wrong result as the angle of the light changed. How can I solve this problem?

@@姜磊磊-w3s Hi, sorry for the late reply, for some reason I got the notification just now. Generally Billboards are used for far away objects so it's a good idea to keep them Unlit and make sure they also don't cast or receive shadows as well. For the lighting, override the albedo with a tint color that roughly matches the scene lighting.

Thanks. If anyone else have rotation issues, switch the Y and Z values after the split (R to X, G to Z, B to Y).

[@Mineboy15]

Thank you so much!!

[@CorleoBabar]

Almost exactly what I was looking for, but it worked like a charm anyway. For those wondering, you can make this a lit Sprite shader instead if you need to make a billboard sprite material, all the nodes in the graph are identical. Thanks!

[@purgebs101]

I followed this to the letter and it works, except that if I move my billboard object it moves away from it's pivot point. It happens whether the object is parented or moved by itself. How do you fix this....?

[@JanJulius]

I have the same issue.

[@iDigvijaysinhG]

Hey, I have tried to replicate the issue you have mentioned, but could not recreate it. I have tried with simple quad and custom mesh on Version 2022 LTS (For obvious reasons) and it works without issue. Are you by any chance using HDRP?

[@JanJulius]

@@iDigvijaysinhG I am using URP, also, I want to use it on a skinned mesh render but I don't know if your shader is sufficient for that anyways Idk if purgebs101 is having the same issue.

[@iDigvijaysinhG]

@@JanJulius Ok, It seems like that might be the issue, I am not 100% sure, need to check it and I will get back to you.

[@EmberlingYouTube]

Did you ever fix this? Having the same issue, using simple Sprites and this shader on my Material. I would much appreciate a solution!

[@tomokinryou1860]

It's worked!!Thank you

[@intensevideogame]

Is there any way to have it only rotate on a specific axis? I am trying to use it for a tree LOD, but It rotates on the x and z axis which I don't want.

[@iDigvijaysinhG]

It's definitely possible but it can't be done simply by tweaking this shader but I think this will guide you in the right direction www.reddit.com/r/Unity3D/s/29NUNqZgPl

[@gregorywheeler6610]

At least in Unity 2022 using URP, this doesn't seem to work at all. I've watched the video repeatedly to see if I flipped a World and Object position somewhere, but if that's the case I can't find it. The issue seems to be at the part where the Object Position is added, as that is where the preview colors no longer match with the video.

[@iDigvijaysinhG]

Hey, The video is made using Unity 2022.2 so I don't think the editor version is the issue. Could you upload a little screenshot and share it?

[@adrianmaj8656]

Thank you for your help! 😄

[@iDigvijaysinhG]

My pleasure 😊

[@tufanaydin6340]

Working good thanks

[@jameskwon8906]

hello. I applied the sprite and applied the shader above. It came out fine when it was a single object, but there was a problem where it didn't appear on the screen when I cloned the object that I had applied.

[@iDigvijaysinhG]

Hey James, I will get back to you as soon as I reach home. Meanwhile is there any chance that you are on HDRP?

[@iDigvijaysinhG]

Okay so I am unable to replicate the issue by duplicating the quad. So I need more information like the Unity version you are using, which render pipeline you are one and the version of render pipeline as well.

[@jameskwon8906]

@@iDigvijaysinhGI am using UNITY ENGINE URP.

[@jameskwon8906]

Thank you very much for your interest in my question.@@iDigvijaysinhG

[@iDigvijaysinhG]

No problem, but I still need the version information like which Unity editor you are using e.g. 2023.1.3f1, URP package you are using e.g. 17.0.2.

[@sorenmuller1974]

Works super, but how do I correct UV in order to show texture on it ?

[@iDigvijaysinhG]

Simply setting the texture to Albedo should work. Need more details of the problem you are facing.

[@DuckReaction]

Hey my billboard is displayed but it looks at the same direction of the camera. So it's invisible. How can invert rotation?

[@iDigvijaysinhG]

Why complicate ourselves by inverting direction, simply set material to display the back face.

[@borkyborkborked]

@@iDigvijaysinhG because the billboard will also turn in the opposite direction...

[@뽀루-r9r]

Great Thanks

[@bamfyjifu]

For those having issues, you might have tried it on a "plane" rather than a "quad" a plan is flat in the y axis so it appears invisible when the shader is applied. A quad does not.

Intro is too loud compare to the content.

[@iDigvijaysinhG]

Sorry about that, I was a noob content creator back then.
