Increasing Emission Intensity of an Individual Object

Hello,

I've seen there is a way to increase the emission intensity of a material at runtime using a script. Is there any way to increase the emission intensity of a single object and not all objects using that material? For instance, if I have an enemy with an emissive eyes material and I want all enemies' eyes to flicker intensity at different times. Or do I have to create individual materials for each?

 

In code, if you use and modify the

material

property of a Renderer, it will create a new unique material for that renderer and therefore you will only modify the material for that one renderer.

If you use the

sharedMaterial

property, it will change the material that all the objects using that material are sharing, and thus modify all of them.

Please read the documentation for more information:

That's very helpful, thank you!
