[X-WeaponTrail]The best weapon trail solution for unity.

Hey, just add x-weapon trail to my game and it was creating two trail meshes. Is there a reason you set mInited to false in Start? Init already gets called in OnEnable, so forcing it to call Init again in Start creates a second mesh. I commented out the part in Start and it seems to work fine.

 

emm..
I do remember I added that tricky code for some reason....
If you commented out that line, when you instantiate weapontrail from prefab may not work properly..
sorry for the inconvenient I'll try to find a better solution.

 

I have the weapontrail as a child of a prefab that gets instantiated, and editing that line out seems to work perfectly. I also had to edit out the line in Deactivate that disables the actual gameobject, as I have the weapontrail as a child of an object that gets disabled, but when I reenable the parent the weapontrail doesn't reenable. Hope that makes sense. I got it working in my case, but I assume it will break other use cases.

 

Hi, I used this in VR with singlepass, but the trail become black. how to fix this?

 

Hi, Sorry for the late reply.
Currently I have no VR device to test it, But as far as I know it works with VR.
Are you using the distortion material? I guess that may be the problem.(this material uses grab pass and that's not recommended because it only works under some specific project settings.)
Try using other material, if the problem still exists please give me more detailed information.
And if I didn't reply within 1 day please send me a email..
Regards,

 

Question about continuity on trails. I'm combining red and distort trails for my weapons. I was wondering if you knew the cause of why sometimes the distort falls behind the red, or looks smaller, even on a blank stage (distort pulls from the image behind, right?). Above picture is correct blend. Below is what sometimes happens. The end points are identical or for some moves I've put the red end point behind. View attachment 468635 View attachment 468638

 

Hello,
As far as I can see I think there are too problems in your weapon trail
1, The background's color is too pure, the distortion may not take effect
2, The distortion strength is too large, try reduce it in the material.
as you said the distortion pulls from the image behind, but it also add offset to it, so in the second texture, the distortion is taken from other area which color is pure gray.

 

Hello, Shallwaycn.
I'm using your asset very useful.

But I have a question.
I am using XTrailWeapon in LWRP project.
When you check the SRP option in XWeaponTrail 1.4.3 and use it, a new object is created in Scene called _XWeaponTrailMesh:|material(name).

Did I set something wrong?
Or is this your design intent?
If this is your design intent, please let me know why SRP options require you to create a separate meshObject.
LWRP is still too difficult for me.

Please reply.

 

Hello childcat,
The XWeaponTrail uses Camera.OnPreRender() to draw the trail immediately, but this method not work in SRP, so in SRP the trail is rendered by mesh object but its rendering has one frame lag.
Hope this helps,

 

quick question, how to make trail only active when model attackt?

 

just set the weapon trail game object's active state to false while not attacking should work.
you need to set the state by script or animation event manually.

 

Will there ever be an alternative distortion shader for LWRP?

 

The distortion shader uses grab pass, but it seems the grab pass is still not stable in LWRP, in some Unity version may not work.
Even it works with LWRP it's still not recommended due to the performance issue.
There seems have some cheap solution for distortion, but I'm not sure if it works with LWRP, I'll take a try but it's not a priority task..

 

Hello, shallwaycn, quick question.

Is there a way, through code or some settings, that I could make the trail 'disconnect' from the mesh it's attached to after a certain point?

So basically, when I attack, I want the trail to do what it normally does, trail behind the sword, but when the sword's animation is done, I want the trail to exist in the world scene, even if my sword is somewhere else now, etc.

As in, "trail disconnects from sword after attack animation completes".

Any idea how I can do that?

 

I can show you a reference video if you want.
There's certain bosses in the game Sekiro: Shadows Die Twice that do this. They do a large slash that has a trail, but when the slash is done, the trail lines stay in the air for a bit and the sword doesn't add onto the trail.

 

Hi,

I'm afraid currently this is not supported.

If you really want to do this you can add a "pause" flag in the Update() function, and set pause to true and force update to return when you disconnects the trail.

However I haven't tested it yet.

 

I use SRP. So should I pause both Update() and LateUpdate() since they both run a Pre/Post Render function?

I'll try this tonight.

Overall, though, great asset. Love it.

 

I played around with it.

I realized I don't need to pause Update(), I just needed to pause RefreshSpline() which is called in Update().

Pausing Update() pauses the fade-time variables and the vertex updates for fade as well, which I still need to work.

I used a "pause" flag, and changed the line of code in Update() to this:

Code (CSharp):

1. if (!pause) RefreshSpline();

Then in Activate(), I added this:

Code (CSharp):

1. pause = false;

I set pause to true through animation event.

 

Hi,
Is this asset also available on the timeline window?

 

Any Plans on supporting HDRP?


Edit: Kinda got it to work. Turn on option for SRP. I changed shader to the sample HDRP particle shader ParticleUnlitDistortion and its close to the standard Trail you have

Edit 2: ParticleUnlitSoft seems the best

 

is there anyway to make this only be affected by motion in local space? If my character moves while swinging, the trails will be affected by my character's movement and jump around a lot. Seems like a huge oversight for a first person melee combat game.

 

Couple of months ago I discovered the start of the trails aren't in sync with my animations and felt like a frame lag. Like the trails can't catch up to the blade. And the rest of the trail are like a frame average of the swing positions, making it muddy.
I wanna clarify if anyone finding similar results and I solved it by moving 'MyPreRender(MyCamera);' line of the code and it's now working as intendent.
I'm using HDRP currently

Code (CSharp):

1.         void Update(){
2.             if (!UseWithSRP){
3.                 return;
4.             }
5.           //  MyPreRender(MyCamera);
6.         }
7.  
8.  
9.         void LateUpdate(){
10.             if (!UseWithSRP){
11.                 return;
12.             }
13.             MyPreRender(MyCamera);
14.             MyPostRender(MyCamera);
15.         }

 

Hi all,
Sorry for the late reply.. I don't know why I didn't receive the reply notification from Unity since a long time ago..

@lenzchu
Thank you for the solution, I'll test it tonight, If everything goes well I'll update a new version soon.

 

Has anyone tested this on mobile?

 

Hi there should be no problem on mobile.

Most of the users including me are using this tool on mobile project.

 

That's good to know. Have you tried testing on some low end mobile phones?

 

Hi again! I discovered multiple xWeaponTrail gameobjects lingering in the hierarchy when destroying or instantiating one of my weapons a couple of times. I'm not sure if I've been doing this correctly that results in this flood. Is there a way to clean this up?


Many thanks!

 

Im using Unity 2020 ,shader: Xffect/displacement/screen only zhis one cant work, how can i fix it

 

Hi, I am developing for VR, is there a way to the sword trail for locomotion, and only activate it during attacks?

 

Hi, I'm running into issues where, at times, the trail will appear to begin from very far away. Almost like it's beginning from the origin or someplace else. Are you aware of the issue? Is there a workaround? Thanks!

 

Can you do a HDRP shader for the distortion materials

 

There's a very simple way how to do distortion material now (at least with URP 12+)

If you use Universal Render Pipeline/Particles/Unlit material, you can now use Advanced option Distortion. See screenshot for possible setup how to do it (the most important thing is the normal map that actually does the distortion)

Additional info is here https://docs.unity3d.com/Packages/c...ersal@12.1/manual/particles-unlit-shader.html

(I'm very happy I can use this now, working with shader graph is pretty complicated)

 

Hello! I recently purchased X-Weapontrail and it is not working for me either on the provided demo scene or in my game. There simply is no trail effect. I don't see any errors anywhere to indicate what might be going wrong. I am on Unity 2020.3.25f1 and URP 10.7. Any idea what I might be doing wrong?

Also I should note that I am instantiating my weapon at runtime. I've confirmed that it has the X-Weapontrail prefab and it is activated, but nothing is happening.

 

I use URP and I got it to work by checking 'Use SRP'

 

Hi @shallwaycn , I bought this asset as it said it works with HDRP on the Unity Asset page description. Any official guide how to get it to work including the distortion effect?

 

try check "Use with SRP" box to true

 

hi @shallwaycn im using URP on Unity 2020.3 and 2021.2 and the distort material is pink. how to fix this?

 

SRP box doesn't fix all for HDRP. Distortion shader doesn't work as it was advertised. It's highlighted to be an HDRP on the store page but it is not really. it is a bummer there is no real support. I am not into bad reviews, especially for a little update that could be done by the creator in little time to the asset... I'll consider this lost money then :-/

 

And the website with the docs are down. So, I think that says everything right there.

 

Help me! I have the trouble with curve sword. how can i solve this problem

 

For me, I changed the Activate() function.

Commented out the Init and reset the mSpline instead

Code (CSharp):

1.             //Init();
2.             foreach (var cp in mSpline.ControlPoints)
3.             {
4.                 cp.Position = CurHeadPos;
5.                 cp.Normal = PointStart.position - PointEnd.position;
6.             }
7.  

 

You just need to create the proper material. You can download the HDRP sample shaders in the package manager and that can give you many options.

I have a couple done, This is one example
