Duplicating Shaders for adjustments of sub items - which impact on render time?

[BeneZ]

Hello,

I have a scene with a UDIM UV-layout.
It means many items were sharing the same material, which comes normally very handy.

Now I have the situation, that I need to trim several objects individually (for example Color Correct of different diffuse tweakings, or different reflection strength)

For my workflow:
Does it increase rendertime, when a shader is multiple times in the scene, but using the same maps for input?
The maps have a resolution up to 8k.

Or any other recommendation here?
Thanks

Hi, thanks for posting.

There should be no effect on render time but on the amount of memory that is taken. As long as you use the same image texture the RAM consumption will be the same.
