► Advanced Dissolve ◄

I haven't opened it in my Unity yet. Right now I just have issues with the executable demo.
Unity version 2018.2 and OS is Win7 64 Bit

 

Sorry, I can not test demo on Windows 7 myself.

Hi. So I bought this asset recently, and so far it has been awesome, but I have two problems tho.

I'm Using Unity 2018.2.15f1. macOS Mojave, and building to Android min API 7.0. I'm using only VacuumShaders/Advanced Dissolve/Standard/Metallic.

The first problem is that there's a line (line 222) in the Specular.Shader (which I'm not even using) that keeps throwing an error on compile in unity. This is the error:

Code (CSharp):

1. Shader error in 'VacuumShaders/Advanced Dissolve/Physically Based/Specular': '_LightCoord' :  no such field in structure at line 222 (on gles)
2.  
3. Compiling Vertex program with UNITY_PASS_FORWARDADD SPOT _DISSOLVEALPHASOURCE_CUSTOM_MAP _DISSOLVEMASK_BOX
4. Platform defines: UNITY_NO_DXT5nm UNITY_NO_RGBM UNITY_ENABLE_REFLECTION_BUFFERS UNITY_FRAMEBUFFER_FETCH_AVAILABLE UNITY_NO_CUBEMAP_ARRAY UNITY_NO_SCREENSPACE_SHADOWS UNITY_PBS_USE_BRDF3 UNITY_NO_FULL_STANDARD_SHADER SHADER_API_MOBILE UNITY_HARDWARE_TIER1 UNITY_COLORSPACE_GAMMA UNITY_HALF_PRECISION_FRAGMENT_SHADER_REGISTERS UNITY_LIGHTMAP_DLDR_ENCODING
5.  

The second one is that I'm trying t bring this into ARCore, and so far it works, but when I have many meshes (sharing one material) and the mask is showing only a little portion of them, the frame rate drops to about 10fps and it looks painfully slow. Is there any workaround for this.

 

I was able to reconstruct issue with Physically Based (Specular & Metallic) shaders. Working on fix.
For now if you do not need those two shaders, just delete them.

As for frame drop, it mostly seems to be mobile GPU problem and how it handles Cutout shaders. Problem is widely discussed here on Unity forum.

Ok, I'm looking forward for the shaders fix.

So basically, there's no 'quick fix' for the frame drop problem... Guess I'll have to start digging the forums for more info then.

Thanl you for your response.

 

Hi, I purchased your asset and have been trying to use it with Enviro - Sky & Weather and it seems to just wipe out the entire weather effect and make the sky gray. Is this incompatible or am I doing something wrong?

 

May be you imported Demo Scenes package and it overwrote some already existing files inside your project? Before importing it check ReadMe file in the same folder.
Beside written above I do not think shader files can somehow "wipe out" anything in your project.



VacuumShaders - Facebook Twitter YouTube

 

I will try again, but by "wipe out" I mean stop the effect from working.

 

does this work with single pass VR or multipass ?

 

I just bought the shader today and was running quickly through the demo projects. I decided to import a truck into the plane demo and watch the body disappear away leaving the interior. Got the shader changed over with no problem. But no animation when plane passes over. I read earlier that a controller script has to be used, but no where do I find what I add nor where the controller is added to. I also searched YouTube for use tutorials with nothing. The docs explain what each thing is but not how to use it. Any help would be appreciated. In other words how is the animation added to the shader when the plane passes over the shader.

 

Check 3. Mask (Plane) example scene and Mask Controller object there. It has Controller_Mask_Plane script attached. All this script does - sending "plane' data to the shader.

As Dissolve shader can work with 4 mask objects, using this script you can send 4 'plane' mask data to the shader.
Which materials effect this script can be assigned inside Materials array.

If different materials need different mask object data, just use as many mask_controller scripts in the scene as you need.

If all scene materials use the same mask objects, it is better to check Global Controller inside all materials and mask controller script.
Check 8. Global Controller example scene and Mask Controller object there with the same Controller_Mask_Plane script attached.

Thanks for the response. I am in the 3.Mask file because I thought that would be easier to start than the cubes and spheres. Here is the workflow I used. 1.)Open Mask scene. 2.)import truck. 3.)duplicate CactusPack shader to CactupPack1 and assign it to my truck body. 4.)remove textures from slots and change the color. The truck is now partially invisible with the green gradient half way through it. But as I drag the plane I can watch my truck and shader and nothing happens. What am I missing. My thought was that I use an existing shader that way I would not miss any settings and then I would try and create one from scratch.


As I move the body it will transition as it crosses the stationary green gradient. You can see the plane well ahead of the gradient.



But the plane does not effect it.

I would like the plane to control the animation like you meant it to happen. I am missing something.

Thanks

 

Ok I found it. I needed to add the shader to the Mask controller.


Now the plane is the control of the new CactusPack1

Thanks

 

Yes, you just add materials to the Materials array and script will update them with required 'plane' mask objects data.
All other controller scripts work exactly the same way.

Hi! Just popping in to say thanks for this, I had the same problem and this was what solved it!

 

After importing demos in Unity 2018.3.0, there is an error message in Console:
Assets\VacuumShaders\Advanced Dissolve\Example And Demo Scenes\Demo\Files\PostProcessing\Editor\PropertyDrawers\MinDrawer.cs(6,34): error CS0104: 'MinAttribute' is an ambiguous reference between 'UnityEngine.PostProcessing.MinAttribute' and 'UnityEngine.MinAttribute'
Any idea, how to fix this?

 

Shaders work with Single and Multipass rendering methods. Tested on Oculus Rift.

Replace file with attached one.
The only difference is changing MinAttribute to UnityEngine.PostProcessing.MinAttribute
Or just delete that file. Will not effect Demo scenes.

Thanks a lot.
Now the Demo scenes works without any problems.

 

Hi,

I've been using your shader for some time and everything has been working properly until today:

I am making a scene where two meshes of similar size are overlapping, the one underneath has a normal unlit shader and the one on top uses the dissolve unlit shader. And then I have a cube that just moves left to right so it reveals what is inside the mesh.
Everything is working fine here. However this entities are parented to the camera, and I've added a simple animation to the camera that makes it navigate and rotate around the scene.
Once that is happening the shader starts to behave wrongly (I can see the edge of the shader popping in an out and sometimes the cutout is vertically instead of horizontally).
Tracking the entities in real-time I cannot see any entity misbehaving, the "dissolve box" keeps moving correctly relative to the camera.

I am using the code on the demo example, and I suspect something is not working properly in this line:
Matrix4x4 trs = Matrix4x4.TRS(m_DockBlender.position, m_DockBlender.rotation, Vector3.one).inverse;

Please could you advise on how to solve this issue.

Many thanks for your help and merry Christmas n_n

EDIT: I made a little demo using Unity 2018.2.3f1 (64-bit) in Windows 10. I shared the download link in a conversation with you. Alternatively please let me know how I can share it with you (bear in mind it includes your dissolve shader asset)

 

Problem is not with
Matrix4x4 trs = Matrix4x4.TRS(m_DockBlender.position, m_DockBlender.rotation, Vector3.one).inverse
it sends objects world Position and Rotation to the shader (in your case m_DockBlender object). To make sure it works correctly disable your custom animation and manually rotate and change parent object position (even in Play mode) - see it works and Box mask data is correct.
Problem begins when animation hits. How it overrides or effects child objects world Position and Rotation, and why they are not correct after animation, I can not say.

Thanks a lot for your fast reply, your message help me figure it was a Unity issue and not from the shader.
Just in case anyone has a similar issue I fixed by changing the Update Mode in the animator component to 'Animate Physics' (any other option has the wrong behavior on the shader)

 

local XYZ mask for material on particle system doesn't work.
its work like world XYZ mask

 

Particles are generated directly in world space by Unity, they do not have 'local' position.

Hey there and thanks for such a great asset
But i think its not working at least on 2017.1.f1 when i import package it gives many errors (unknown shader channel count) and whenever i play a scene theres too many missing prefabs on my hierarchy
Except the demo files from black smith they play nice but again the main reason for using this asset (dissolve effect ) is not working its only a wood house and some lights around it
Check the attached file bellow

Can anyone help please?

 

Seems you are using Unity 5.6 version of the asset.
Update Unity to 2017.4.10 (or later version) and re-download asset.

Hello,
This asset is awesome,
Is there a way to apply a material to the cross section of the cut? Just like
https://assetstore.unity.com/packages/vfx/shaders/cross-section-66300

 

Hey,

I'm sure I'm just doing this wrong but I am running into a small issue to do with the Mask Count variable.

I have a standard shader material (for example lets use standard metallic) with a masking type of box / plane / cylinder and a count of two/three/four. The material is assigned as a material on the respective mask controller object component for whatever type I am using. Whenever I enter play mode, the count will always reset to one. I can manually set the count both in the editor before playtime, and during playtime to be whatever I want and it behaves fine. It is only when entering playmode that the count is reset.

I can remove the material from the mask controller object component, and the count will not be reset. I'm fairly sure I am stupid and doing something wrong here, but I just can't figure out what.

I've attached a small gif to illustrate this. Any help would be appreciated.

 

Can not answer now, need to make some research.

Seems some of the script you are using in the scene is resetting mask count inside material.
Check which one sets _DissolveMaskCount to 1.

Hello,
I'm trying to get the asset working in LWRP but it won't compile. Sorry if I'm missing something trivial.

Severity   Code   Description   Project   File   Line   Suppression State

Error   CS0246   The type or namespace name 'LightweightShaderGUI' could not be found (are you missing a using directive or an assembly reference?) 

And sometimes I get an error on this line.

 #include "LWRP/ShaderLibrary/InputSurfaceSimple.hlsl"

Also may I know what the "VacuumShaders.dll" contains. I wish to use this as an opportunity to learn how to write complex shaders and was wondering if it contains implementation or if its not related to the dissolve shaders.

Thank you very much for the active support!

 

Very nice. Is it mobile friendly?

 

Thanks for the reply. The only script in that scene in the gif is your Controller_Mask_Box script. It is attached to the MaskController game object, which is just an empty with no other components.

All of the other game objects are just simple primitives with no scripts attached. I made that test scene to try and discern what was going on. It is as bare bones as possible.

 

I should add as well, that if I remove the shader material (that is applied to those spheres) from the Mask_Controller_Box script, then the count does not get reset to 1 when entering playmode. That is the only place the material is referenced by any script within the scene, and when removing it from that reference, this issue does not occur.

I've remade that scene and attached another gif to help. Is this a bug?

 

Alright I've found the issue. Inside all of the Controller Scripts, the count is being set to 1 in void start by this line of code:

Code (CSharp):

1. UpdateMaskCountKeyword(1);

As a band aid I've just commented these lines out for now. No more resetting of the count when entering playmode.

I'm surprised that no one has brought up this issue before. It seems like it would be a fairly common thing people would be trying to do.

 

Update for LWRP 4.0 and 4.6 will be available in several days. Working on it right now.

Package includes mobile: Unlit, OneDirectional Light, VertexLit shaders.
Performance also depends on used effects and there count. For example, shader with 4 dynamic box masks and triplanar noise mapping with enabled Global Illumination is more expensive than simple dissolve with one normal texture mapping.

Example scene on old Huawei Y330 (scene runs fast (38fps))

My mistake, mask controller scripts are used in example scenes where mask count is controlled run-time from UI, and in Start() function I just set it to 1 (just for safety).

I have about 300 materials and i cant remake all of them to dissolve materials. Impossibile to make two or more dissolve effects to object. Sent email week ago and still waiting answer. Want to refund =(

But it is most beautifull and wonderfull dissolve effect of all!!!

 

Would it be problematic to use this shader effect combined with Curved World? Thx!

 

Unfortunately I have not received any e-mails from you, or it may lost in spam. You can use Forum as well.

"I have about 300 materials and i cant remake all of them to dissolve materials"
- Advanced Dissolve is a shader collection. You have to replace shaders on your materials onto Advanced Dissolve shader.
If by "remake" you mean integrating Advanced Dissolve effects in custom shader, then I do not advertise such thing here.

"Impossible to make two or more dissolve effects to object"
- Not sure I understand what you mean here, try to guess:
1) If you need multiple dynamic mask objects to dissolve mesh, then with Advanced Dissolve you can use 4 objects simultaneously, main poster on the Asset Store is a proof.
2) If you mean multiple various dynamic mask types together, like Box mask and Plane, then you are right. Various dynamic mask types can not be used. (will add it to a wish-list for the future updates).
3) Beside dynamic mask you can use 3 textures (optionally) for dissolve effect and additionally dissolve from MainTexture.
I tried to implement as much possible dissolve options as I could, but of course, there may be situations where even those options are not enough.

Hello.
1) I have a player ship. I want it possibile to use teleport shader on at start mission first, second is damage dissolve at some part of the ship, a third is invisibility. And fourth is death.
2) i can add shader of your dissolve to much of materials, but all of them need to set parametres (

Is it possibile to convert shader to script like this ?

 

If material needs to be updated in run-time, there is no other way than use script (may be animation) and set parameters from there.
Check example scenes and controller scripts (Advanced Dissolve\Example And Demo Scenes\Example Scenes\Files\Scripts\Controllers) used there. They update all material parameters you may need.



VacuumShaders - Facebook Twitter YouTube

 

1) Is it possibile to convert shader to script like this without convert materials?
2) Is it possibile to make several effects types (damage, teleport, invisibility, ...) to one object without lots of scripts?

 

1) There is no way for converting shader to script. It is not possible. Seems you misunderstood something.
2) It all depends on what you mean in Damage, Teleport and Invisibility, what shader effects you need to have, how they will be updated and so on. Depending on that you may even avoid to use a single script or have lots of them.

As I wrote above, if material is changed dynamically in run-time, there is only one way to update its parameters - using script.

This is my ship
AT start of mission i want to use "teleportation" effect on it

At battle i want to dissolve some objects to show damage on it

But if it will be destroyed, then i want it to disappear from game area by this

3 different effects on one object. Is it possibly?
If it is destroyed, then two effects act on it simultaneously.

 

Which property should I use in Plane mask controlled scene?
I want to use material.GetFloat("which one") > =1, to check if the object is 100% invisible or 100% visible. Thanks.

 

This image shows using of dynamic Cone type mask,
and this is Plane or Axis type mask.

Only one dynamic mask type can be used at a time. So from those two effects you have to choose only one.


This effect is achieved using texture blend, and it can be combined with any dynamic mask.

You can not know whether mesh is visible or invisible, shader performs dissolve effect per-pixel on the screen.
You have to write custom script for checking all mesh vertices to be behind a plane.

Damn. Sorry but i want to refund =(

 

OK. Thanks.
