Maya VrayMtl attribute shorthands

[dgruwier]

Hi, we're trying to open a lookdev maya scene that contains vray shaders on a machine that doesn't have vray, so the vraymtl attributes only exist as shorthands. Is there somewhere I can see what these shorthands mean? For example, I'm pretty sure "rlc" is reflection color and "rlg" is reflection glossiness, but what are the rest? Where can I find this information?

igi 0.0
rlc [(1.0, 1.0, 1.0)]
rlg 0.3333333432674408
uf 1.0
fde 1.0
gfr 1.0
ggxog 0.0
uro 1.0
and 0.0
afs 1.0
cth 0.0010000000474974513
brdf 3.0
omode 2.0
oc None
dc [(0.0022464534267783165, 0.0060036275535821915, 0.009642471559345722)]

Hello!

You can use a machine which has V-Ray for Maya installed and execute in the script editor the following MEL to get the long attribute name:

attributeQuery -node "<nodeName>" -longName "<shortAttributeName>";

This way you can get the following information:
igi -> illumGI
rlc -> reflectionColor
rlg -> reflectionGlossiness
uf -> useFresnel
fde -> fixDarkEdges
gfr -> glossyFresnel
ggxog -> ggxOldTailFalloff
uro -> useRoughness
and -> anisotropyDerivation
afs -> affectShadows
cth -> cutoffThreshold
brdf -> brdfType
omode -> opacityMode
oc -> outColor
dc -> diffuseColor
