accessing shader variables?

How can I access variables and properties in a material that are part of a special shader?

Like I grabbed this dissolve shader from the store, but for it to be useful in game I need to animate the dissolve amount. But that's not a regular property of "material."

 

That's where all of the various GetXXX and SetXXX methods on Material come into play:

See: https://docs.unity3d.com/ScriptReference/Material.html

For example:

• SetColor https://docs.unity3d.com/ScriptReference/Material.SetColor.html
• SetFloat https://docs.unity3d.com/ScriptReference/Material.SetFloat.html
• SetTexture https://docs.unity3d.com/ScriptReference/Material.SetTexture.html

etc...

 

You mean a shader like this? The answer should contain all necessary details. Though when you use a shader from the store, you may have to figure out how those properties are called.
