Making a material dissolve overtime

There’s a couple tutorials on youtube on how to make dissolve effects but how would you make them dissolve over time from an interaction? A lerp? A timeline?

Exactly the same method, you just trigger it with the interaction.

The problem is they aren’t making a full dissolve animation. It’s the set up on how to make them. They don’t actually show how to affect the progress of the dissolve. How would I pull that out to alter it in a blueprint interaction?

like at the end it shows you the “progress” variable adjusts the amount of dissolve it has. How do I pull that out and cause it to happen over the course of a few seconds?

Make a new BP and put a mesh in it.

Give the mesh a dynamic material instance in the constructor

( set the material ).

Then, later in the BP, you can control the parameter like this

Awesome! Thank you for your help I’m going to go try it right now

Nevermind! I got it, I had promoted the DMI to a local variable and was using a global variable in the event graph that what was causing it not to work!
