How to use those methods:
virtual void CalcTransparency(PluginMaterial* mat, VolumeData* vd);
virtual void CalcAlpha(PluginMaterial* mat, VolumeData* vd);

even if i set information about what my plugin requires from the raytracer, like this:

LONG ParticleVolume::GetRenderInfo(PluginMaterial *mat)
{
     return SHADER_TRANSPARENCY|SHADER_VOLUMETRIC|SHADER_ALPHA;
}

program never enter to this method. Only CalcVolumetric and CalSurface work.

It is easy to check with ParticleVolume from sdk.
Just write
     GePrint("CalcTransprarency"); in ParticleVolume::CalcTransparency <--- it never apper in console window.

it will be called, but you the shaded objects have to be in a shadowed area. check this example file with the ParticleVolume example from the SDk. CalcTransparency will be called.
