Easy Decal - Decals everywhere

Don't mark them as static if you need to move them. When they are moved, then you need to re-bake the decal with LateBake() - maybe write a script that checks the position every frame and calls LateBake() if it has changed?

 

Hi nu-Asset.

Can i ask if it would have a good and really usefully use in a Graffiti Maker game where the player has a Spry-Can and must paint on walls? Something like the GTA-SA graffiti but more more deeper,

Thank you very much!

 

I'm not setting them as static, I bake them once they are spawned, what is static is my geometry.

 

Have they got colliders? Have you setup a StaticMeshProxy?

 

Hi,
I have problems with batching decals. In attachment you can see that batching is broken because of "different light probes", but from script I have turned off reflectionProbeUsage and lightProbeUsage from DecalRenderer propery.

Can you help me with this problem and comfirm that batching is working?

 

I just purchased Easy Decal. After I import the asset and open easy_decal_doc.pdf, I found the verion in the document is 1.6.4. But the latest version is 1.6.8. How could I confirm I have the latest version (1.6.8)?

 

Open up the location of your ch.sycoforge.Decal.dll file and look at the properties. On Windows (not sure about OSX, sorry ). Then go to the details tab - should show up under product/file version.

 

Yes, they have colliders that's why I included the videos showing the problem.

Is whats a static mesh proxy?

 

It references all the static colliderless objects. However, since they have colliders this won't fix the issue

 

Just place the decal onto the object you want to decorate in the editor and then either bake it or convert it to a mesh.

 

This is possible of course. Depending on the use case you choose between deferred and mesh decals.

 

I'm very sorry for the late reply. For some reasons, we dont receive any notification for the main thread. Your private message notified me.

The lookup searches for geometry data started on the level of the first hit collider. But in your case, the location of the combined mesh within the hierarchy changes (probably to the scene root) and the projector can not find them anymore.

I'll double check the deferred issue.

 

When nothing significant has been changed that immediately affects the user interaction or UI the docs get submitted with no changes. This just means that the last updates were affecting just the core framework.

 

This should only be the case when working with deferred decals as they have disabled the auto batching functionality of Unity. (The auto batch will corrupt them).

 

I'm not moving anything, what I'm supposed to do the prevent what you just told me?

 

Does this asset have a built in way to place decals onto a mesh collider?
Basically, I'd like to place these decals onto gameobjects which have a mesh collider, and no mesh renderer. Is that possible?

 

This is currently possible when using the plane projection mode. We have this feature on our roadmap (Alternative mesh sources). We can provide you with an evaluation version if you need to test the plugin in your ecosystem.

 

Hello doeas your asset work with tesselation, or parallax ? I would to use it with color map ultra shader 3.0 or cts terrain shader, Is that possible ?

 

When using the deferred projection mode it should work. When working with mesh decals the tessellated geometry is not accessible as this happens on graphics device level.

 

Is there a possibility that you will check it on any paralax shader? I'm using forward rendring in my cameras.

 

Actually, you can use parallax shaders with the mesh decals (basically, you can use every custom shader), but the generated decal geometry does not take tessellated geometry (of the decal receiver -> per example terrain) into account because the (e.g. DX11) tesselation happens directly on the GPU.

I hope that was not formulated too complicated.

 

I'm buying the asset on sale currently. The plane projection should work for me, because my meshes are quite simple, and it doesn't matter if it doesn't match the geometry exactly because the geometry isn't displayed. I will reply again if I can't get it to work properly in my environment.

 

I figure I must be doing something wrong with runtime decals.. trying to do blood splatter and it works great, but the GC is absolutely rediculous!
The only way I could seem to get run time decals to spawn and not distort was to use the following settings:

Spawning it using a simple raycast then this function :

Code (CSharp):

1. EasyDecal.ProjectAt(decalPrefab[num].gameObject, EasyDecal.DecalRoot.gameObject, hit.point, hit.normal, rot, new Vector3(scale, scale, scale));        

Any help would be appreciated. Thanks

 

There's nothing wrong with your workflow (unfortunately). But the box projected mesh decal has one disadvantage: its GC behavior when dynamically instantiating decals at runtime. This is caused by the fact that Unity provides no low-level access to the mesh data (e.g. using unsafe pointers). Each time the projector needs the geometry data that intersects its projection domain (bounding box) Unity generates a collection/array on the heap.

When having static decals or simple environment geometry, the Box projection technique is the way to go.
When having complex environment geometry and/or one have to frequently instantiate a lot of decals at runtime, one of the SSD techniques is more suitable.

I hope this helped!

 

How does Easy Decal allow decals to be placed on SkinnedMeshRenders? Does it allow the decals to be attached based on UVs?

What I would like to do:
1. Attach a decal at runtime to show blood on a animated SkinnedMeshRenderer.
2. Be able to setup the detcals at a predetermined the position, rotation and scale ahead of time (this is something I would code myself).

I guess that I would really like to know if your decals take into account UV's on SkinnedMeshRenderers so they are not moving around when the vertexs move.

 

Decal projection to skinned mesh works with the current version, but with the following restrictions:

1. Only one skinned mesh renderer per receiver
2. Only when GPU skinning is disabled

The decal gets positioned in 3D (world) space and then transformed into the local model space and weighted according to the present bones. The decal really becomes a part of the skinned mesh. Please write an email to our support when you need access to an evaluation version.

 

Thanks for the reply...will do that.

 

Hello, I have a question do your system works with LUX shader decals, What we woudl to achieve are decals under the snow lux shader has his own decal shader so It should work with your system, But Is there option that you will test that? Thanks

 

Everybody can request an evaluation version. I've sent you a code (in PM) that can be used in our webshop.

Merry Xmas.

 

Hey, nu-assets

I got this error. But I our game MainCamera is Set when game start. How Could I go around it;

 

Hi there,
The decal's transform observers get initialized in the component's OnEnable() method. This means that you have to have your main camera set/determined in the Awake() method.
When working with the source version you could also make the OnEnable method public and call it manually after your main camera has been initialized. When working with the precompiled version (basically the preferred version -> build time) you could also extend the EasyDecal class and write your own initialization chain code.

Please let us know if this helped.

 

Hello Thank you! Ignore my PM message I didnt know where to use that key

 

Okay!

 

Hi

I'm having some trouble getting the decals to wrap around the corner of a cube. It has a standard box colider.




Sometimes it doesn't wrap around the edge and sometimes it does but the image is badly stretched. Is this something I'm doing wrong or a limitation of the asset?

Cheers
Matt

 

Basically, you have two different ways to solve this:

1. Calculate an average orientation according to the involved faces. See the advance bullet hole example for reference.
2. Constrain the angle in the Constraints tab.

When working with dynamically placed decals it's all about a clever orientation (and some cheats angle clamping).

 

One question, can decals be batched by GPU instancing? It does not seem to work...dynamic batching works but not instancing.

 

Instancing does only work when having a shared geometry, meaning that on mesh gets uploaded to the GPU and gets instanced multiple time. The box projected decal generates a new mesh according to its location and intersecting meshes. Instancing would be possible using a quad decal.

 

Oh yeah forgot about that, but why do the shaders have the option at all? for place projection?

 

Unity provides a simple instancing "API" to enable easy per-instance properties from shaders. So this is basically a default behavior.

 

Hi, is it somehow possible to exclude colliders from having a decal projected on it? Other than using the layer Mask, I mean - maybe by using tags, or by adding a component. I'm specifically asking for Box Technique, so it would be okay if it would only work when baking.

 

In the current version, this is not possible. But when working with the source (downloadable from our website), you could add the following code to the Project() method of the BoxProjector class:

Code (CSharp):

1.             foreach (Collider collider in colliders)
2.             {
3.                 GameObject receiver = collider.gameObject;
4.  
5.                 if (receiver.tag != "Exclude")
6.                 {
7.                     processedIds.Add(receiver.GetInstanceID());
8.  
9.                     ProcessReceiver(receiver, 0, 0);
10.                 }
11.             }

But it's not recommended to have this change active at runtime because string operations are not cheap performance wise. Let me know if this solved your issue.

 

Thanks, that seems to be it. I'd actually only need it once, when baking the decal.

 

Hey again!

Placing the decals on colliders worked great. Now I'm looking into sorting the decals against unity sprites. My system uses 3d terrain tile colliders with a 2d image at the back representing their visuals.

In game camera to illustrate the problem

Here is the scene view.



the road decal should appear on top of the terrain image in the front there. It seems as though all of your decals are sorted at 0 in the default layer.

I can't find a way to edit their order in layer. One solution is to just set all terrain's sorting layer to one below default - but that means decals will be on top of terrain at all times, when they should technically be under things like cliffs.

Is there a way I can expose their order via script?

Thanks,

 

Hi! Great looking project!

You can access the active decal renderer and change the sorting layer there:

Code (CSharp):

1. EasyDecal decal = GetComponent<EasyDecal>();
2. decal.DecalRenderer.sortingOrder = 10;

Please let me know if this solved your issue.

 

Hi

Runtime instantiate is not working when collision object's layer used 31.
I have try at demo scene "scene_tunnel ".

Is it bug?

 

That sounds weird indeed. Do you get a specific exception message? Are you ale to instantiate other objects on layer 31?

 

Thanks for reply.
No message is output. I tried it in an empty project, but it will be.
When "Environment / tunnel" object layer is 31, decal does not instantiate even if decalPrefab of AdvancedBulletHoles is changed to other prefab.
layer 30 is fine.
ImpactParticles are also generated at layer 31.

I am using the following version.
Unity 2017.1.2p 4
EasyDecal 1.6.8

 

Maybe your implementation of ContainsLayer method is incorrect?
Would it work out if it is below?

return (mask & 1 << layer) != 0;

because,
Debug.Log(1 << LayerMask.NameToLayer("Test30")); is "1073741824"
Debug.Log(1 << LayerMask.NameToLayer("Test31")); is "-2147483648"
If layer 31 is included, it becomes negative.

 

Hi nu Assets,

I'm using Unity 2017.3.1. which the Decal Atlas region editor throws exceptions as follows:

and more like :

Could you please see to it because I can't modify the dll.

 

Hello There. Are the only shaders that work with Deferred option the Deferred SSD and multiply SSD? I can't seem to get any other shaders to show up when using Deferred decals. Its sort of a necessity to use deferred because I am placing them on a MegaSplat terrain that uses tesselation and Paralax. When using those shaders the decals to appear, but I'd really like my blood decals to have specularity so its shiny and has normal maps rather than just a red translucent blob.
Thanks!
