is it possible to change emission value in code

Unity Engine
1

can the emission value brightness be changed in code, i have looked around but nothing seems to work properly, and if it can be done is it possible to do this on a clone of a prefab without changing it on other clones of the same prefab

thanks in advance as i am having great headache with this

[MaterialName].SetColor(“_EmissionColor”, (colour*brightness float));

e.g

MyMaterial.SetColor(“_EmissionColor”, Color.blue*1.5f);

Hope that helps
