Hi Everyone,
I'm trying to set up some automated Mental Ray scripts for our studio
artists. I'm having some difficulties accessing all the proper variables
within Mental Ray. Specifically setting the Image Based Lighting.
I have created IBLShapes, set their attributes and connected the IBL to
'mentalrayGlobals.imageBasedLighting' yet when I set an HDR map (done
manually for the time being) and render, I get no IBL information and a
warning:
*Warning: (Mayatomr.Nodes) : mentalrayIbl1: IBL ignored. File texture not
found, or constant black input color. //*
I'm very sure there is an attribute I'm not connecting somewhere, but I
cant spot it.
Tracing Mayas output window I can see the miCreateIbl function (C:/Program
Files/Autodesk/mentalrayForMaya2014/scripts/createMentalRayIndirectLightingTab.mel).
I don't believe I missed anything in the Create or Update IBL functions
Does anyone have any suggestions?
Thanks
Enter code here...
import pymel.core as pm
# Load MentalRay Plugin
if not pm.pluginInfo('Mayatomr', q=1, l=1):
pm.loadPlugin('Mayatomr', qt=1)
#Set MentalRay Options
pm.setAttr('defaultRenderGlobals.ren', 'mentalRay', type='string')
pm.setAttr('miDefaultOptions.globalIllum', 1)
pm.setAttr('miDefaultOptions.globalIllumAccuracy', 500)
pm.setAttr('miDefaultOptions.finalGather', 1)
pm.setAttr('miDefaultOptions.finalGatherRays', 500)
pm.setAttr('miDefaultOptions.finalGatherPresampleDensity', 5)
pm.setAttr('miDefaultOptions.finalGatherPoints', 125)
# Add IBL
if not ibl:
ibl = pm.shadingNode('mentalrayIblShape', al=1)
pm.connectAttr(ibl+'.message','mentalrayGlobals.imageBasedLighting')
pm.xform(ibl, s=[5000,5000,5000])
pm.setAttr(ibl+'.primaryVisibility', 0)
pm.setAttr(ibl+'.visibleInEnvironment', 1)
pm.setAttr(ibl+'.visibleInReflections', 1)
pm.setAttr(ibl+'.visibleInRefractions', 1)
pm.setAttr(ibl+'.visibleInFinalGather', 1)
#set Image path in UI (done manually for now)
