Fading between material and translucent material on cesium world terrain - Unreal

Cesium for Unreal
1

Hi there,

I am trying to fade between my satellite imagery to a custom shader for the cesium world terrain tile set and cannot figure out where i would do this. My current setup is this - Using the layering system in the Material Instance

But I want this material to switch out or swap to a custom shader controlled by the sequencer.

So 2 questions:

  1. Is there a way to swap or lerp between the 2 materials using ONE of those slots (Material)
  2. Is there a way to swap or lerp between the 2 materials using TWO of those slots (Material + Translucent Material)

Any other ideas welcome!
Thanks, J.

Hi @jsimich,

As far as I know there’s no way to lerp between materials. Unreal meshes are rendered with a single material.

Instead of thinking about it as using two materials and blending between them, think about creating one material that can render “either way” and blending between them internally using a parameter. You’ll probably want to put the parameter in a MaterialParameterCollection to make it easy to update.
