Change dissolve texture

[teacoat]

I have a bunch of UI elements that I want to dissolve one after another, change the text, and then dissolve it back in. This doesn't look great with the dissolve texture for each one being the same.

Is there any way to change the texture being used? Even more amazing would be something I can call on each UIDissolve to generate a new perlin noise texture on the fly?

Thanks for the great asset!

Hi, @teacoat.

It's good feature!
It is not supported yet, but will be supported soon, I think.

Now, I have two ideas.

Solution 1: Create new material instance with another noise texture.

You can use any texture.

Solution 2: Generate perlin noise in shader with some parameters.

Noise pattern is generated without material instances.
To send parameters to the shader, use UIVertex.normal etc.

If you want to do it immediately, please make the following modifications.

1. Comment out the ISerializationCallbackReceiver interface from UIDissolve.cs

public class UIDissolve: BaseMeshEffect
#if UNITY_EDITOR
//	, ISerializationCallbackReceiver
# endif

2. Create a new dissolve material

• Set the UI/Hidden/UI-Effect-Dissolve shader
• Set inspector to debug mode and set shader keyword according to ColorMode.
  (Additive: UI_COLOR_ADD, Subtract: UI_COLOR_SUB, Override: UI_COLOR_SET)
  
• Set your noise texture

3. Set the material as EffectMaterial and disable/enable component

Will this make the material texture in UIDissolve public and accessible during runtime to change textures as well?

It is possible by creating a new material instance.

1. Import above script to your project.
2. Add a ChangeDissolveTexture component to the GameObject contains UIDissolve.
3. You can change the texture from the inspector or a script like this:
   changeDissolveTexture.dissolveTexture = _your_dissolve_texture;

hmm.. I think that the noiseTexture property should be added to UIDissolve.

[teacoat]

A noise texture property and a method you can call to regenerate the noise texture would make this perfect!

I will try your other solutions sometime this weekend and let you know!
