► Dynamic Radial Masks ◄

Hello!
I can't find the guide to make the dissolve effect (I work in Hdrp), can you plese tell me where to watch?
Thank you

 

Created with dynamic radial masks: https://www.reddit.com/r/Unity3D/comments/iuy44e/skychildren_of_light_inspired_cloud_shader_in_urp/

 

Dissolve effect is very simple to achieve using ShaderGraph. Just use resultant mask value in AlphaClip slot for the master node (may be it will need to be multiply by 2).

Hi.
I am updating my URP project with the last version and now seems is not possible any more create an Amplify Shader Function selecting Simple Algorithm or Global Scope. Every time I select these options the bottom menu disappears. Unfortunately, my project uses both. I am doing something wrong?
Thanks

 

Unity version? ASE version?

Hi. Sorry about the late response, I had to finish another project before return to this one.
Unity 2020.1.6f1 ASE 1.8.5
Thanks

 

Just tested with Unity 2020.1.8f1 (URP) and ASE 1.8.5 - no problems found.
Clicking on Amplify Shader Function button, creates ASE function file and it is highlighted in Project window.
Everything works as expected.


Try re-importing Amazing Assets folder.

Note, source code is fully included. Check DRMEditorWindow.cs file and if you can debug line: 95, here you can find generated file path.

You are right.
I haven`t realized we need to first click on create and only after that the other options will appear.
All is working fine.
Thanks for the quick answer.

 

What's the licensing regarding making shaders using this asset and then selling/distributing them?

 

You can not sell/distribute files from this asset. You can not include them in your asset and sell/distribute them. More info about assets and licenses is here.

You can create your asset or shader using this asset and then sell/distribute it, but do not include any of files from this package, instead make it this asset dependent.

Hello. Can I get a texture of colors instead of only greyscale texture?
(I mean each object has a separate color) (hoping to use this as some form of stylized multicolor lighting system)

 

Generated result is always float (not the grey-scale texture).
You use this value inside shader for achieving desired effects. What exactly are you trying to do?



Amazing Assets - YouTube Facebook Twitter

 

A custom lighting.
Imagine each radial mask object also has a custom data like a color (float3). I want to get a result as float4 there xyz is a color and w is a mask. I then can multiply this result with original colors and get recolored (lighted) objects.
[/QUOTE]

 

No, this is not possible.
Calculated result is not a collection (or array) of separate individual masks, instead it is the one value.

You can imitate similar effect by using several DRM objects (differentiate by ID) each one with different color mix inside a shader.

Can I use another shader material like FlatKit with Dynamic Radial Masks?

 

Yes, you can. If you follow instructions described in Manual file and do manual integration of this asset into FlatKit. Shader programing skills and knowledge are required for that.

If FlatKit shader is based on Amplify Shader Editor or Unity Shader Graph, then no shader programing is required, you just use DRM nodes inside shader graphs.

Perfect, I Buy this, thanks

 

@Arkhivrag - I bought your asset tried following the pdf and well.. I am still confused why I can't get it to work. I have Amplify Shader Editor.. I placed your Function into the editor.

Steps I did:
1.) Created Shockwave
a.) Count 1
b.) Alg advanced
c.) Blend Additive
d.) ID 2
e.) Scope: local

2.) Created Amplify Shader

3.) Placed Function into my shader

4.) linked mask to my Surface Albedo

5.) Added Vertex Position to WorldPos

6.) Built Shader out

7.) Applied Material to Shockwave Plane

8.) Changed material in DRM controller to New Material I created

9.) Adjusted DRM Controller script settings to match the shock wave ID 2 I created.

9.) Adjusted Shockwave DRM Game object script settings.. nothing happens.


Sorry, I am not a coder or anything by any stretch of the imagination. I am just a Graphic Designer/3D modeler… so that is probably why this is not working. LOL. I am using the example scene with all of the examples. On Shockwave plane. Do you have a tutorial video on how to set it up? If not I might suggest making one or make a menu for 1 click buttons like 1 click makes the material, scripts, function, amplify shader, etc.. so all you have to do is apply material to your model. Or make it a camera effect or postprocessing effect? That way you don’t use up the material for the model and you can use your own material and just have maybe a script that includes it in the radial mask..? Could you do dynamic radial masks with that? Like on raycast hit collider create hole? That would be cool, so if you shoot like lets say glass you could have a hole in the glass and have a decal to.. mask the mask. So that alpha on the decal would still allow you to see through it, but would be the broken decal on the glass.. I don't know again not a programmer.

 

Hey, I've got a question before I buy you're asset.

Can i get this kind of visual effect on the ground ? The line that limit the mouvement of the character. And the circle around the character in the middle of the screen.


Thanks for your reply, by the way, your asset looks very awesome.

You have to manually integrate DRM into a shader and use it as you want and need.

To make DRM visible inside material make sure DRMContrller script and DRM node in Amplify Shader have exactly same settings and target material is in the Materials array of the controller script.


There are several options (described in Manual file) how to generate DRM data that DRMContrller script sends to a material.
For example using DRMOnMouseRaycast method. This file creating DRM objects and saves them inside DRMAnimatableObjectsPool.


DRMAnimatableObjectsPool script can receive DRM objects from many various scripts. It collects them all and sends to DRMContrller script.
Make sure DRMAnimatableObjectsPool has assigned DRMContrller script.

If all this is correctly done, then DRMContrller will send DRM objects data to the material into the required node.


Some more tips:

• Enable Draw In Editor check box in DRMController script - this will draw DRM gizmos in editor and help you check if DRMController script receives any data from Pool scripts.
  
• Check Objects In Pool parameter inside DRMAnimatableObjectsPool script - displays total number of DRM objects in pool, sending to DRMController script.

 

Circle around character - yes. Line of the limit - no.

Note, DRM needs to be integrated into shader. Any kind of meshes requiring DRM shape projection need to have DRM property inside their materials. If you have several 'ground' meshes that character moves on, all materials of those 'ground' meshes needs DRM injection.
If the only purpose of using DRM in your case is drawing white circle on the ground, may be using post processing or image effect is better option.

Thx for your reply and advice, I understand how it works now. Thx a lot.

 

I'm trying to use the asset with the latest AmplifyShaderEditor (1.8.8), but I'm constantly getting an error from custom functions. Like this: "Custom expression "Read_DynanamicRadialMasks_Torus_32_Advanced-blah-blah-blah..." has a non-void return type but no return instruction was detected." I've already tried recreating the cginc and other files from DRM menu to no avail. Do you know what I'm doing wrong?

 

AS bug introduced in the previous versions and it seem it has not been fixed yet.
I'll try to find workaround.

[Edit]
Update with AS v1.8.8 support will be on Monday.

Hi! just wanted to ask a quick question.. does it support Lightmaps? Em using bakery for lightmaps in URP workflow and want to create something like the City>Forest video you have posted. Reference Picture is attached for what I want to achieve and if it requires shader editing, I have Amplify Shader Editor.
Thanks.

 

DRM is no a shader, it is an extension that you manually add inside shader. For ShaderGraph and ASE it is a node.
This node you can use to interpolate one value into another.


For example: DRM node here is used for interpolating between BaseColor and its saturated version.
Effect from screenshot can be created using DRM - it is created for such effects.

Is it possible to use this on unity terrains ? (not on mesh terrains)

 

DRM can be integrated in any type of shaders: common shaders, terrain, post processing.
But note, all integrations are made manually and you need to now how to modify Unity terrain shaders. Package includes example shaders only for common shaders, not terrain.

Ok, i'm looking into it. Thanks!

 

Hey there,

Great Asset!

I want to add another DRMGameObject to the DRMController. The Shape is Heightfield. When i add it to the DRMGameObjectsPool via AddObject it doesn't work. When i put the count of the DRMController to anything higher than 1 nothing works anymore. I'm using the example Scene with the Trees from the Asset.

Any chance to add another DRMGameObject to the pool on runtime?

 

1. You can not add DRMGameObject to the DRMController.

2. You can add DRMGameObject to the DRMGameObjectsPool (this script collects all DRMGameObjects data and sends them to the DRMController).

3. Make sure DRMController is setup to receive required amount of DRMObjects (Count parameter), also materials whose DRM properties are updated by DRMController must be using same Count of DRMObjects.

4. Increase DRM Game Objects array property inside DRMGameObjectsPool script and add required DRMGameObject there (editor window may need to be repainted for the effect to be visible, just update any property inside new DRMGameObject script).


In this example scene shaders can use only 4 DRM objects.

Hey there,

Thanks for the fast answer!

Steps to reproduce:

1. I set the count in the DRMController to 2.
2. On start there is already one DRMGameObject in the DRMController.
3. Via script I reference the DRMGameObjectsPool and add another DRMGameObject via AddObject.
4. Now not even the first mask is working anymore, nor the second.

 

Settings in the DRMController must be exactly the same as in materials they are updating.
You can check those settings directly inside shader node name:




If you are using hand written shader, check used method name:


Also check documentation chapter 5, page:18.

Allright, i will have a look into it. I was using your material though. Thought that would have been implemented already, my fault.

Thanks for the prompt help!

Another small question, i don't even know if it's related to your asset, but it happens since i imported it.

Is this a known issue maybe? This happens sometimes as soon as I scale up the mask. Its very hard to reproduce, but maybe there is some setting i have to do to prevent this error.

 

Error is not related to the DRM, pretty sure even not Unity itself.
You may need to update system libraries. Google will better help you in this case than me.

Allright. Thank you very much!

 

Hello, I need to create a wave of a color and when creating the next wave must be of a different color, if wave 1 is blue and I create wave 2 of red also modifies the color of wave 1. How can I do so that each wave has its own color?

 

Value generate by DRM node is not a collection of separate masks, it is the one value.
You can not achieve multi-color result using just one node. You have to use several DRM nodes each one for individual color.
Create several similar DRM nodes with different IDs, add them to a shader and with each node use desired color.
For updating each node inside shader use separate DRM controller based on its ID.



Amazing Assets - YouTube Facebook Twitter

 

I have duplicated the nodes as you have indicated but I noticed that the terrain sonar color is not multi-color, the result is the same color. Should I apply some other configuration or do you have an example I can base it on?

 

Duplicating DRM nodes inside shader will not work, as they are just the copy of each ones, they will generate the same mask value.
1) You need to create DRM nodes using editor tool. With similar settings, only ID should be different.
2) Use those nodes inside shader and multiply each one with desired color. Sum results.
3) Make sure each individual DRM node is updated using its own controller script (pay attention to the ID property value).

Here is example of using 4 identical DRM nodes. Each one generates similar Tube shaped mask, but as each one has different ID, they can be used separately.


Note, each DRM node inside shader needs it own controller script which updates its data. Property values inside controller script must be identical to the node's settings it updates.
Node name contains exactly this information.

Inside shader you can mix any type of DRM nodes.
Package includes Example_5_MultipleMasks example scene demonstrating how 2 different DRM effects can be mixed inside one shader.

Perfect! It's just what I need, it works great. Thank you very much!

 

Hey there,

is there any chance to get if an object is dissolved or not? i can't figure out which variable i could use for that. I figured maybe alphaclipthreshould but i can't access that directly. Any chance to figure out if an object is visible or not by code?

 

Mostly - No.
Shader is just an inscription for GPU how to draw pixel on screen.



Amazing Assets - YouTube Facebook Twitter

 

I want to dynamically deactivate a collider based on its visibility. Do you maybe know a way? I kinda want to create a level where there are two seperate worlds with your dissolve shader. For that i need to have colliders dynamically activate and deactivate.

 

You can just check radius of the used sphere object and based on this values decide further actions. If radius is big enough to cover entire 'world', then you can make assumption that it is completely dissolved.
But there is no any real ways for reading data from shader to check if pixels on screen are dissolved or not.

Hi, I have purchased your asset as there are some really nice features that will help with the visual effects, I have only just started learning to code shaders and wanted a bit of advice to integrate the dissolve feature into a terrain shader, the objective is to place a building and have your asset change the terrain visible under the building. Could you please help with any simple steps to do this?

Thanks very much

 

If you have just started learning shaders I'd suggest to practice DRM implementation into common shaders. After some practice it will be much easier to begin working with terrain shaders.
Download Unity built-in shaders based on your Unity version (link) and import terrain shaders from DefaultResourcesExtra\TerrainShaders\Splats folder. You have to modify 2 shader files there: FirstPass and AddPass, and their cginc file located in CGIncludes folder.
With terrain shaders always use Global DRM properties.

Hi there, thanks for making such an awesome asset!

I'm currently trying to solve for using dynamic masks to manipulate collisions, similar to what was responded to in this post - I'm assuming this is the right addon to do so, but not sure where to define the trigger as suggested.

As an example of what I'm trying to accomplish, using the 'dissolve' example scene between green/dead forests, right now if I apply collision meshes to those forests both exist regardless of which mesh is currently visible. I'm looking to achieve an effect where the mask also controls whether or not those collisions will be ignored.

 

You can differentiate meshes and colliders on those two "worlds", for example using tag or layer. And based on condition
activate or hide them. For example if mesh is inside DRM (sphere collider/trigger) activate its collider and deactivate those ones that are outside.

Awesome asset, how performant is this on low-mid level mobile devices?
