Projected Decals

Hi,

We are working on a WebGL game which contained the asset pack 'Dynamic Decals' to project decals onto objects (https://assetstore.unity.com/packages/tools/utilities/dynamic-decals-76410) which worked perfectly in 2017.2 . Now we are trying to upgrade our game to 2018.2/2018.3b but the decals don't work anymore. Also the asset pack is no longer supported.

Therefore we tried other decal packs: 'Simple Decal System' and '3D Decals' but they don't work either.
Does anyone know if there is a functional asset pack available? Or are there other ways to project decals onto game objects since HDRP is not available for WebGL?

Thanks a lot!

 

Not sure if this is what your looking for but...

I modified the stuff I learned from this: https://www.patreon.com/posts/rendertexture-15961186

to do this:

Knew very little shader code before digging in to that, and had only used render textures a couple times before for camera stuff.

The performance is great, the game runs like butter on older mobile devices (if you turn the ads off). And runs fine in webGL. Shameless plug: check it out on armor games on oct 25th.

 

maybe same issue of this ( cann't write depth to rendertexture use GLES )

and thread

*No repro in: 2018.1.9

 

Thanks @itsDrew i will try that out @kou-yeung maybe it's the same issue, i will follow these threads

 

fixed issue( https://issuetracker.unity3d.com/is...ite-depth-to-depth-texture-on-android-devices ) at Unity 2018.3.0b6.

 

Thanks for the update! Do I have to change some specific settings? Otherwise my problem isn't the same

 

not have to change any specific settings.just update to 2018.3.0b6.
if have same problem.maybe not same issue...sorry for that

 

I don't know, I also use Dynamic Decals in a WebGL project and can't remember them being broken – and I went through most of the 2018.3 beta releases.



They work fine for me. Perhaps there's a problem somewhere else?

 

Did you try to build the game? I created a new blank project with just the Dynamic Decals package and built the demo scenes (Goos and Classic scene) for WebGL but the decals didn't work, they are invisible. Everythink but the decals seemed to be working properly. Maybe it's the build settings? Can you try to build your game and tell me if it's working?

Edit: In the editor and when in play mode the decals are working too, strange...

 

Hm, now that you mention it, I didn't try to build the game for a while and no – in the build, the decals are gone.
I remember that for an unrelated project and asset, I had to manually put some shaders in "Always Include Shaders" under graphics settings for it to work… but Dynamic Decals have a plenty of shaders and trying to include some of them which I believe I'm using (e.g. Projection/Metallic/Deffered) didn't help much.

In the browser console, it's spamming this warning:

[.WebGL-000001A7BC6E6950]RENDER WARNING: texture bound to texture unit 1 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering.​

even though I'm not sure if it's even related to this problem.

You could probably write to the author since even though the asset is very unfortunately deprecated, in the last post he wrote, he says he at least still intends to 'support' it.

Or maybe it's Unity's issue.
I'd say it's reasonable to believe that whatever works as expected both in Scene View and Playmode should probably work in builds as well.

 

@creative_nap – Hi, I've been wondering, did you eventually manage to solve this problem?

 

@Rallix no unfortunately not, tried many things but the problem does still exist. What I didn't do is to write the author for 'support'. Im sorry...

 

We are having this problem as well now with Dynamic Decals showing up in the 2018.3 editor, but not in builds. @creative_nap @Rallix still no luck I'm guessing? Have either of yall created a bug report yet? This issue exists on regular standalone windows builds as well.

 

@BurningToad I created a bug report only last week (so there's no reply yet), based on the fact that the same package used to work in a previous version of Unity, but doesn't work anymore (as Schubkraft suggested).

WebGL builds spam
"[.WebGL-…]RENDER WARNING: texture bound to texture unit 1 is not renderable. It maybe non-power-of-2 and have" incompatible texture filtering. "
in Google Chrome, and the same build opened in Edge:
"WEBGL11163: clear: Invalid framebuffer operation."
"[2x] WEBGL11163: drawElements: Invalid framebuffer operation."

However, a standalone PC build works fine for me. To report the bug, I made just a simple "cube on a plane" scene and slapped a ProjectedDecal component on it. Worked in the Editor, in the Standalone build but not in WebGL.

I'll let you know if I get a reply.

 

We also use Dynamic Decals (shame its been deprecated btw) in our WebGL projects - our latest
game https://www.miniclip.com/games/police-pursuit-2/en/#t-l-gs1-H is working just fine with it. The car shadow blobs as well as the lightspots (HD settings - first campaign mission) use Dynamic Decals.

I do always have to fiddle around with it to make it work though - and I do recall as well that before 2018 it wasn't as much of a hassle to get it to work.

Now for webgl I have to make sure the Shader Method (Window > Decals > Setting) is set to Mobile and you have to make sure depthnormals are being rendered for your active camera. If they are disabled you would have to force them on somewhere.

I am not sure if this is the proper setup or just a workaround for another issue - hope it helps though

 

@PieterAlbers Thank you so much for the tip! Yes, that's what did the trick for me – switching the shader method to Mobile and also making sure Force Forward option is selected.
I was already using the depth normals mode for my main camera before, so I'm not sure whether it impacted anything.

 

@Rallix No thanks
I still think it's a workaround since I can't recall doing this for some of our older games with Dynamic Decals built in 2017 or at least before 2018.2. Unfortunately I don't have a lot of spare time to get to the inner workings and see what is going on.

 

Has anyone got this working for 2018.3? I used it in 2017 and it works great,but not with 2018.3 + Also, I made my own system and when I get time I plan to see what I can do to get it working with my system .. with 2018 and 2019. because right now, we don't have anything..... Unless you use Unity new Rendering, which is still a ways away...for production work.... so if anyone, had got this working let me know. or plans to work with it still for new versions. Thanks!

 

Sure.
I think people in the official thread said there's no problem with functionality except for a few new warnings which you need to fix (mostly related to the new prefab system).
I personally tested PC/Windows on a small project, too; which worked all right. WebGL didn't work until I did what PieterAlbers proposed – now it's working fine for me.

If it doesn't work for you for some reason, you could try the same fix – change shaders to Mobile (even if you're not making the game for mobile) to see if it helps.
