Dynamically changeable textures/particles


The question is: how to make things like a car getting dirty while the game is on via C++? Or at least, what are the blueprints possible for that kind of dynamics? Thnx.

I guess what you are looking for is how to apply decals on your surfaces, it is more like adding a new texture onto your current one.

You need to look at blending.
In C++ create a dynamic instance material and you can update the properties.

Thank you ever so much for your promting and help, guys !
I’ll be digging in those directions.
