Vray Prepass/Irradiance map error

[sohoklai]

Recently, I have installed Vray and 3DS Max in another computer(Slave). However, even the settings are exact imports from my main machine, the render appears to be wonky, especially when in Distributed Rendering, 2 machine render out the same image but the image stitches together wrong.

 

After troubleshooting for some time, it appears the Pre-pass is all over the place with the Slave computer,

 

Pre-Pass from my main workstation:

 

Pre-Pass from my Slave workstation:

 

Restatement: The settings are exactly the same, Slave's setting is imported from main Workstation

 

They are both using irradiance map as GI main, light cache as secondary bounces.

Brute Force is working perfectly fine in both machines.

 

Can anyone help me out?
