Global options - Max Depth

[sherridge101]

Hi all,

is there a way to set the 'Global max depth' for reflection and refraction independently?

cheers,

Steve

You can in Python Scene Access...
1) Get all materials
2) Set all materials

Do not forget that in render global, the "max depth" in an override depth, not a clamp depth...

Hi bigbossfr,

great, thanks for that.

Would that be something a non programmer (like myself) could do?

Sorry for the late reply. I did this in 5 mins :

import vray.utils as vr

def setMaxDepth(reflMax=None, refrMax=None):
    refracAttrs = ["refraction_depth"]
    reflecDepth = ["trace_depth", "reflection_depth"]
    for node in vr.findByType("*"):
        allAttrs = vr.getPluginParams(node)
        for attr in refracAttrs:
            if refrMax and attr in allAttrs and int(node.get(attr)) < refrMax:
                node.set(attr, refrMax)
        for attr in reflecDepth:
            if reflMax and attr in allAttrs and int(node.get(attr)) < reflMax:
                node.set(attr, reflMax)

setMaxDepth(reflMax=20, refrMax=10)

Add this code into "Post-translate python script" in Maya render global ---> VRay common

Change this last line with you max depth : setMaxDepth(reflMax=20, refrMax=10)

If you want just max reflection depth to 20 : setMaxDepth(reflMax=20)

If you want just max refraction depth to 20 : setMaxDepth(refrMax=20)

Or both : setMaxDepth(reflMax=20, refrMax=20)

Vlado : i see an attribute : mtl_limitDepth in vraySettingsOptions. It is what i am thinking ? (a clamp?)

Nope; it's the same the global V-Ray option in the Maya interface, so it's an override, not a clamp.

Best regards,

Awesome, cheers bigbossfr.
