Using a decal in a blueprint

I have a rally car inside a blueprint, I wanted to use decals to project “sponsor logos” onto the car. After creating the material I can drag it into my scene and adjust it fine, however there appears to be no way or putting it inside a blueprint.

Is there another way I can do this (without doing it in a modelling package).

Actor can’t do much by themselves in rendering, so for all visual features there usally a component. So what you looking for is Decal Component ;] Note that in your use case you don’t need decal, this can be made using normal material on the car with texture parameter, decals are mainly for decals that can be projected on any position, but if you gonna do that in same place statically you could as well do it on material of a object
