► Dynamic Radial Masks ◄

Each mask requires 6 - 20 mathematical operations, depending on the shape and type. On any device you can use as many masks as device can handle.

Here is Manual file describing how tool works and how integrate mask calculations into shader.

is it possible to use in VFX Graph? such as position map....

 

With VFX Graph - no.
Shader Graph and Amplify Shader Editor - yes.

Is this asset mobile friendly?

 

This asset has nothing to do with mobiles, consoles or PC. It is just a collection of methods (nodes) that you manually add to a shader for calculating radial shape masks. Each mask needs several arithmetic operations or instruction count (more info in the Manual file) and you can use as much those masks inside a shader as target GPU can handle.

Not sure what he meant with the latter part about position maps in relation to DRM mask unless he wants some super random positions, but i'm using DRM masks in VFX shaders in it's original intent with no issues. Is there some reason i ought not to or missed the discussions point?

 

My apologies, I'm definitely a noob when it comes to shaders. I came across this and fell in love with all the possibilities it offered, and tried to implement it in a mobile VR game I'm working on. Unfortunately, the performance with even the most "barebones" example shader made it impossible for me to use. Has anyone used this successfully on a mobile project? Could they provide guidance towards the simplest "Dot" or "Shockwave" shader that supports 1 lit texture with color tint?

 

Are you implementing it as a global feature or limited? You could go with local and only use it on stuff that is actually affected by it.

 

If you are using Amplify Shader Editor or Unity Shader Graph, I would suggest to check several video tutorials how to create simple basic shaders there.
After that, adding DRM node and adjusting it for your needs will not be a problem.

I'll give it a shot, thanks!

 

I was using it local, but some of the objects I was using it on were fairly large (like buildings)

 

I was planning on using DRM masks in a compute shader to update a Texture2DArray of all active masks on any given frame on the GPU and have the project materials then sample those in our shaders ( a collection of around 10 monolithic shaders that render nearly the entire projects geometry, characters etc ) instead of calculating the masks individually for each and every set pass in the scenes.

I have some limited experience in creating such, considering the DRM functions are designed to take absolute world positions as inputs, i'm wondering how i'd go about converting those into a version where each mask would write to a 2048x2048 texture instead that i intend to sample twice (horizontally and vertically).

My intention here is that despite pretty vastly increasing the number of texture samples in the shaders, in most cases it should still be quite a bit faster than calculating say 6-12 global masks individually for each and every rendered object so long as i balance the texture samplers evenly across all samplings.

Any thought's that come to mind regarding such or any other ideas that come to mind you could recommend?

We love your asset, i'd just like to go even more wild with it without impacting performance negatively, we're at 6 global advanced masks but that's the limit of our frame budget for these and we want more.

 

So you are asking a solution to render shader effect (requiring mesh pixels world space position) into a texture?
May be there are some methods and techniques, but I am not aware of them.

Hey I have a quick question!

So I'm dealing with an issue where the dissolve shader is causing some weird artifacting on overlapping objects. We wanted to have it where we have our player going back and forth between past and present, so there are city buildings that will more or less be occupying the same space, just with slightly different/more dilapidated looking models.

I'll have one version of the object on an inverted dissolve and the other on a normal dissolve, and it makes either one or the other (Depending on if I turn Recieve SSR and/or Recieve Decals on/off on the shader, not sure why) do this static-y looking zig zag pattern all over the object. I've tried slightly resizing and offsetting the conflicting objects, but this issue still occurs to some degree, and I'd like objects to stay in their relative place between switching back and forth .

I'm sure it's something I'm doing wrong, possibly with render settings, I'm just not sure what. I'm currently using the High Definition Render Pipeline. I've attached a gif of the issue on a test world I made just to show what I'm talking about.

 

It looks like some setting problem in your shade.
Do included example scenes have the similar problem?



Amazing Assets - YouTube Facebook Twitter

 

Yeah, the problem also happens with the example scene. I put down a box, duplicated it, and gave one the Dissolve Green and one the Dissolve Brown from your example materials. Now I did realize when they are right on top of each other, the box will just glow completely with one of the materials, and if I offset it just a little bit it will create the effect I showed you. I've included another gif to show that.

 

I was able to reconstruct that artifact at my side. It looks like some kind of ZWrite or ZTest problem in ShaderGraph for HDRP. No problems in URP.
Need to make some research, if it is possible to fix directly from ShaderGrpah.

Ah ok I gotcha! Yeah I just converted everything over to URP and just like you said no issues. That is incredibly strange, but thankfully I didnt really need the project to be in HDRP.

Really appreciate the quick response! Been loving the asset so far and its got a lot of nifty features that I can't wait to try out

 

Hi,

Firstly thank you for offering the very stylish and useful radial mask asset.

There is one qustion for the asset. I am looking for radial screen transition effect like this in the link below (at 6, 12 and 21 seconds in the video). https://www.youtube.com/shorts/w26igBKcS20

By using Dynamic Radial Masks asset, can I implement a similar radial wipe transition towards multiple UIs on Canvas for screen change?

Environment is...
Unity 2020.3.22f
A progect with universal render pipeline.

Thank you for checking. bb

 

Yes, it is possible, if UI element uses sprite shader (tested with ShaderGraph).


Note, package does not include example shaders for UI elements, but integrating DRM into sprite shader is the same as for common 'mesh' shaders.

Hi,

there is chapter 6. Calculate Mask Using Script in manual wich i find a little misleading since it is about getting the mask.
But how can i set the mask (per frame) from another shader or script?
I am calculating a fov with shadows and like to set that as a mask for the handwritten version.

 

You set mask properties inside DRMContoller script and based on that settings DRM is calculated inside a shader or in the run-time CPU method that is described in the Manual.

 

If I want to change DRMAnimatableObjectsPool setting value in runtime, e.g. Life Length
how can I do it in script?

 

DRMAnimatableObjectsPool script has no settings. It just animates list of DRMAnimatableObject, based on their settings.
DRMAnimatableObject has public property lifeLength, you can adjust it from script.

 

Hi, Sorry I don't know about shaders. I am using "liquid (Displace)" material. I want to change the base color with script but I don't know how. can you help?

 

Check property's reference name and then modify it using SetColor method.

 

great, thanks

 

There is no amplify shader node for URP?

 

All render pipelines are supported.

 

Yeah but when I am trying to use "DynamicRadialMasks_Torus_16_Advanced_Normalized_ID1_Local"
(not included in the "Universal.unitypackage" but in Standard)
in universal Lit shader by amplify shader editor, it always produces error in shader code like:

Code (CSharp):

1. Shader error in 'AmplifyRadialTest': undeclared identifier 'DynamicRadialMasks_Torus_16_Advanced_Normalized_ID1_Local_float' at line 561 (on d3d11)

When trying to use this node on standard pipeline like that (the only ASE node available in package):

on the liquid demo, nothing happens on the plane (I am changing shader of Liquid demo material to use the same references for components etc.)

Edit: Aaah ok, the Window -> Amazing Assets -> Dynamic Radial Masks window can generate ASE nodes

 

Which Unity version are you using?
Just tested with 2020.3 and 2021.3 LTS versions and everything works correctly at my side.

 

Sorry, I got confused and I was using just the ASE node included in the examples package.
I found I can generate ASE nodes in the Window -> Amazing Assets -> Dynamic Radial Masks Window
and it works right now! (unity 2022 URP 14)

 

How would this work with terrain in HDRP?

 

If you integrate DRM inside terrain shader, it will work as you want.

 

Tessellation is now available on the HDRP, but it seems that the vertex displacement is happening before the tessellation takes effect. Any idea on how to make it work?

 

Instead of adjusting Position input, use Tessellation Displacement.


If you want to add tessellation to the package included vertex displacement example shader, it may not work correct as you will have to adjust vertex displacement math there too.
