volume data shading failures

#1

Hi,

I tried to use the following nodes with volume shader data of nParticles/fluids (n/f):

  1. tripleShadingSwitch (t)
  2. choice ©
  3. layered texture (l)

In essence, nothing worked in contrast to identical setup with surface shading data.
Moreover, Maya crashed several times when I started the render.

  1. input connections for t : n/f.instObjGroups[0] -> t.inShape and shadingData -> t.inTriple
    output connections for t : t.output -> volumeShader.outColor
    result : both sw/MR failed

  2. input connections : shadingData -> c.input[]
    output connections : c.output ->volumeShader.outColor
    result : both sw/MR failed

  3. input connections : shadingData ->l.inputs[0].color
    output connections : l.outColor -> volumeShader
    result : both sw/MR failed ( I should better say the result gives totally weird colors and produces a strong glow )

So, are these nodes not made for volume data?
