In an Instanced Static Mesh, in one instance, update material at runtime

Hi!

I’m using Instanced Static Meshes with this Material:

In one instance, I need to increase the value of the ‘Multiply’ node at runtime and then lower it after a few seconds.

How can I do it?

Thank you!

set num custom data floats to 1 on the ism component
swap that multiply for a perinstancecustomdata node in the material
then per instance call set custom data value with index 0
raise it and lower it again on a timer for that one instance
