v.4 shader don't work properly in v.2020

[vesta]

Hello
I'm on V.4.05-R7 and I have a composite material shader that don't work properly when I try to render it in V.2020 on another farm.
Is there a way to fix that avoiding to install the v.2020 on my machine?
thanks a lot
Giuseppe

Could you please test it in master with 2020.1.4 plugin? And send a sample scene if it's still not working
