Easy Decal - Decals everywhere

The cut-off shaders work also out-the-box because they get rendered before transparency.

 

Version 2020.2.5 has a dedicated background-color setting in the Preferences.

 

Are SSDecals for URP working? I cannot make them work. I can only use Easy Decal/Particles/Alpha Blended shader and it works:

but I cannot follow the SSD pipeline using any of the SSD materials.

 

It's caused by a Unity bug. https://issuetracker.unity3d.com/is...d-when-using-universal-rp-7-dot-4-1-and-newer
Please vote on the issue so that we have this fix released asap.

 

He anwers very fast on mail

 

so far It doesnt seem to work or to react to light probe. they just "pop out" instead of being blended in the scene... ill try different variation

there is also a nasty bug when you have 2 decals on top of each other, depending on the angle you look at them one will pop over the other one despite that they are physically on top of each other and not exactly at the same coordinate

 

Have you enabled the lightprobe option? You can also always access the decal mesh renderer to control settings that may not be exposed usingthe component UI.

That's not an actual bug, but a result of planar faces rendering pixels in the same location - it's called z-fighting - pixels fight for their z-position in clip space. This can be avoided by offsetting decals in normal direction with the Distance porperty.

 

@Sycoforge @BitAssembler Hey there, Easy Decal doesn't seem to work on Unity 2020.2.0 that was released this week. Is this a known problem? Thanks.

 

There's a known issue with screen space decals in URP in Unity 2020.2. The mesh decals are successfully tested in 2020.2. What issues are you experiencing?

Edit: The URP 10.x content is downloadable from our website.

 

@Sycoforge there was a red timeout error involving Easy Decal, but turned out it was a conflict with NGTools, an editor extension, been sorted.

 

Glad to read everything's working!

 

Does Edit -> Project Settings -> Quality -> Anti Aliasing works without URP/HDPR package?

 

I want to generate a Skinned Box system at runtime, but it doesn't work.
I used AdvancedBulletHoles.cs to set the SkinnedBox on the Decal Prefab.
The decal is not projected even though it is generated in the correct position.
Calling LateBake () didn't work either.
What else do I need to do to generate a SkinnedBox system at runtime?

 

Unfortunately, skinned box decals are currently design-time only. You can find a quick introduction here.

 

Thank you for your quick reply.
Are there any plans to implement runtime generation in the future?

 

Yes, skinned mesh projector for runtime usage is on the roadmap, but we can not give an ETA. Currently, we propose to place a bunch of damage decals at design time (kind of damage areas) and enable/disable them on demand. This involves more setup steps but in return, it's super great for performance.

 

When projecting using the Skinned Box system.
Is it possible to respond to changes in BlendShapes?

 

Blend shapes are currently not officially supported and may lead to weird and unexpected results.

 

Hello there,

I have a mobile car game and I want to add car sticker modification with Easy Decal.

I have some questions;

1. The car is constantly moving by the player, so it's not static like a wall. Is this possible for the Easy Decal mobile vehicle project?
2. What features should I use for mobile?
If I choose the Box technique, Everything can be done very easily and looks perfectly on my computer, but I have a serious performance problem on my mobile device (2 - 3 Fps). Texture of Atlas sticks to the car perfectly.

If I choose the Plane technique, the Texture of Atlas does not exactly stick to the car and the texture is constantly appearing and disappearing during the gaming scene. But my game does not show any performance issues on mobile.

3. Should I pay attention to an adjustment in Unity Light Rendering screens for a performance run?

Thanks,
Tayfun

 

Have you baked the decal? Once parented and bake to the car, the baked should consume almost zero CPU time.

 

Z fighting issue when decal overlap

I used Easy Decal/Ed standard shader and i still get flickering issue.

For context, I have enemy vomit toxic projectile at player,
when player evade, projectile hit the floor and spawn decal at floor.
If multiple of same projectile hit the floor at same position, multiple decal is projected
at same position and flickering happened.

Currently I offset the decal distance by increment distance by .001f for each decal instantiate
but this feel like hack.
Am I missing something?

 

Offsetting decals is the way to still benefit from auto batching. The other way is to offset the material in the render queue, but this creates a new instance which then leads to a new draw call per decal. A further option is switching to a commutative blending equation such as "multiply". However, multiply is more related to blood effects.

 

I've been having some issues lately with the decals not showing up in the android build, even though they work in the editor. Any decal that's placed directly in the scene seems to work fine, but the ones that are attached to an instanced object just dont work. They used to work, and we have not changed any settings since they did. Any idea why this happens?

 

Can you double-check whether the shaders are included in the build? You can add the shader in question to the Always Include list in the Unity settings.

 

@Sycoforge Hi there,

ever since I switched to Unity 2020.3.3f1, I am getting weird console errors:



I am on Easy Decal version 2019.2 and using built-in render pipeline.
I am using mostly baked Box decals and a couple of SSD decals.

Any hint & help would be greatly appreciated as we're close to shipping our game.

 

Thanks for connecting. Do you have any skinned box decals in your scene?

 

No, they're just regular box decals, here's the config:



I get the error every time I save the scene or enter play mode or build the project.

I am not using skinned meshes in any way in the entire project.

UPDATE: Upgrading to the latest version of Easy Decal did not fix this.

 

I'm using a Box decal to fake a shadow under a character. I recently switched my character to move on FixedUpdate, and now the decal jitters up and down significantly when the character jumps. Does easyDecal use the Update method? Is there any way to switch it to use the FixedUpdate?

 

Yes, the system calls project in the Update() method. You could get the source code on our website and make the changes yourself. However, we cannot give extensive support when altering the source.

 

Thanks for the additional information. Until now, we have not been able to reliably reproduce it. However, we have received a similar report some time ago, where this error got thrown too, but there was no impact in functionality. I guess, you do experience the same issue here, so it's safe to ship because it's an error message not an exception that interrupts the system in the build. We do further investigation on this.

 

Thanks for looking into it, a fix would be *greatly* appreciated, as it's a super annoying bug. It throws an error message literally every time we do anything.

Might have had something to do with me disabling game object hierarchies that contained Easy Decal objects, saving the scene, then re-enabling them again. The error only occurred until after I re-enabled said gameobjects with decals on them, SSD decals to be more precise.

Update:

Upon reimporting all assets, I get a BUNCH of shader warnings, too:

 

Yes, the shader is in the always include list. Is it something you have to do when the object it's attached to is instantiated? Since the ones that are placed directly into the scene works.

 

Are you URP? If yes, try enabling Depth Texture on the camera.

 

Yes, sorry, we're on URP 2020.1.5f1. Depth texture is enabled.

Apparently the android log says that the game objects have missing or unknown components. I get no errors or warnings in the editor though.

 

Hard to tell what's going on there. Can you do a minimal demo scene just including one decal and build again? Maybe in a fresh project?

 

Hi!

I've been using the Easy Decal plugin for a bit. It's really great, thanks for making it!

I had a few questions regarding the hard bake functionality (reference image attached to show exactly what I'm referring to):

1) Is possible to detect when the Save as Assets: Save button is pressed via script through an event trigger, callback or anything else.
2) After pressing the Save button, I also wanted to save the file at a specified path via script as opposed using a Save Window, is there a wat to do that?
3) Finally, can we access and modify the Instantiate after Save toggle via script?

Thanks!

 

Thanks for your nice words! Currently, there's no callback for those editor-based flows. However, you can do all those changes in the source. You can hook into the following method in the EasyDecalEditor.cs file

Code (CSharp):

1. private static void CreateDecalAsset(EasyDecal original, bool instatiateAfterExport)

Hope that helped!

 

Hello,
I want to use Easy decal on an object with LOD group.
However, this decal will be projected on all LOD
Cull invisibles is on and the technique is using Box
i'm using Unity 2020.3 + URP

Easy Decal doesn't work properly in Unity LOD Group?

 

The proposed LOD workflow is as follows:

1. Project decal to ever LOD level
2. Hard bake decal for all levels
3. Assign the decal renderers to the respective LOD group level

The other solution is to restrict decal receiving to LOD0. Otherwise, the decal would have to project every time the LOD changes, which would an overkill.

 

can i use it in urp project?
it works fine in build-in project.
all the shaders are in build-in pipeline, i change my project to urp, can i still use this?
now all the effects are missing, what should i do?

 

Yes, you can. You have to import the extension packages shipped with Easy Decal.
Import them in the following order:

1. easy_decal_URP_content_2020_2
   
2. easy_decal_URP_content_2020_3

 

thx for reply.
i still got a question. that is in urp project. will the decal have different reaction in different light condition like other materil with shader wirten in hlsl. cause we are using it for makeup which might require good quality.

 

In URP, we have no deferred rendering, thus no g-buffer based lighting. So unfortunately, decals can no blend with normals of other shaders.

 

thanks for your reply. its a good decal plugin anyway! ! it makes our job much easier

 

hi, can the decal be used on a mesh that will deform during runtime? if not can I bake the decal to the texture beforehand in editor? thx

 

Anyone have any performance issues on more complex mesh when applying during runtime? I ran the profiler and it looks like EasyDecal.Update() is running at 99 percent and it looks like it's BoxProjector.Project -> MeshCutter taking up the majority of the resources then it's BoxProjector.ProjectUsingEnvironment.

Would there be a way to not apply it every frame or as a coroutine to not freeze up the game? My use case is a little different though where I don't need the decal to apply immediately and can have the user wait a second or two to update as they apply the decal.

Maybe I can get some suggestions on applying decals to a more complex model?

 

Hey All, anybody know if there is a way to prevent a screen space decal stretching up the side of geometry that is parallel to the projection?



The box and plane projection method don't seem to work at all for our project.

I was thinking it would be good if you could modify the opacity based on the depth of the projection you could "fade out" the stretch marks which would look OK for an explosion scorch mark. Do you think that would be possible by modifying the shader somehow?


update:

I found this with some side stretching prevention built in.

Hey.

Using HDRP and the Box technique, decals cast shadows. For the attached image, the 'Distance' setting has been increased to 0.1 to make it more obvious to see.

Anything I or you can do about this?

 

Hi, is there a atlas texture pack for this asset, I am looking for a bunch of rust/dirt ones, any help would be welcome.

 

Hi!
I'm using the Builtin Render Pipeline and the forward rendering path and wanted to know if it was possible to achieve something like the HDRP decals, feature-wise, which are then created at runtime and not design time? (Supporting this for static scene objects is enough)
More specifically if there was a way to have lighting support for screen space decals on the forward rendering path? Or if this was impossible?
If it wasn't impossible, how could that possibly be approached?

Looking at the URP lit SSD shader parameters, it would also be great to have normal map, emission map, AO map and metallic + smoothness support. But the lighting support would be the most important feature for me here.

If it's hard or nearly impossible to achieve this, I'm curious what URP features to make this possible (I haven't tested it yet, but it looks like the URP lit SSD shader would work for forward rendering?)

If there is no way to achieve this, I might consider switching to the deferred rendering pipeline, but having less usable stencil bits to work with for custom features and possible transparency issues make this a tough choice.

I also tried to play around with the box projector, the Standard ED material provides me with all the properties I want but I couldn't get the projection results I wanted. Trying to get it to behave similarly to how the screen space decals wrap around the visible geometry for the full volume of the projector box probably can't work I assume? (Since there is only a projection in one direction etc.) And when it doesn't check against only colliders, the meshes from the reflection probes are included in the projection surfaces too (I guess I could deactivate them until the baking process has finished)
