How can i change material color of multiple objects inside blueprint?

Yes, i knew about it, but since it’s not a single mesh but grid of meshes i couldnt figure it out.
What I’ve done is upon construct every instance is added to array, then on component hit I search through array of meshes (also created in construction script) to get index, and i use this index to get exact tile from grid and set it color with vector paramter value.
