Light Beams

Hello

I released small, performance cheap light beams shader pack.
Use them for light shafts / beams or laser beams or else.
You can control fading distance and light shaft intensity and softness.
Also you can combine it with script which prevents wall penetrations.

Few pictures.






Thank you.

 

and where can we get this?

 

You can get it at: LINK
( and edited first post )

 

How performance on mobile?

 

Well, its transparent shader so it has its dificulties. Its not using lighting though.
I uploaded .apk package on dropbox so you can check for yourself:

Here is another video with setup tutorial
And I updated to new version with some improvements.

Hi, I am interested in this asset, I'd like to ask a question first if that is ok: If there is an object blocking the volume light/beam will the light stop or pass through the object? Will this true/false also if the object only is partialy blocking the light beam?

 

Apologies also, to ask will this work the now older unity 4.6?

 

There is a script in the package which prevents passing through blocking objects.
Its not working for partial blocking ( at least for now. ).

 

I'll get back to you on this.

 

Thanks for your reply, I'd like to use this for a car's headlights, so lampoles etc could be passing in front of the lights, I'm hoping or partial blocking, maybe if I bunch your volume lights into one then this could be achievable?

 

Many thanks, much appreciated

 

Partial blocking on pixel level is in my future update plans, but for now it is how it is :/

 

OK, all shaders work.



Only you'll have to delete all Unity 5 generated stuff, only keep models, shaders, textures and beam control script.

 

Awesome, thanks for testing!

 

We're having a problem with the shaders on Kindle Fire devices.

Notice the lightbeam from the headlight below, looking patchy with the abrupt gradients.

Are there suggestions for a fix ?

 

Can we please continue on private inbox or email.
What Unity version are you using?
Kindle Fire is android, yes?
What graphic API are you using?
Are the scenes in the package working ok?
Are you using some post processing effects?
What rendering path?

 

My 0.2 cents..Hmm, isn't that just a kindle graphics gpu issue, have you tried the game on android, does do the same thee, just wondering.

 

I'm getting compiler errors right after importing the asset, in Unity 5.6.1f1. For example:

Assets/_LightBeams/Standard Assets/ParticleSystems/Scripts/WaterHoseParticles.cs(41,48): error CS0619: `UnityEngine.ParticleCollisionEvent.collider' is obsolete: `collider property is deprecated. Use colliderComponent instead, which supports Collider and Collider2D components.'

 

That is standard assets incompatibility errors between multiple versions. I'll remove standard assets folder and submit update.
Until I update you can use standard assets from your version of unity or remove scripts which are not in use ( like waterhose script in error message) or fix errors.

 

Hi, I just bought your asset. as I needed a "light" volumetric effect. It's very nice from the sides, but disappears when viewed upfront. Is there a workaround for that? Thanks.

 

That may happen when light beam is narrow and looked upfront, yes. You can widen the beam to fix this.

 

Hello, does this work on Windows Store and WebGL builds?

 

Yes, here is mobile ( android build ) example DROPBOX LINK.

 

Hi, does this still work in 2018.3 ?

 

Yes, it does

 

Thanks for this, working fine in 2019.1!

What I'm wondering: Why is "HideInInspector" set on the shader's Color property? What's the intended way of setting the color and is there any problem with removing that attribute and editing it right in the Inspector?

 

Because there is custom inspector editor which displays HDR colors.

 

is it also possible in unity 4.5.4 ? have already chewed the asset but it doesn't work and the shaders are pink even if I add a material Lg


undeclared identifier 'UnityObjectToClipPos'

 

Unity 4.5.4? Oh boy!
I think you need to replace 'UnityObjectToClipPos' with manual calculating of clip space ( or equivalent function from that old Unity version )

 

I use the old version because I can handle javascript very well so far. i have now also tried with 4.6.1f1 the shader swork still does not work :-( I made it as described above deleted everything that is for the unity5.

 

Vertex shader for light beams is same as most vertex shaders - it does nothing special.
It just transforms position.
Try to replace 'UnityObjectToClipPos' with
'mul (UNITY_MATRIX_MVP, In.pos);'

 

Thank you I'll try

 

Hi, I bought this asset today. How can I use this in URP? It looks just so pink..! Please help
