It’s pretty simple if you use dynamic material instance.
1.Create One material
2.Add both of your textures between which you want to change over time
3.Add Lerp node and connect it’s alpha to scalar parameter, name scalar parameter since it will be the handle to change between two textures. Here’s simple example
I have two materials, one of them is holographic one which connects only with Emissive and Opacity in this material window.
The second one is a compicated texture with normal map etc., both texures comes from Unreal Marketplace, so they have loads of stuff going on. And this second material (texture) goes to all of the rest.
Somebody showed me this method, but only if those two materials shared those plug-ins (Like for example Base Colour), so then I could really do lerp and it was alright. But in this case I don’t know what to do.
