Hello!
I’m trying to apply texture variations of the same material to multiple objects. The idea is that each object have the same material but with a variation of texture, dirty different windows for example, but not do it manually.

Hello xyth,
Alternatively to this method is using Material Instances. This way you can also preview in realtime what your material will look like.

Sure… That is the first part to set up the Material Instance. This is just further documentation unless more information is needed on the Instance itself.
