Why use dynamic materials？

[iZerat]

I don’t quite understand why dynamic materials should be used. They can be modified through the functions of the blueprint. It seems that dynamic modification can also be achieved using common materials.

Moreover, I have tried it to be work when running sequences and games.

Can dynamic materials modify more attributes? Colors or float can be modified in common materials. Currently in my project, only these need to be modified. Compared with common materials, do dynamic materials consume more resources or save more resources?

When used with a non dynamic material, the “Set Parameter Value” nodes will automatically create a dynamic material instance under the hood and replace the current material with that instance. You cannot modify parameter values of non-dynamic materials at runtime, unless using a Material Parameter Collection.

“Under the hood” of the mesh function is the creation of a dynamic material instance…
