I keep coming back to writing rendering features that need to set values on a shader used in multiple passes. However the properties are inherited across passes and changing them when executing a new blit is ignored. A: Skip blitter and implement my own blit function? B: Cache / pool material instances depending on feature. C: Modify global state. I am leaning towards testing A but the Blitter is really pushed as the thing to use now. Do you have any other suggestions?
#Use Blitter with reliable material properties.

Sharing /separating materials is probably the most straightforward and recommended way IMHO.

I´ll probably end up using a list of instanced materials just to set one int per pass 😛

That's fine. That's what they are for. To provide property values to a shader.
