VRAY Material Settings Update

Rendering V-Ray

How could I update the following settings in VRAY

	Reflection IOR should be 1.6 
	Refraction translucency set to SSS
	SSS colour set to the same as the Diffuse texture slot
	SSS amount 0.3
	Bump set to 40 (not 1)

How can I script this in rhVRay, I have many materials and I want to update all vray materials with these settings…
The documentation is lacking or maybe im just dense
Thank you @Nikolay

Hi, here is the script you need

#! python3
import rh8VRay as vray

with vray.Scene.Transaction() as t:
    for brdf in [vray.Scene[material.brdf] for material in vray.Scene.Materials]:
        if brdf.Type != "BRDFVRayMtl":
            continue

        print(f"Processing: \"{brdf.Name}\" ...")
        brdf.fresnel_ior_float = 1.6
        brdf.translucency = 6
        brdf.translucency_color_color = brdf.diffuse_color
        brdf.translucency_amount = 0.3
        brdf.bump_amount_float = 40

Mind that this is python 3 code for Rhino 8
for IronPython 2.7 (R7) the script would look a bit different
