Is their anyone know where I did wrong?

The instances of a single Instanced Static Mesh Component can only have 1 mesh and 1 material. What you’re doing will not work. Whenever you assign a material, you do not really assign it to an instance - you assign it to all instances of this one component.

You have some options:

• you could have 2 ISMc:

The material can be pre-set on the component in the details panel.

• instead of ISMc, you could use as many regular Static Mesh Components as there are lights:

• there is also a more involved technique - Custom Primitive Data

How to add a hit count (health points) to individual instances?

The name of the game is Custom Primitive Data (check docs at the bottom). The material for a brick: each instance stores a float which is used to Lerp between 2 colours (to visualise hits remaining) this can (and probably should) get prettified [image] Making a brick wall: create a bunch of instances and store their data in an int | int Map instead of an integer, you could have a struct and hold all kind of data here; perhaps this brick is worth some coins, or explodes when destroyed and …

This would actually allow you to achieve what you want. 1 ISM, 1 material, as many colours as you need.
