SetColor vs SetFloat vs SetGlobalFloat RE minimizing material change

https://docs.unity3d.com/2021.1/Documentation/Manual/SRPBatcher.html

states

"In Unity, you can modify the properties of any Material at any time during a frame. However, this has some drawbacks. For example, there is a lot of work to do when a DrawCall is using a new Material."

I guess "new Material" means "same Material having changed properties".


Hi,

I like to minimize material changes for ~10,000 GameObjects

Currently my Coroutines use

SetColor

.

1. Is

   SetFloat("_Color")

   the same as

   SetColor

   ?
2. Is

   SetGlobalFloat

   avoiding Material change per GO, note GOs are grouped into groups having the same sharedMaterial within but distinct across groups?
   If yes, can I duplicate Shaders on the fly? How?

What else do you have in mind RE minimizing material change? I use the Standard built-in Pipeline.

 

Is there a difference wrt above in the URP or HDRP (BRG in HR excluded) ?
