Refraction Bounces limited to 3?

[grant_warwick]

I can't get refractive materials matching on the farm.
Testing indicated the farm is limiting the refraction bounces on a material, even if overrides are set.

The farm still won't give an exactly the same result even if I limit refraction though but it's much closer

The material has reflect on back side ticked
